Abstract
The invention discloses a car transmission shaft supporting base treated by nitriding. The car transmission shaft supporting base comprises a body and a nitriding process, wherein the body is of a cylindrical structure; the main body center is set as a hollow cylinder structure; upper and lower parts of the hollow cylinder structure are respectively equipped with blocking ring slots which are respectively an upper blocking ring slot and a lower blocking ring slot; six circular through holes are uniformly distributed in the middle of the main body; a circular-ring shaped groove is arranged in the middle of the outer ring; a cylindrical base is arranged on the bottom of the main body; and eight cylindrical fixed through holes are uniformly distributed above the cylindrical base; the nitriding treatment comprises the following steps of: removing oil by a gas before nitriding treatment; then, carrying out sand blasting treatment onto the surface by using aluminum oxide powder, and then placing treated components in a nitriding furnace, and heating after sealing a furnace cover. Being treated by nitriding, the car transmission shaft supporting base disclosed by the invention has characteristics of being excellent in wearing resistance, fatigue resistance, corrosion resistance and high temperature resistance.
Description
Technical field
The present invention relates to a kind of engineering goods, is a kind of vehicle transmission shaft stool of via nitride processing specifically.
Background technology
Some vehicle transmission shaft stools on existing market, due to the truck drive shaft of ining succession, frequency of utilization is very high, it is easy to occur wearing and tearing and fracture, is especially exposed in air, is vulnerable to the erosion of air, cause transmission shaft to produce gap, in vehicle traveling process, cause danger.
Summary of the invention
The invention provides a kind of vehicle transmission shaft stool of via nitride processing.
The object of the invention is to solve more existing vehicle transmission shaft stools, due to the truck drive shaft of ining succession, frequency of utilization is very high, it is easy to occur wearing and tearing and fracture, especially be exposed in air, be vulnerable to the erosion of air, cause transmission shaft to produce gap, the problem of causing danger in vehicle traveling process.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vehicle transmission shaft stool of via nitride processing, comprise the process of body and nitriding treatment, described body is made as cylindrical structure, body center is made as hollow cylinder structure, it is respectively provided with an annular groove up and down, be respectively annular groove and lower annular groove, uniform six circular through holes in the middle of described body, in the middle of its outer ring, be provided with the groove of annular, described body bottom is provided with a columniform base, its uniform eight columniform fixed vias in top, described nitriding treatment comprises, first nitriding deoils with gas before processing, then use aluminum oxide powder that sandblasting is done in surface, then more processed part is placed in to nitriding furnace, and will after bell sealing, can heat, but before being heated to 150 DEG C, must do excluding air work in stove, after nitriding completes, heating power supply is closed, make furnace temperature reduce approximately 50 DEG C, then after the flow of ammonia being doubled, start breakdown heat exchanger, wait the ammonia importing in stove stable after, the flow that can reduce ammonia is to keeping in stove till malleation, in the time that furnace temperature drops to below 150 DEG C, can breakdown bell after importing air or nitrogen.The present invention is through having excellent wear resistance, resistance to fatigue, solidity to corrosion and resistant to elevated temperatures characteristic after nitriding treatment.
Brief description of the drawings
Fig. 1 is side-view of the present invention.
Fig. 2 is vertical 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 the process of body 1 and nitriding treatment, described body 1 is made as cylindrical structure, body 1 center is made as hollow cylinder structure 3, it is respectively provided with an annular groove up and down, be respectively annular groove 8 and lower annular groove 4, uniform six circular through holes 9 in the middle of described body 1, in the middle of its outer ring 7, be provided with the groove 6 of annular, described body 1 bottom is provided with a columniform base 5, its uniform eight columniform fixed vias 2 in top, described nitriding treatment comprises, first nitriding deoils with gas before processing, then use aluminum oxide powder that sandblasting is done in surface, then more processed part is placed in to nitriding furnace, and will after bell sealing, can heat, but before being heated to 150 DEG C, must do excluding air work in stove, after nitriding completes, heating power supply is closed, make furnace temperature reduce approximately 50 DEG C, then after the flow of ammonia being doubled, start breakdown heat exchanger, wait the ammonia importing in stove stable after, the flow that can reduce ammonia is to keeping in stove till malleation, in the time that furnace temperature drops to below 150 DEG C, can breakdown bell after importing air or nitrogen.The present invention is through having excellent wear resistance, resistance to fatigue, solidity to corrosion and resistant to elevated temperatures characteristic after nitriding treatment.
