Abstract

The invention relates to a gear chamfering method. According to the gear chamfering method, in a gear shifting meshing process, a gear easily slides in the chamfering process, and the gear cannot be bruised. According to the method, the gear end of a common turning lathe is turned into a small-angle corner, a common chamfering machine is used for conducting sharp corner chamfering on the tooth end of the gear, in the sharp corner chamfering, a user should pay attention to reversing a small plane in the middle of the tooth end, and an acute angle is formed between the sharp corner face and a gradual-open line tooth face. After gear heat treatment, a special grinding tool is used for chamfering the acute angle into a round angle. The method has the advantages that the gear easily slides into the chamfering process in the shifting process, and the gear cannot be bruised.

Description

A kind of gear chamfering method

Technical field

The present invention relates to a kind of gear chamfering method, belong to machinery manufacturing technology field.

Background technology

Existing gear all need to carry out chamfering in the tooth ends of gear in the time of speed change, be beneficial to the engagement of gear, traditional end relief has down wedge angle and two kinds of modes of rounding, two kinds of chamfering modes have obvious deficiency, when the gear shift of falling wedge angle, easily slip into, but can make gear damage, touch hair, the rounding gear of can not damaging, but be not easy to slip into when gear shift.

Summary of the invention

The object of the invention is to, a kind of gear chamfering method is provided, while making gear shift engagement, both easily slipped into, can not make again gear damage.

The object of the present invention is achieved like this: geared end car is become to a low-angle angle on engine lathe, gear increment is fallen to wedge angle with common beveler, in the time of falling wedge angle, is noted in the middle of increment, staying next little plane, and wedge angle face and involute flank can form acute angle.After gear heat treatment, with special grinding tool, acute angle is changed into fillet.

Owing to adopting technique scheme, advantage and good effect that the present invention has are: gear easily slips in the time of gear shift, can not make again gear damage.

Brief description of the drawings

Fig. 1 is that the gear teeth fall the schematic diagram of wedge angle

Fig. 2 is the top view of Fig. 1

Fig. 3 is the schematic diagram that the gear teeth fall after acute angle

Fig. 4 is Fig. 3 top view.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, structure of the present invention is further elaborated.

As shown in Figure 1 and Figure 2, geared end car is become to one 7 degree angle on engine lathe, gear increment is fallen to wedge angle with common beveler, in the time of falling wedge angle, notes staying the facet of the next wide 0.2Mn of being about (Mn is module) in the middle of increment, and wedge angle face and involute flank can form acute angle.

As shown in Figure 3, Figure 4, after gear heat treatment, with special grinding tool, the acute angle forming in operation is above changed into 45 degree fillets, the wide 0.2Mn of being about (Mn is module) of arc surface.

It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is modified or is equal to replacement, do not depart from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.

Claims

1. a gear chamfering method, geared end car is become to a low-angle angle on engine lathe, gear increment is fallen to wedge angle with common beveler, in the time of falling wedge angle, is noted in the middle of increment, staying next little plane, and wedge angle face and involute flank can form acute angle.After gear heat treatment, with special grinding tool, acute angle is changed into fillet.
