Embodiment Construction

[0009] Such as figure 1 As shown, the present invention is connected with a flange head 2 at one end of the circular cylinder body 1, and an annular spline groove 3 is arranged on the outer circumference of the junction of the circular cylinder body 1 and the flange head 2, and the internal thread 4 is located at On the wall of the inner hole of the circular cylinder 1 and the flange head 2. Through the above settings, the unique structure and internal technical indicators of the present invention guarantee the performance of the entire engine, and the special shape is adapted to the special requirements of the connecting rod, which will not loosen under the action of alternating force and better meet the torque requirements. The precision requirement of the internal thread 4 can better play a locking effect.

Abstract

The invention discloses a connecting rod nut. The connecting rod nut is characterized in that a flange head is connected to one end of an annular cylinder body, a ring-shaped spline slot is formed in the circumference of the joint of the annular cylinder body and the flange head, and internal threads are formed in the wall of an inner hole of the annular cylinder body and the flange head. Through the arrangement, the connecting rod nut provided by the invention is made of high quality structural alloy steel, and both the mechanical property and the surface treatment meet the use requirements.

Description

technical field [0001] The invention relates to a nut, in particular to a connecting rod nut for an engine. Background technique [0002] The engine connecting rod nut has a special structure, with splines on the outside and threads on the inside. It is used to lock the connecting rod bolts and is an important component of the connecting rod. Connecting rod nuts used to be imported from abroad, but there are many inconveniences in foreign imports: first, the supply is not timely, second, the torque quality is difficult to guarantee, and third, the price is expensive. Contents of the invention [0003] The object of the present invention is to provide a connecting rod nut for an engine. [0004] In order to achieve the above object, the present invention is connected with a flange head at one end of the circular cylinder, an annular spline groove is arranged on the outer circumference of the connection between the circular cylinder and the flange head, and the internal thr...
