Application and Analysis of the Oil-lubricated Bearings in the Tower Crane: tower cranes, in recent years Due to the rapid development of high-rise buildings, tower cranes The use of the factory has been greatly promoted, and the production capacity of the factory is far from meeting the market. demand. To increase productivity and save costs, we seek to use standard parts instead of non-standard parts to reduce the manufacturing cycle and save manufacturing costs, and can Stable part manufacturing quality. Among them, the climbing claws and jacking rollers in the jacking frame of the tower crane are commonly used. With cast copper alloy bearings, due to the rising price of copper materials in recent years, The cost of cast copper bearings is getting higher and higher. Some tower crane manufacturers in order to save To reduce the cost, change the cast copper alloy bearing to the cast iron sliding bearing, Because the climbing claws and the jacking rollers in the jacking frame are in the process of jacking up the tower crane Bearing a large load, the lubrication of the cast iron sliding bearing and the shaft is easy to lose. The thin-walled cast iron sliding bearing is also easy to break under the action of external force. If it is damaged, it will cause the failure of the support point during the jacking process, and in severe cases, the tower crane will be damaged. of safety incidents. Therefore, if standard oil-free lubricated bearings are used instead of cast copper Bearings can ensure the bearing capacity and lubrication conditions of cast copper alloy bearings, It can also achieve the low cost of cast iron bearings, which makes us both achieve tower cranes. It is a subject that saves processing costs and material costs. And it can avoid neglect due to overemphasis on reducing the manufacturing cost of tower crane requirements for safe use of the product.

In order to use oil-free bearings on tower cranes, we The selected verification analysis was carried out: 1 Application characteristics of oil-free bearings Oil-free lubrication can provide better self-lubrication, with good wear resistance, The friction coefficient is small and the service life is long. Oil-free bearings have good running-in performance, Low noise, no pollution, good corrosion resistance; transfer film formed during operation To protect the grinding shaft. Oil-free lubricated bearings have an appropriate amount of elastoplasticity, It can distribute the stress on a wider contact surface, which can improve the bearing capacity capacity, especially for heavy loads at low speeds, where refueling is impossible or difficult Places, can be used without maintenance or less maintenance, the friction coefficient is small, use long life. 2. Material structure of oil-free bearings Oil-free bearings are made of plastic-bronze-steel backed three-layer composite material compound. Based on high-quality low-carbon steel plate, the intermediate sintered porous bronze layer, the surface is rolled with a mixture of PTFE and lead. (1) Ptfe and lead mixture 0.01-0.03 mm, one A wear-resistant material that can form a transfer film to protect the grinding shaft during operation. (2) The copper powder layer is 0.2 to 0.35 mm, and the PTFE and lead The bonding strength with the steel plate has good bearing capacity and wear resistance. At the same time, copper is a good thermal conductive material, which can quickly transfer the bearing heat generated during operation. (3) Low carbon steel 2 ~ 2.3 mm, improve the bearing capacity and heat transfer. (4) The copper/tin electroplating layer is 0.002 mm, so that the bearing has good resistance Corrosion function. 3 Physical and mechanical properties of oil-free bearings The tower crane uses standard oil-free lubricating bearings instead of cast copper bearings, and the selection of oil-free bearings is checked and analyzed. The three indicators of P, maximum linear speed V, and maximum PV value are all lower than the allowable values, which can save a lot of processing costs and material costs, and the cost of oil-free bearings Only 10% of cast copper alloy bearings. Key words: non-oil lubricated bearing tower crane check calculation analysis Application analysis of oil-free lubricating bearings in tower cranes Application and Analysis of the Oil-lubricated Bearings in the Tower Crane (1) Oil-free lubricating bearings in the climbing claws on the tower crane jacking frame.

