Background
The gear shaft refers to a mechanical part that supports and rotates with a rotating part to transmit motion, torque or bending moment. Typically in the form of a metal rod, each section may have a different diameter. The parts of the machine that rotate are mounted on the shaft. The shaft can be divided into a crankshaft and a straight shaft according to the shape of the shaft line. According to the bearing condition of the shaft, the method can be divided into the following steps: the rotating shaft bears bending moment and torque during working and is the most common shaft in machinery; the mandrel is used for supporting the rotating parts to only bear bending moment without transmitting torque, and some mandrels rotate and other mandrels do not rotate; the transmission shaft is mainly used for transmitting torque and does not bear bending moment. In recent years, with social progress and high-speed development of science and technology, the use environment and conditions of the gear shaft are more and more diversified, and the requirements on the structure, the material and the performance of the gear shaft are higher and higher;
in the prior art, friction is generated between the outer side of the gear shaft and the supporting piece in the transmission process of the gear shaft, and the gear shaft is greatly abraded in the past, so that the service life is influenced; in addition, the gear shaft and the spline in the prior art are connected through the connecting piece, and the connecting piece can be subjected to large shear stress during the transmission process of the gear shaft, so that the gear shaft and the spline can be deviated, and the connecting piece can be broken.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that the skew takes place easily between having tooth axle and the spline among the prior art, and the shape axle is repaiied in a kind of finish rolling that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the design is a fine rolling modification gear shaft, which comprises a gear shaft body, one side fixed mounting of the gear shaft body is provided with a middle end shaft body, one side fixed mounting of the middle end shaft body away from the gear shaft body is provided with a thread shaft body, one side fixed mounting of the middle end shaft body away from the thread shaft body is provided with a spline shaft body, the gear shaft body, the middle end shaft body, the thread shaft body and the spline shaft body are of an integrated structure, a central shaft hole is formed in the central position of the gear shaft body, and the central shaft hole penetrates through the gear shaft body, the middle end shaft body, the thread shaft body and.
Preferably, an open slot is formed in one end of each rack of the gear shaft body, and two ends of each rack are of a chamfer structure.
Preferably, the outer side fixed mounting of well end axis body has the wearing layer, a plurality of louvres have all been seted up at the both ends of well end axis body, the louvre is around well end axis body evenly distributed.
Preferably, a key groove is formed in the outer side of the threaded shaft body, and the key groove is of a semicircular structure.
The utility model provides a pair of shape tooth axle is repaiied in smart rolling, beneficial effect lies in:
1. the gear shaft body, the middle end shaft body, the threaded shaft body and the spline shaft body are of an integrated structure, and connecting pieces are not needed to be butted between every two gear shaft bodies, so that the connecting pieces can be prevented from being damaged due to transmission among all parts;
