Embodiment Construction

[0030] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown, a shaft tooth protection sleeve includes a sleeve 1 and a handle shaft 3, the inner hole at one end of the sleeve 1 is sleeved on the outer cylindrical surface of one end of the handle shaft 3, and the wall thickness of the sleeve 1 is less than 0.1mm.

[0032] Further, the casing 1 and the handle shaft 3 are glued together with the rotor glue 2 .

[0033] Further, the bonding method is as follows: after the casing 1 and the handle shaft 3 are bonded together with the rotor glue 2 at room temperature, they are baked at a temperature ranging from 95 degrees Celsius to 105 degrees Celsius for 30 minutes to 35 minutes.

[0034] The rotor adhesive 2 is cured after the above high temperature, so as to firmly connect the sleeve 1 and the handle shaft 3 together, and the rotor adhesive 2 is a one-co...

Abstract

The invention provides a shaft tooth protective sleeve and a processing method. The shaft tooth protective sleeve comprises a sleeve pipe and a handle shaft, an inner hole of one end of the sleeve pipe is formed in the outer cylindrical surface of one end of the handle shaft in a sleeving mode, and the wall thickness of the sleeve pipe is less than 0.1 mm. The processing method of the sleeve pipecomprises the following steps that 1, a through hole is drilled in the axis of a solid cylinder material; 2, a wire penetrates through the through hole, and a central hole of the solid cylinder material is processed by slowly wiring to obtain the inner wall of the sleeve pipe; 3, the outer circle of the solid cylinder material is processed by slowly wiring to obtain the outer wall of the sleeve pipe; and 4, the wire starting point on the outer wall of the sleeve pipe is manually grinded to a smooth cylindrical surface. A product of the processing method has the advantages of high qualified rate, low cost and long service life.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a shaft tooth protection sleeve and a processing method. Background technique [0002] For some equipment, especially electromechanical equipment, some shafts need to be equipped with bearings. However, the shaft ends are often provided with shaft teeth that play a role in transmission. During the assembly process, the shaft teeth need to be protected by sleeves, and the sleeves are also equipped with handle shafts. In order to take the casing, the outer diameter of many shaft teeth is much smaller than the outer diameter of the shaft. Therefore, it is generally required that the wall thickness of the casing is less than 0.1mm to meet the working requirements. For such a thin-walled casing with a wall thickness of less than 0.1mm, the processing is very troublesome. One is high precision requirements, and the other is easy to deform. The existing processing method i...