Jacking frame, slewing middle section, upper and lower support slewing bearing, tower cap, flat Weighing arm, counterweight, boom, trolley, cab, hoist The weight of the structure, slewing mechanism, luffing mechanism and other components, two without oil lubrication The working load of the plain bearing is approx. 630 000 N, a single shaft without oil lubrication The working load of the bearing is N = 315 000 N, the shaft diameter d = 50 mm, the bearing Length L = 55 mm. Substitute into the formula P = F/d L to calculate, specific pressure limit P = 114.5 N/m m2 , less than the physical and mechanical properties of oil-free bearings in the table Static load value 250 N/mm2 . Therefore, the specific pressure limit check is passed. (2) There is no oil-lubricated bearing for the pulley of the tower cap cable head of the tower crane. lasso The load of the head oil-free lubricated bearing is the weight of the cable, which is about 15 000 N, shaft diameter and bearing length of non-oil lubricated bearings and central axis of climbing jaws Bearing the same, because the working load is only 1/21 of the claw bearing, so the ratio Pass the pressure limit check. (3) There is no oil-lubricated bearing for the guide roller of the tower crane jacking frame. one The tower crane has a total of 16 guide rollers, and the guide rollers of the frame have no oil-lubricated shafts. The side of the superstructure of the tower crane that is mainly subjected to the lifting and heightening of the tower crane during the bearing work Axial force, no oil lubrication at this part, shaft diameter d = 35 mm, bearing length Degree L =30mm, the maximum specific pressure limit P =140 when the bearing is dynamically loaded Substitute N/mm2 into the formula P = F/d L to calculate oil-free lubrication The maximum working load of the bearing is 147 000 N. Due to the increase of the tower crane The height is the total weight of the superstructure of the tower crane is about 630 000 N, and when jacking The lateral force is much less than the total weight of the superstructure, and there are 16 The guide rollers jointly bear the lateral force, and it can be seen that each oil-free lubrication The maximum working load of the bearing of 147 000 N can meet the requirements of the working conditions. Therefore, the specific pressure limit check is passed. 5 Check calculation of the maximum linear speed V of the non-oil lubricated bearing The linear speed of the oil-free bearings in the three parts of the tower crane is far less than 2.5 m/s, this check is passed. Among them: the non-oil lubricated bearing of the climbing claw is static load, V is 0. The maximum linear speed of the cable head pulley without oil-lubricated bearing is The speed at which the lifting mechanism lifts the pull rod at low speed is 0.15 m/s. Sleeve guide The maximum linear speed of the roller bearing without oil lubrication is the jacking of the tower crane. Velocity, 0.0 133 m/s. 6 Verification of the highest PV value of non-oil lubricated bearings The PV value refers to the multiplication of the bearing under certain load and linear speed conditions. sum of accumulations. The PV value of the equipment is inversely proportional to the service life of the bearing, The PV value of the bearing should be as low as possible to ensure the safe PV value. Bearings will have a longer service life. Check calculation of the highest PV value of oil-free bearings in three parts of tower crane Performance indicators Relevant data Maximum specific pressure limit P Static load 250 N/mm2 Dynamic load 140 N/mm2 Maximum line speed V Dry friction 2.5 m/s Oil lubrication 5 m/s Highest PV value Dry friction 3.6 (N/ mm2 ) .(m/s) Oil lubricated 50 (N/ mm2 ) .(m/s) friction coefficient Dry friction 0.08~0.20 Oil lubrication 0.02~0.07 Table 1 108 CMTM 2011.06 Product ● Technology Product & Technology 7 Verification conclusion By checking and calculating the oil-free bearings of the three parts of the tower crane, The specific pressure limit P, the maximum linear velocity V, and the maximum PV value are all low within the allowable value to meet the usage requirements. 8 Actual use effect and conclusion Our factory combines the cast copper alloys of the three parts of the tower crane The gold bearing is replaced by an oil-free lubricated bearing. It has been used for nearly two years and has not developed Oil-free bearings that have been repaired and failed in use. Practice has proved that the use of tower cranes Replacing traditional cast copper bearings with oil-free lubricated bearings can save a lot of money The cost of processing and material costs, the cost of non-oil lubricated bearings is only 10% of copper alloy bearings, and can save a lot of metalworking man-hours.
