Abstract
Composite lubricated contact system tension pulley, comprise seal ring (5) and axle (10), it is characterized in that: the no cunning moving axis bearing sleeve (4) that the band flange is housed on the described axle (10), the flange of this sliding bearing sleeve is near pillow block, be with antifriction-bearing box (3) on the no cunning moving axis bearing sleeve (4) of described band flange, wheel body (1) is housed on the described antifriction-bearing box (3), end cap (2) is equipped with in the both sides of described wheel body (1), between the no cunning moving axis bearing sleeve (4) of described band flange, axle (10) and the end cap (2) seal ring (5) is housed.The utility model makes assembly pulley driving efficiency in service life that obvious decline not take place, and two transmission devices and composite lubricated measure guarantee that pulley satisfies the requirement that service-free uses in 20 years.
Description
Technical field
The utility model belongs to the contact nets in electrified railways tension pulley.
Background technology
At present, the domestic single lubricated type of drive of the general employing of contact system tension pulley that is used for contact nets in electrified railways catenary and the control of contact wire constant tension, generally adopting has oil lubrication antifriction-bearing box type of drive, or adopts few oil, no cunning dynamic bearing type of drive.All there is weak point in these two kinds of type of drive.
When employing has oil lubrication antifriction-bearing box type of drive, guarantee that pulley can normally move by service-free in 20 years, must select the special high-performance lubricating grease.Whether the lubricating grease of selecting for use is reasonable, do not have respective standard temporarily and tests, appraises and decides.Can only select antioxidant, anhydrous for use, adapt to, make great efforts to make it to reach the purpose of long-acting use, but can not reliably guarantee to satisfy the requirement of long-acting use than low ambient temperature with than the lubricating grease of high ambient temperature.If the lubricating grease performance of selecting for use is lower, the driving efficiency of pulley will obviously descend, and make pulley can not satisfy the application requirements of high driving efficiency.
When adopting few oil, no cunning dynamic bearing type of drive, guarantee that pulley can normally move by service-free in 20 years, must adopt to scribble the plain bearing that ageing-resistant composite material or proprietary materials such as oil-containing powdered metallurgical material or copper sheathing embedding graphite are made.But plain bearing exists driving efficiency to be lower than the deficiency of antifriction-bearing box driving efficiency, and difficulty makes assembly pulley satisfy driving efficiency 〉=97% when rising, the requirement of driving efficiency during decline 〉=98%.
The utility model content
The utility model technical issues that need to address are: a kind of composite lubricated contact system tension pulley is provided, it can reach the purpose of long-acting use, satisfy the application requirements of the high driving efficiency of pulley, make assembly pulley driving efficiency in service life that obvious decline not take place, two transmission devices and composite lubricated measure guarantee that pulley satisfies the requirement that service-free uses in 20 years.
Technical solution of the present utility model is: composite lubricated contact system tension pulley, comprise seal ring and axle, it is characterized in that: the no cunning moving axis bearing sleeve that the band flange is housed on the described axle, the flange of this sliding bearing sleeve is near pillow block, the no cunning dynamic bearing of described band flange puts and is with antifriction-bearing box, on the described antifriction-bearing box wheel body is housed, end cap is equipped with in the both sides of described wheel body, between no cunning moving axis bearing sleeve, axle and the end cap of described band flange seal ring is housed.
The utility model compared with prior art has following advantage: the present invention is by adopting conventional lubrication antifriction-bearing box and oil-free lubrication plain bearing simultaneously, and together by textural association shown in the present, even can satisfy and in the equipment use, no longer give transmission place filling lubricating oil, fat, also can guarantee the requirement of the reliable and secure operation of transmission device of equipment, and the present invention only changes transmission shaft and can install and use in former conventional rolling bearing installing space, makes to adopt the present invention very convenient.
Invention adopts two groups of gear units that are made of no oily flange sliding bearing sleeve of cover in the antifriction-bearing box to form the transmission device of pulley.
Invention is assembled in two groups of above-mentioned gear units on the axle of tape spool platform in the middle of, and the flange of sliding bearing sleeve is near pillow block, make sliding bearing sleeve only with the work friction face generation slide relative of axle and pillow block.Two transmission devices of design-calculated and composite lubricated measure can make great efforts to guarantee that such pulley satisfies the requirement that service-free uses in 20 years like this.This structure design makes the loss of lubricating oil, fat performance degradation or lubricating oil, fat can not cause the reduction of the whole driving efficiency of assembly pulley substantially, therefore can make assembly pulley satisfy the utilization requirement of few maintenance, service-free in service life.

Specific embodiments
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Composite lubricated contact system tension pulley, comprise seal ring 5 and axle 10, it is characterized in that: the no cunning moving axis bearing sleeve 4 that the band flange is housed on the described axle 10, the flange of this sliding bearing sleeve is near pillow block, be with antifriction-bearing box 3 on the no cunning moving axis bearing sleeve 4 of described band flange, on the described antifriction-bearing box 3 wheel body 1 is housed, end cap 2 is equipped with in the both sides of described wheel body 1, between the no cunning moving axis bearing sleeve 4 of described band flange, axle 10 and the end cap 2 seal ring 5 is housed.
Pulley body 1 is used to bear external loads, and load is rationally passed to bearing.End cap 2 is used for the spacing of gear unit and sealing, adopts 2 altogether.Antifriction-bearing box 3 can adopt band common ball of leak free or roller antifriction-bearing box, is drive disk assembly, and it is good to satisfy technical performance during type selecting, can adapt to the requirement of working reliably and with long-term, adopts 2 altogether.The Nonlubricated bearing cover 4 of band flange is a drive disk assembly.It is good to satisfy technical performance during type selecting, can adapt to the requirement of working reliably and with long-term, adopts 2 altogether.Seal ring 5 is used for exclusion seal, adopts 2 altogether.Clamping plate 6 are used for load that pulley body is subjected to, after bearing, axle transmit, pass to other attaching partss.A pulley can only be arranged, also can make up other pulleys, constitute many pulley structures, adopt 2 altogether.Spring washer 7, packing ring 8 and nut 9 are used for fixing clamping plate and axle, totally 2 groups.Axle 10 is used to install two groups of gear units and other accessory.Have oil hole on the axle.Axle and the requirement up to specification of pillow block minus projections are adopted 1 altogether.Screw 11 is used for fixing between end cap and pulley body.Adopt 8 altogether, divide two groups of uses.
