Abstract
The utility model discloses a nylon pulley with a copper inner lining bush. The nylon pulley is formed by pouring; and a copper inner lining shaft sleeve is arranged in the center of the nylon pulley and is adhered integrally with the nylon pulley. By the nylon pulley with the copper inner lining bush, the copper inner lining bush is arranged in the shaft sleeve in central shaft sleeve part of the nylon pulley, so that the nylon pulley can work for a long time, and the central shaft sleeve part is not heated and deformed.
Description
Technical field
The utility model relates to the pulley field, is specifically related to a kind of nylon pulley that is provided with the copper neck bush.
Background technique
Pulley is that a periphery has groove, the steamboat that can sway.The making material of pulley has metal, plastics, nylon etc., and wherein the nylon material pulley has multiple advantage, and is good like abrasion performance, self-lubricating property; Do not damage the mill parts, material is light, does not produce noise, running steadily; Cost is low; Safe in utilization or the like, nylon pulley is also approved at present, and extensively utilization.But find in the using process that use for a long time at pulley center axle sleeve position can the heating distortion.
Summary of the invention
The technical problem that the utility model will solve provides a kind of nylon pulley that is provided with the copper neck bush, long working, and the central axle sleeve position does not generate heat, and is indeformable.
The utility model is realized through following technological scheme:
A kind of nylon pulley that is provided with the copper neck bush, nylon material pulley casting forming, said nylon pulley center is provided with copper liner axle sleeve, is bonded into one with nylon pulley.
The further improvement project of the utility model is that said copper liner axle sleeve internal surface is provided with oil groove, is communicated with the oil hole in the axle sleeve outside.
The utility model further improvement project is that said oil groove vertically, laterally is uniformly distributed with staggered.
The utility model compared with prior art has following obvious advantage:
The utility model is owing to be provided with the copper neck bush at the central axle sleeve position, long working, and the central axle sleeve position do not generate heat, indeformable.
Description of drawings
Fig. 1 is the utility model side view.
Fig. 2 is the A-A sectional view of Fig. 1.
