Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to tightly connected automobile transmission gears. Background Art

[0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in a fixed or divided manner. It is also called a gearbox. The gearbox consists of a speed transmission mechanism and a speed control mechanism. The main function of the speed transmission mechanism is to change the value and direction of the torque and speed; the main function of the control mechanism is to control the transmission mechanism to achieve the change of the transmission ratio of the transmission, that is, to achieve gear shifting to achieve speed and torque change. Most transmission mechanisms use ordinary gear transmission, and some use planetary gear transmission. Ordinary gear transmission speed change mechanisms generally use sliding gears and synchronizers.

[0003] The utility model patent application document with publication number "CN215257701U" discloses an automobile gearbox gear. The automobile gearbox gear includes a gear body. An axial hole is processed in the middle of the gear body. A keyway is processed at the edge of the axial hole to facilitate the installation of a flat key. An adjusting component is installed on the gear body. A clamping component is installed on the adjusting component to clamp the rotating shaft. A guide component is installed on the gear body. The clamping component is connected to the guide component. The gear body can be fixed on the rotating shaft through the flat key. The adjusting component is rotated to drive the clamping component to move so that the clamping component is in close contact with the surface of the rotating shaft, thereby playing a role of auxiliary support, so that the gear body and the rotating shaft are more closely engaged and the gear body is prevented from sliding along the rotating shaft. The arc groove on the clamping block fits with the surface of the rotating shaft to clamp the rotating shaft. By setting an anti-slip protrusion, the friction force can be increased, so that the clamping block and the rotating shaft are in closer contact, thereby improving the stability of the gear body.

[0004] The automobile transmission gear disclosed in the above document has the following defects: after long-term use, the gear of this technical solution cannot be used after being worn to a certain extent, so the entire gear needs to be replaced, and the use cost is relatively high.

[0005] It can be seen from this that the existing automobile transmission gears do not have a structure that reduces the cost of use, and it is necessary to improve the existing deficiencies and provide automobile transmission gears with tight connections. Utility Model Content
