Description
Technical Field
The utility model relates to a loader gearbox technical field, concretely relates to electric loader gearbox input shaft location structure.
Background
The gearbox is one of the core transmission components of the electrically controlled loader, and is a mechanism for changing the rotating speed and torque from the motor, and can change the transmission ratio of input and output in a fixed or stepping way. The input shaft is a shaft for power to enter the gearbox, the power enters the gearbox from the motor through the input shaft, and then the input shaft drives the input gear on the shaft to transmit the power to the output gear. In the prior art, the position of an external spline shaft of an input shaft is generally inserted into an internal spline sleeve of an output shaft of a motor to perform spline connection, so that power transmission is realized. The existing defects are that: the input shaft cantilever is too long, the disturbance degree is large during rotation, and the spline connection has a gap, so that the abrasion of the spline is accelerated in long-term use, the spline is damaged, and the power cannot be transmitted.
Disclosure of Invention
The utility model aims at overcoming above-mentioned defect, providing a quality is reliable, long service life's electric loader gearbox input shaft location structure, solve among the prior art because input shaft cantilever length, splined connection have the clearance cause the spline to damage the problem that leads to the unable transmission of power when using for a long time.
In order to achieve the purpose, the positioning structure of the input shaft of the gearbox of the electric loader comprises a motor end cover 1, a gearbox body 2, an input shaft 3 and an output shaft 4; an output shaft positioning spigot 42 is arranged in the output shaft 4, the output shaft 4 is arranged on the motor end cover 1 through a bearing, and a motor end cover positioning spigot 11 is arranged on the motor end cover 1; an input shaft positioning shaft 31 is arranged at one end of the input shaft 3, and the input shaft 3 is arranged on the gearbox body 2 through a bearing; a box body positioning step 21 is arranged on the gearbox box body 2, and the box body positioning step 21 is matched with the motor end cover positioning spigot 11 so as to improve the coaxiality of the mounted input shaft 3 and the mounted output shaft 4; the input shaft positioning shaft 31 is matched with the output shaft positioning spigot 42, so that the input shaft 3 is supported doubly, and the deflection caused by the length of a cantilever is avoided; an output shaft oil storage tank 41 is further arranged in the output shaft 4 to ensure the lubrication of the input shaft positioning shaft 31 and the output shaft positioning spigot 42.
The positioning structure of the input shaft of the gearbox of the electric loader with the structure has the following technical characteristics and beneficial effects:
1. the box body positioning step 21 is matched with the motor end cover positioning spigot 11, the coaxiality of the input shaft 3 and the output shaft 4 after installation is improved, and the product quality is guaranteed.
2. The input shaft positioning shaft 31 is matched with the output shaft positioning spigot 42, so that the input shaft 3 is doubly supported, the deflection caused by the length of a cantilever is avoided, and the product quality is greatly improved.
3. An output shaft oil storage tank 41 is arranged in the output shaft 4, so that the lubrication of the input shaft positioning shaft 31 and the output shaft positioning spigot 42 is improved, dry grinding is avoided when the motor rotates forwards and backwards, and the product quality is greatly improved.
The utility model discloses electric loader gearbox input shaft location structure has solved prior art because input shaft cantilever length, and the degree of disturbance is great during the rotation to spline connection has the clearance, can accelerate the wearing and tearing of spline in long-term the use, thereby causes the spline to damage the problem that leads to the unable transmission of power.
