Novel friction clutch for walking tractor

Abstract

The invention relates to a novel friction clutch for a walking tractor, which is characterized in that the conical disc type friction clutch has a stationary fitted inclined surface; the stationary fitted inclined surface is installed on a transmission shaft on one side of a gear case; a rotatable fitted inclined surface and the stationary fitted inclined surface are oppositely installed on the transmission shaft; an operating lever is connected with the rotatable fitted inclined surface; a fly wheel is installed on the transmission shaft on the outer side of the rotatable fitted inclined surface through a bearing; a formed inner conical surface is formed on the outer side of the fly wheel; a drive disc is a conical body, the conical degree of the drive disc is the same as that of the inner conical surface at the inner side of the fly wheel, and the drive disc is installed on the transmission shaft on the outer side of the fly wheel through a spline; and a compression spring is installed on the transmission shaft on the outer side of the drive disc by a nut.

Description

Technical field: [0001] The invention relates to a walking tractor friction clutch, in particular to a novel walking tractor friction clutch, which belongs to the technical field of agricultural machinery. Background technique: [0002] The structure of the clutch is an important transmission part of the walking tractor. At present, in the structure of the clutch of the walking tractor, the multi-disc friction clutch is mainly used. Although the clutch of this structure has the advantages of compact structure and high friction, However, due to structural reasons, this kind of clutch also has certain defects. 1. The safety is poor. This kind of clutch is due to its driven plate and driven shaft in a state of free rotation under the disengaged state. When rotating at high speed, dust and other foreign matter can easily enter between the main and driven plates, resulting in poor or unclear separation, not only easy to damage related parts, but also cause certain safety accident...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of walking tractor friction clutch, which overcomes the defects of poor safety, high cost, high failure rate, and inconvenient installation and maintenance caused by the existing clutch due to structural reasons.

[0005] Beneficial effects: the present invention adopts the cone-disc friction clutch to replace the existing flat-disc friction clutch, so it overcomes the poor safety, high cost and failure rate of the existing clutch due to structural reasons. Defects of higher height and inconvenient installation and maintenance
