Highly stable and adjustable double-end face gear transmission mechanism

Abstract

The invention discloses a highly stable and adjustable double-end face gear transmission mechanism comprising an input part, a differential mechanism, and two output shafts which are coaxially fixed on two half axle gears of the differential mechanism one-to-one. The input part is drivingly connected with a differential body of the differential mechanism through two parallel and symmetric bevel gears and a double-end face bevel gear which is engaged with the two bevel gears. A housing of the differential mechanism is provided with a limiting seat for radially limiting the two bevel gears; and the length of the output shafts is adjustable. In the highly stable and adjustable double-end face gear transmission mechanism, the input part is drivingly connected with the differential body of the differential mechanism through the two parallel and symmetric bevel gears and the double-end face bevel gear which is engaged with the two bevel gears, and axial component forces generated by the two bevel gears to the double-end face bevel gear counteract with one another, thereby ensuring that the axial stress of the differential body is balanced, and increasing the structural stability of a drive wheel and corresponding axle of the transmission mechanism between the input part and the differential mechanism, and accordingly being advantageous to the running of the differential mechanism, as well as extending the service life.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a high-stability adjustable double-face gear transmission mechanism. Background technique [0002] Differentials are often used in vehicles to enable the left and right drive wheels to rotate at different speeds. They are mainly composed of left and right side shaft gears, two planetary gears, casings, planetary wheel shafts and a differential body as a planetary carrier. When the car turns When driving or driving on uneven roads, make the left and right wheels roll at different speeds, that is, ensure the pure rolling motion of the driving wheels on both sides. In the prior art, the differential body of the differential and the input shaft are generally connected through a bevel gear pair, and affected by the pressure angle of the gear pair, the driven wheel of the bevel gear pair will receive axial thrust and transfer the force It is transmitted to the differential body, resulting in an ...

[0002] Differentials are often used in vehicles to enable the left and right drive wheels to rotate at different speeds. They are mainly composed of left and right side shaft gears, two planetary gears, casings, planetary wheel shafts and a differential body as a planetary carrier. When the car turns When driving or driving on uneven roads, make the left and right wheels roll at different speeds, that is, ensure the pure rolling motion of the driving wheels on both sides. In the prior art, the differential body of the differential and the input shaft are generally connected through a bevel gear pair, and affected by the pressure angle of the gear pair, the driven wheel of the bevel gear pair will receive axial thrust and transfer the force It is transmitted to the differential body, resulting in an unbalanced axial force on the differential body, and at the same time, the input shaft of the differential device is subjected to a tangential reaction force, resulting in extremely poor stability, which is not conducive to the operation of the differential mechanism and affects the service life; the existing In the technology, agricultural vehicles cannot adjust the distance between the left and right wheels according to the ridge width of the field, so when the ridge width of the field is not standardized, it is not conducive to the vehicle to drive in the field
