Description

Anti-radial-impact output shaft

Technical Field

The utility model belongs to the mechanical transmission field specifically is an anti radial impact's output shaft.

Background

At present, in order to prevent the output shaft from being damaged by the radial load or radial impact load at the end part of the output shaft, the output shaft used by the mechanical transmission mechanism on the market mostly needs to be provided with a radial bearing to protect the output shaft. The application of bearings to the output shaft, while improving the machining accuracy of the output shaft, also requires sufficient installation space and lubrication system for the transmission mechanism, which increases the manufacturing cost of the transmission mechanism. And when the radial bearing protection is not installed, the locking phenomenon is very easy to generate when the existing cylindrical output shaft is subjected to radial load.

SUMMERY OF THE UTILITY MODEL

The purpose of the invention is as follows: in order to overcome the deficiencies in the prior art, the utility model aims to provide an anti radial impact's that can reduce the machining precision requirement, simplify drive mechanism, reduce manufacturing cost, improve wholeness price ratio output shaft.

The technical scheme is as follows: an anti radial impact's output shaft, including casing and axle body, set up the slotted hole in the casing, the slotted hole matches with the axle body, the axle body includes terminal surface one, terminal surface two and side, the side links to each other with terminal surface one, terminal surface two respectively, the side is crossing with the slotted hole.

The intersection line of the side face and the slotted hole is circular. The first end face and the second end face are both circular. The first end face and the second end face are parallel to each other. The heights of the highest point and the lowest point on the cross section of the side surface are less than or equal to 0.015mm, and the height difference is adjusted according to different application working conditions. The shaft body is connected with the connecting shaft, and the connecting shaft extends out of the shell.

In a preferred mode, the slotted hole is cylindrical, the side face of the shaft body is drum-shaped, and the drum-shaped can be designed according to the stress condition and the use requirement, so that the material and the radian of the drum-shaped shaft body can be designed.

Another preferred mode is that the shell slotted hole protrudes towards the axial direction of the shaft body, the two ends of the shell slotted hole are wide, the middle of the shell slotted hole is narrow, and the shaft body is cylindrical.

The working principle is as follows: when a connecting shaft fixedly connected with the shaft body and extending out of the shell is subjected to radial impact load, the shaft is integrally inclined, the intersected surface moves, namely, a certain accommodated gap is formed after the front and the back of the side surface are inclined, and meanwhile, the sealing performance can be kept. When the bearing is used, the precision requirement of the part of the shaft, the shell and the bearing in contact is high, and the machining precision requirement of the output shaft is reduced because the bearing is not used.

Has the advantages that: compared with the prior art, the utility model, have following characteristics: the bearing can bear radial load or radial impact load when not supported by a radial bearing; a bearing is not needed, and the processing precision of the output shaft can be effectively reduced; the installation structure and the lubricating system of the transmission mechanism are simplified, the manufacturing cost of the transmission mechanism is effectively reduced, and the cost performance of the transmission mechanism is improved.
