Description
Technical field
The present invention relates to a kind of auto parts and components field, specially a kind of automobile gear.
Background technology
The manufacture material and heat treatment process of gear have a great impact to the bearing capacity and dimensional weight of gear.20 generation
It recorded before the fifties, gear is mostly used carbon steel, uses steel alloy the sixties instead, and the seventies is mostly used case-hardened steel.According to hardness, the flank of tooth
Two kinds of the soft flank of tooth and Hardened gear face can be divided into, the gear capacity of the soft flank of tooth is relatively low, but manufacture is easier, and running-in is good,
It is chiefly used in the common mechanical of transmission size and weight without stringent limitation and limited production.Since in the gear of pairing, steamboat
Heavy load, therefore to keep the size working gear service life roughly equal, steamboat tooth face hardness is generally higher than bull wheel, Hardened gear face
The bearing capacity of gear is high, it is in gear fine cut and then to be quenched, the processing of surface hardening or carburizing and quenching, to improve
Hardness.But in heat treatment, gear inevitably results from deformation, thus must be ground after the heat treatment, grind or
Fine cut improves the precision of gear to eliminate the error generated by deformation.
Common gear after long-time use, due to will produce naked eyes when by rubbing with other movement rod pieces
The crackle being difficult to observe by can have an impact equipment moving, or even bring life threat, in addition, the not lubrication of lubricating oil,
It can aggravate the friction between movement parts, abrasion is caused to aggravate, service life substantially reduces.
Invention content
The purpose of the present invention is to provide a kind of automobile gears, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides the following technical solutions a kind of automobile gear, including wheel rim, the gear teeth, rolling
Pearl, keyway, carrying out flaw detection device and oilhole, the wheel rim outside is provided with the gear teeth, ball is provided on the inside of the wheel rim, described
It is provided with keyway on the inside of ball, the keyway inner wall is provided with carrying out flaw detection device, oilhole is provided on the wheel rim.
Further, the carrying out flaw detection device uses ultrasonic examination detection device, when ultrasonic wave is propagated in the medium,
The characteristic on not homogeneity interface with reflection such as encounters defect and then surpasses when the size of defect is equal to or more than ultrasonic wavelength
Sound wave reflects in defect, and carrying out flaw detection device can show back wave；As the size of defect is even less than wavelength
When, sound wave will cannot reflect around ray.
Further, the ball diameter is 0.8CM, and quantity is provided with 20, is double-row balls, can effectively improve
Working efficiency.
Further, the keyway length is 1CM.
Further, it is provided with oil pocket in the keyway, lubricating oil is stored in oil pocket, can be flowed out from oilhole,
The friction between ball can be effectively reduced, while can also take away the clast between ball, can also serve as the effect of coolant liquid.
Further, the wheel rim, the gear teeth, ball and keyway material therefor are hard alloy.
Compared with prior art, the beneficial effects of the invention are as follows：The newly-increased carrying out flaw detection device of this kind of automobile gear, is adopted
With ultrasonic listening principle, when sound wave is propagated in the medium, there is the characteristic of reflection on not homogeneity interface, such as encounter defect,
When the size of defect is equal to or more than ultrasonic wavelength, then ultrasonic wave reflects in defect, and carrying out flaw detection device can will be anti-
Ejected wave is shown, by the fracture detection of gear and position can be marked, and newly-increased oilhole can be by lubricating oil from oil
Hole is oozed out, and can be effectively reduced the friction between ball, while can also take away the clast between ball, can also be served as coolant liquid
Effect.
