Description
Technical field
The utility model relates to field of mechanical technique, is specially a kind of jack shaft one grade of gear.
Background technique
Gear is the part belonged in auto parts and components, be mainly used for transferring power effect, and due to the stable performance of gear transmission, long service life, operate meticulous, efficiency advantages of higher, the parent that gear obtains everybody looks at, and the gear on market exists very large reason in production, production process is complicated and make gear in fine degree, not reach required requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of jack shaft one grade of gear, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of jack shaft one grade of gear, comprise circular groove, the outside of described circular groove is provided with a circle driving gear, the upper surface of described circular groove is provided with lightening hole, the quantity that the upper surface in the internal projection portion of described circular groove and lower surface are respectively equipped with oil groove is four, and the bottom in the internal projection portion of described circular groove is provided with synchronous cone, and the middle part of described circular groove is provided with unthreaded hole.
Preferably, described lightening hole and circular groove adopt one-body molded, and the quantity of described lightening hole is ten.
Preferably, the two ends of described circular groove are provided with pattern draft, and use round-corner transition.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by the basis of former jack shaft one grade of gear, mode of in the circular groove at two ends a 10 lightening hole heat being rushed is shaping, simultaneously by increasing circular groove pattern draft, by oil groove forging molding, the lightening hole and the oil groove that achieve jack shaft one grade of gear machine through forging and heat punching, and circular groove once-through when forging puts in place, due to once-through, inside parts fiber is continuous, fine microstructures, mechanical property is improved, reduce follow-up machining process amount, cost of production is low.
