Abstract

The invention discloses an automobile speed reducer cover and a thermal processing technology thereof. The automobile speed reducer cover comprises a body. The thermal processing technology is provided with a disc-shaped structure. A circular end face is arranged at the upper portion of the body. Four fixing holes are formed in the end face and include the first fixing hole, the second fixing hole, the third fixing hole and the fourth fixing hole. Two vent holes are formed in the front side and the back side of the body respectively and include the first vent hole and the second vent hole, and a circular through hole is formed in the middle of the body. An annular check ring is arranged at the lower portion of the body. The thermal processing technology of the automobile speed reducer cover is characterized in that after austenitizing is achieved through heating, the automobile speed reducer cover is immersed into an appropriate quenching medium to be rapidly cooled. The automobile speed reducer cover has high enough tensile strength to resist stretching, tensile failure, thread slipping and abrasion, has high fatigue resistance and impact toughness, can resist fatigue and impact fracture and can be applied to an automobile speed reducer very well.

Description

A kind of car deceleration device outer cover and heat treatment process thereof
Technical field
The present invention relates to a kind of engineering goods, specifically a kind of car deceleration device outer cover and heat treatment process thereof.
Background technique
Some car deceleration device outer covers on existing market, cannot resist elongation, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, can not well apply in car deceleration device.
Summary of the invention
The invention provides a kind of car deceleration device outer cover and heat treatment process thereof.
The object of the invention is to solve more existing car deceleration device outer covers, there is no sufficiently high tensile strength, elongation cannot be resisted, break, slide fastener and wearing and tearing, and fatigue resistance and impact toughness also not high enough, cannot resisting fatigue and impact fracture, well can not apply to the problem in car deceleration device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of car deceleration device outer cover and heat treatment process thereof, comprise body and heat treated process, described body is set to disc-shaped structure, a circular end face is provided with above it, described end face is provided with four fixed holes, be respectively the first fixed hole, second fixed hole, 3rd fixed hole and the 4th fixed hole, before and after it, both sides are respectively provided with a vent, be respectively the first vent and the second vent, its centre is provided with a circular through hole, an annular back-up ring is provided with below described body, its heat treatment process feature immerses after being heated to austenitizing in suitable quenching medium with speed cooling faster.
Described heat treatment process, when selective quenching medium, first should ensure enough cooling capacities, namely selects the quenching medium that cooling capacity is high, also should prevent distortion and hardening break.
The present invention has sufficiently high tensile strength, to resist elongation, breaks, slide fastener and wearing and tearing, and has higher fatigue resistance and impact toughness, can resisting fatigue and impact fracture, can well apply in car deceleration device.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention.
Fig. 2 is side view of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in the figure, the present invention includes body 4 and heat treated process, described body 4 is set to disc-shaped structure, a circular end face 1 is provided with above it, described end face 1 is provided with four fixed holes, be respectively the first fixed hole 9, second fixed hole 2, 3rd fixed hole 6 and the 4th fixed hole 8, before and after it, both sides are respectively provided with a vent, be respectively the first vent 7 and the second vent 10, its centre is provided with a circular through hole 5, an annular back-up ring 3 is provided with below described body 4, its heat treatment process feature immerses after being heated to austenitizing in suitable quenching medium with speed cooling faster.
Described heat treatment process, when selective quenching medium, first should ensure enough cooling capacities, namely selects the quenching medium that cooling capacity is high, also should prevent distortion and hardening break.
The present invention has sufficiently high tensile strength, to resist elongation, breaks, slide fastener and wearing and tearing, and has higher fatigue resistance and impact toughness, can resisting fatigue and impact fracture, can well apply in car deceleration device.
