Driving bevel gear shaft

Abstract

The present invention discloses a driving bevel gear shaft. The driving bevel gear shaft comprises a vertically disposed bevel gear shaft. A lower end of the bevel gear shaft is provided with a bevel gear; an upper end of the bevel gear shaft is provided with an external spline; a first bearing mounting seat and a second bearing mounting seat are disposed on the bevel gear shaft between the bevel gear and the external spline; the first bearing mounting seat is close to the bevel gear; and the second bearing mounting seat is close to the external spline. According to the bevel gear shaft disclosed by the present invention, an axial fixing hole and an inclined hole for fixing the bevel gear shaft are disposed on an upper end surface and an upper end of the bevel gear shaft respectively, and when the upper end of the bevel gear shaft is connected to another member, a fixing pin can be inserted into the axial fixing hole and the inclined hole for fixing the bevel gear shaft, so that the bevel gear shaft can be more reliably and securely fixed with the another member in axial and radial directions; additionally, a hole bottom of the inclined hole for fixing the bevel gear shaft is downward inclined, so that sliding of the inserted fixing pin from the hole is effectively avoided. The entire driving bevel gear shaft is simple in structure, and is firm and durable.

Description

Technical field [0001] The invention relates to a shaft, in particular to a transmission bevel gear shaft. Background technique [0002] The micro-tiller is powered by a small diesel engine or gasoline engine, and has the characteristics of light weight, small size, simple structure, etc. The micro-tiller is widely used in plains, mountains, hills, dry land, paddy fields, orchards and other places. It can be pumped with corresponding equipment , Power generation, spraying, spraying, etc., and can also be towed for short-distance transportation. The tiller can be used freely in the field, which is convenient for users to use and store, eliminating the trouble that large agricultural machinery cannot enter mountainous fields. Farmers and consumers are the best choice to replace cattle farming. The power part of traditional tillers generally includes power devices and transmission devices. The current walking transmission devices of tillers use belts, chains and other transmission m...

Problems solved by technology

[0002] Tillers are powered by small diesel engines or gasoline engines, and have the characteristics of light weight, small size, and simple structure. Tillers are widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. They can be pumped with corresponding equipment. , power generation, spraying, spraying and other operations, and can also be towed by a trailer for short-distance transportation. The tiller can be used freely in the field, which is convenient for users to use and store. It saves the trouble that large agricultural machinery cannot enter the mountainous fields. The best choice for the majority of farmers to replace cattle plowing. The power part of the traditional micro tillage machine generally includes the power device and the transmission device. At present, the micro tillage machine travel transmission device adopts transmission mechanisms such as belts and chains, which has low transmission efficiency and low transmission efficiency. The power loss is large, the chain is easily damaged during transmission, and the maintenance is inconvenient, etc.
