A toothless sprocket for use with a chain saw on a stone cutting machine

Abstract

The invention relates to a toothless chain wheel matched with a chain saw on a stone cutting machine. The toothless chain wheel comprises a chain wheel body. A groove is formed in the outer edge of the chain wheel body in the radial direction. A plurality of through holes matched with oblique cone head screws are formed in the position of the groove of the chain wheel body at intervals. One end of each through hole is a tooth hole, and the other end of each through hole is a conical hole. A roller is arranged in the position of each through hole of the groove and composed of a flange bearing, a steel sleeve, a thrust gasket and the corresponding oblique cone head screw. A thread is arranged at the tail section of each oblique cone head screw, a cylindrical screw rod is arranged at the middle section of each oblique cone head screw, and an oblique cone head is arranged at the head section of each oblique cone head screw. In the groove, the steel sleeves are closely assembled on the outer sides of the flange bearings, the thrust gaskets are arranged on one sides of the fine ends of the flange bearings, and the tail sections of the oblique cone head screws sequentially penetrate the conical holes, the thrust gaskets and the flange bearings of the toothless chain wheel and are screwed with thread holes of the toothless chain wheel. The flange bearings and the thrust gaskets are in sliding fit with the cylindrical screw rods and can freely rotate. According to the toothless chain wheel, rolling friction is achieved during work; and during high-speed running, silencing is achieved, and friction and vibration are low.

Description

Technical field [0001] The invention relates to a toothless sprocket matched with a chain saw on a stone cutting machine. Background technique [0002] The inventor previously applied for the utility model "Guide Wheel Drive Device Matched with Stone Cutting Chain Saw" Patent No.: ZL2013201708066, application date: 2013.4.8; the teeth of the drive guide wheel mesh with the teeth of the chain saw and belong to sliding friction. When working, the tension of the chain saw and the high-speed operation of the driving guide wheel cause high temperature, high noise and vibration at the sliding friction point at the meshing point. Since the stone cannot be lubricated when cutting, the teeth of the chain saw and the driving guide wheel wear out quickly and have a short life, which also affects the cutting quality of the stone, especially when cutting large granite slabs. Summary of the invention [0003] The purpose of the present invention is to provide a toothless sprocket matched with...

AI Technical Summary

Problems solved by technology

Since the stone cannot be lubricated when cutting, the teeth of the chain saw and the driving guide wheel will wear out quickly, and the service life will be short, which will also affect the quality of stone cutting, especially when cutting large granite slabs.
