Description

Technical Field

[0001] The utility model relates to the technical field of elevator pulleys, in particular to a super wear-resistant elevator MC nylon pulley. Background Art

[0002] When the elevator is in use, pulleys need to be installed on the car frame and the counterweight frame so that the traction rope can pass around the pulleys to form different traction ratios. Its main function is to reduce the output power and torque of the traction machine, thereby improving the overall efficiency of the elevator system.

[0003] When the existing MC nylon pulley is used in conjunction with the traction rope of an elevator, the contact surface between the pulley and the traction rope lacks a self-lubricating mechanism, resulting in high wear of the MC nylon pulley, frequent maintenance requirements, and a short service life. Therefore, a super wear-resistant elevator MC nylon pulley is proposed to provide a set of super wear-resistant MC nylon pulley components for the traction rope of the elevator, and a self-lubricating mechanism is set on the contact surface with the traction rope to reduce the friction and wear between the traction rope and the pulley, extend the service life of the traction rope and the pulley, and reduce the maintenance cost. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a super wear-resistant elevator MC nylon pulley to provide a set of super wear-resistant MC nylon pulley components for the elevator traction rope, and a self-lubricating mechanism is set on the contact surface with the traction rope to reduce the friction and wear between the traction rope and the pulley, extend the service life of the traction rope and the pulley, and reduce the maintenance cost.

[0005] The technical solution adopted by the utility model to solve the technical problem is a super wear-resistant elevator MC nylon pulley, comprising:

[0006] Inner wheel;

[0007] An outer wheel portion is arranged on the inner wheel portion;

[0008] The self-lubricating part is arranged on the outer wheel part.

[0009] By adopting the above technical solution, a set of super wear-resistant MC nylon pulley assemblies is provided for the elevator traction rope through the assembly consisting of the inner wheel part, the outer wheel part and the self-lubricating part. A self-lubricating mechanism is set on the contact surface with the traction rope to reduce the friction and wear between the traction rope and the pulley. By reducing the wear, the service life of the traction rope and the pulley can be extended and the maintenance cost can be reduced.

[0010] Specifically, the inner wheel portion includes:

[0011] MC nylon axle;

[0012] At least one group of insert blocks is provided and arranged along the circumference of the MC nylon wheel shaft.

[0013] Specifically, the outer wheel portion includes:

[0014] MC nylon wheel cover;

[0015] The slots are provided in at least one group and are opened along the inner diameter of the MC nylon wheel sleeve;

[0016] Rope grooves, at least one set is provided and opened along the circumference of the MC nylon wheel sleeve;

[0017] An annular groove is provided in the rope groove.

[0018] By adopting the above technical solution and arranging the insert block and the slot, the contact area between the pulley and the traction rope can be independently disassembled and replaced, which can reduce the material cost.

[0019] Specifically, one end of the MC nylon wheel shaft and one end of the MC nylon wheel sleeve are both provided with corresponding threaded holes.

[0020] By adopting the above technical solution, the threaded hole can be used for riveting between one end of the MC nylon wheel shaft and the MC nylon wheel sleeve.

[0021] Specifically, the self-lubricating part includes:

[0022] A first graphite half ring is disposed in the annular groove;

[0023] The second graphite half ring is arranged in the annular groove.

[0024] Specifically, the diameters of the first graphite half ring and the second graphite half ring are consistent with the diameter of the annular groove, and the first graphite half ring and the second graphite half ring are glued and fixed to the annular groove.

[0025] By adopting the above technical solution, the good lubricity and wear resistance of the first graphite half ring and the second graphite half ring improve the self-lubrication and wear resistance between the pulley and the rope, so that the service life of the pulley is effectively increased.

[0026] The beneficial effects of the utility model are as follows: a set of super wear-resistant MC nylon pulley components is provided for the traction rope of the elevator through the assembly consisting of the inner wheel part, the outer wheel part and the self-lubricating part; a self-lubricating mechanism is arranged on the contact surface with the traction rope to reduce the friction and wear between the traction rope and the pulley, and the service life of the traction rope and the pulley can be extended by reducing the wear, and the maintenance cost can be reduced; through the arrangement of the plug block and the slot, the contact area between the pulley and the traction rope can be independently disassembled and replaced, and the material cost used can be reduced, and the problem that the existing MC nylon pulley lacks a self-lubricating mechanism on the contact surface between the pulley and the traction rope when used in conjunction with the traction rope of the elevator is solved, which leads to high wear of the MC nylon pulley, frequent maintenance requirements and short service life.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] To reduce wear, such as Figure 1-6 As shown, the super wear-resistant elevator MC nylon pulley described in the utility model comprises:

[0037] Inner wheel 1;

[0038] The outer wheel portion 2 is arranged on the inner wheel portion 1;

[0039] The self-lubricating portion is provided on the outer ring portion 2 .

[0040] When in use, a set of super wear-resistant MC nylon pulley assemblies is provided for the elevator traction rope through the inner wheel part 1, the outer wheel part 2 and the self-lubricating part. A self-lubricating mechanism is set on the contact surface with the traction rope to reduce the friction and wear between the traction rope and the pulley. By reducing the wear, the service life of the traction rope and the pulley can be extended and the maintenance cost can be reduced.

[0041] For example, Figure 3 As shown, the utility model also includes that the inner wheel portion 1 includes:

[0042] MC nylon axle 101;

[0043] At least one group of insert blocks 102 is provided and arranged along the circumference of the MC nylon wheel shaft 101 .

[0044] When in use, the MC nylon wheel sleeve 201 is supported by the MC nylon wheel shaft 101 .

[0045] In order to reduce material waste, for example, Figure 4 As shown, the utility model also includes that the outer wheel portion 2 includes:

[0046] MC nylon wheel sleeve 201;

[0047] The slots 202 are provided in at least one group and are opened along the inner diameter of the MC nylon wheel sleeve 201;

[0048] At least one group of rope grooves 203 are provided and are opened along the circumference of the MC nylon wheel sleeve 201;

[0049] The annular groove 204 is formed in the rope groove 203 .

[0050] When in use, the MC nylon wheel sleeve 201 can be inserted into the MC nylon wheel shaft 101 through the arrangement of the slot 202 and the plug block 102, so that during later maintenance, the inner wheel part 1 or the outer wheel part 2 can be replaced separately to reduce the material cost of the overall replacement and reduce material waste.

[0051] For example, Figure 3 As shown, the utility model also includes that one end of the MC nylon wheel shaft 101 and one end of the MC nylon wheel sleeve 201 are both provided with corresponding threaded holes 103 .

[0054] A first graphite half ring 301 is disposed in the annular groove 204;

[0055] The second graphite half ring 302 is disposed in the annular groove 204 .
