Problems solved by technology

Because it cooperates with the drive shaft of the accessory pump through the tapered surface, and the nut is pressed and directly connected, so the axial force will be directly loaded on the drive shaft of the accessory pump, thus affecting the normal operation of the accessory pump

Abstract

Disclosed is an adjustable thrust structure for balancing axial force of a gear. An oil groove is arranged on a thrust washer (2), a supporting seat (6) is fixed on a box (3) through a screw (5), the thrust washer (2) is installed over the supporting seat (6), an accessory pump drive shaft (1) is connected with a helical gear (7), a gland nut (4) is connected with a tapered shaft of the accessory pump drive shaft (1), and the other end of the accessory pump drive shaft (1) is connected with a pump body. According to the adjustable thrust structure, thrust positions of the axial force can be adjusted flexibly through adjustment of the thickness of the thrust washer (2), therefore the axial force is balanced at different positions, poor phenomena on an accessory pump due to the present of the axial force are eliminated, using requirement for the complete machine are met, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of balancing the axial force of gears, and in particular relates to an adjustable thrust structure for balancing the axial force of gears. Background technique [0002] Known gear transmission is the most general transmission mode for engine accessory transmissions such as water pumps, oil pumps, and variable displacement pumps. The helical gear transmission is more stable and stronger than the spur gear transmission. In order to ensure the reliability and compactness of the structure and the smoothness of the transmission, the helical gear transmission has better advantages. However, the helical gear transmission will generate a certain axial force. For the drive shaft system of the accessory pump, if there is no axial thrust structure, the axial force will be directly transmitted to the drive shaft of the accessory pump through the gear connected with the drive shaft. If the accessory is greatly affecte...
