an improved gear

Abstract

The invention relates to an improved gear. The improved gear comprises a gear outer ring, a gear inner ring and a connecting shaft, wherein the gear inner ring is detachably arranged in the gear outerring, the gear inner ring is connected with the connecting shaft through a key, the gear outer ring comprises a gear body and a connecting auxiliary piece, the gear inner ring comprises a fixed ringbody, a fixing piece, a first connecting ring, a second connecting ring and a connecting piece, the fixing piece comprises a fixed block, a tensioning frame, a limiting column and a fixed pressing rod, and the connecting piece comprises an adjusting screw, a connecting rod and a retraction sleeve. According to the improved gear, the gear outer ring is connected with the gear inner ring in a detachable manner, disassembly and assembly are convenient, when the device works for a certain time, the abrasion is serious, the whole gear does not need to be disassembled, only the gear inner ring needsto be disassembled and replaced, so that the working cost is reduced, the waste of raw materials is avoided, the size of the gear inner ring can be correspondingly adjusted according to the requirements of the use occasion, and the application range is wide.

Description

technical field [0001] The invention relates to the field of transmission components, in particular to an improved gear. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. China's gear industry has developed rapidly during the "Tenth Five-Year Plan" period. In terms of market demand and production scale, China's gear industry has surpassed Italy in the global ranking, ranking fourth in the world. [0003] Since gears are used more and more widely, and the size of gears is mostly fixed, it is necessary to use gears of corresponding shape and size according to different application occasions. The following problems exist in the process of processing and using gears: [0004] (1) Gear molds are needed in the processing process. Most of the middle and low-grade gear molds can be produced in China, and the high-end gear molds mos...

Problems solved by technology

[0004] (1) Gear molds are needed in the processing process. Most of the middle and low-grade gear molds can be produced in China, and the high-end gear molds mostly rely on imports. Most of the domestic gear factories make gear molds themselves, and a special section or workshop is required. To undertake this work, the processing cost is high;

[0005] (2) After the gear has been used for a long time, the contact surface between the gear and the shaft will be worn. Since most of the existing gears have an integrated structure, in order to ensure the stability of the follow-up work, the entire gear needs to be replaced in time, which increases the work. cost, and caused a certain degree of waste
