Synchronous belt wheel

Abstract

The invention provides a synchronous belt wheel. Mounting grooves are uniformly distributed around a wheel shaft support plate; wheel shafts are fixedly welded in the mounting grooves; all the wheel shafts are annularly arranged around the wheel shaft support plate; the middle parts of the wheel shafts are welded in the mounting grooves; annular synchronous belt limiting blocks are fixedly weldedat the left ends of all the wheel shafts; positioning holes are annularly arranged in the synchronous belt limiting blocks; and the left ends of the wheel shafts, annularly arranged, are inserted in the annular-arranged positioning holes for fixed welding. The wheel shafts are fixedly welded in the mounting grooves uniformly distributed around the wheel shaft support plate; every two wheel shaftsare spaced; the wheel shafts are fixedly welded in the positioning holes of the synchronous belt limiting blocks; because of gaps between the wheel shafts, gaps between the synchronous belt limiting blocks and the wheel shaft support plate, and hollow holes, such garbage as sand and stones can be leaked to prevent blockage or wear of the synchronous belt wheels; and outer ends of the synchronous belt limiting blocks exceed the wheel shafts to limit and stop the synchronous belts to prevent deviation or fall of the synchronous belts, so that the product quality is improved.

Description

Technical field [0001] The invention relates to the field of synchronous belts, in particular to a synchronous belt wheel. Background technique [0002] The timing belt needs to be put on a timing pulley for operation. During transportation, sand, stones and other garbage will enter the timing pulley, which will cause damage or jamming of the timing pulley and cause mechanical failure. Therefore, there is a need for an improved timing belt wheel that does not have sand, stones and other garbage entering to cause damage or jamming. Therefore, it is very necessary to solve this problem. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a synchronous belt wheel, which welds and fixes the two spaced wheel axles through uniform installation grooves around the wheel axle support plate, and then welds and fixes the wheel axles in the positioning holes of the timing belt limit block. Due to the gap between the axles, the gap...
