Embodiment Construction

[0013] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0014] combine figure 1 , a low-speed machine multifunctional connecting rod bolt disclosed by the present invention, comprising a bolt head 1 and a screw rod 7, the bolt head 1 and the screw rod 7 are integrated, the bolt head 1 adopts a hexagonal head structure with a flange surface, and the screw rod 7 The upper and middle parts are two raised sections 2, and the lower part of the screw is a threaded section 4; the bolt head 1 in the bolt and the two raised sections in the upper and middle part of the screw 7 of the screw are arranged with six rows of circular particles for positioning 3. These protrusions are made of rubber, and then put on the protrusion section. The joint of the bolt head 1 of the screw rod and the screw rod 7 has rounded corners. There is a cross oil suction groove 5 under the thread section 4, and the cross oil suction groove 5 is used fo...

Abstract

The invention aims at providing a low-speed machine multifunctional connecting rod bolt which comprises a bolt head and a screw rod. The screw rod is connected to the bottom of the bolt head, the middle of the screw rod is provided with two sections of protrusions, the protrusions are provided with circular granules, the lower portion of the screw rod is provided with a thread section, a crossed oil suction groove where oil suction materials are installed is formed below the thread section, the lower end of the oil suction materials is a cylinder, the top of the cylinder is provided with a crossed body connected with the cylinder, and the crossed body is embedded into the crossed oil suction groove. The connecting rod bolt is simple and reasonable in structure, and the connection rod boltcan be better applied to connecting of connecting rod components through high looseness resistance of a hexagonal flange face bolt head, the positioning function of the circular grains on the protrusion sections and the oil suction characteristics of specific oil suction materials.

Description

technical field [0001] The invention relates to a connecting part of a diesel engine, specifically a connecting rod bolt. Background technique [0002] As an important part of the connecting rod system of the low-speed machine, the connecting rod bolt is mainly used to connect the large end cover of the connecting rod, the bearing bush of the large end of the connecting rod and the rod body, and bear the alternating load such as tension and bending of the connecting rod system and the lateral vibration load , the force is more complicated. Due to the harsh working environment of the connecting rod bolts, sometimes the contact between the bolt head and the large end cover of the connecting rod or the contact between the screw rod and the bolt hole becomes loose due to the force or vibration of the machine body, which affects its fastening effect. If the connecting rod bolt fails and flies out of the screw hole, it will cause serious damage to the low-speed machine in operati...
