Problems solved by technology

[0003] In the existing gearbox, two gearboxes are connected in series, and the position of the input shaft of the second gearbox is unreasonably designed, resulting in shaft breakage. When the second gearbox bears a large load when reversing, the reverse gear teeth are knocked out. The fried shell only has reverse gear function in the second gearbox, and cannot restore the original speed ratio, making it drive slowly, which has no economic benefits. Because the second gearbox is bulky, complicated to install, and consumes more materials, it leads to an increase in manufacturing costs.

Abstract

The invention discloses a combined gearbox. The combined gearbox comprises a first box body, wherein the center of the top of the first box body is connected with an output shaft, the center of the bottom of the first box body is connected with an input shaft, the top of the input shaft is in clamped connection with the bottom of the output shaft, the outer surface of the input shaft is sleeved with a high-speed gear, and the outer surface of the output shaft is sleeved with a sliding sleeve. According to the combined gearbox, the problem of shaft breakage caused by unreasonable position design of an input shaft of a second gearbox body is avoided, and the problem of tooth beating is solved to a great extent. The problems that the second gearbox body only has a reverse gear function, the driving speed is low, and labor hours are wasted are solved, the overall size of the gearbox is changed, and the combined gearbox solves the problem of gearbox shaft breakage and tooth breaking to a great extent. The gearbox has double speed ratios and can advance and retreat, the speed can be high, labor hours are saved, labor is saved, the speed can also be low, stable beam conveying is achieved,the overall size is reduced, material consumption is reduced, and the cost is reduced. The beam conveying gearbox truly saves time, labor and money.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a combined gearbox. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of torque converter, planetary gear, hydraulic pitch change system and hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. [0003] In the existing gearbox, two gearboxes are connected in series, and the position of the input shaft of the second gearbox is unreasonably designed, resulting in shaft breakage. When the second gearbox bears a large load when reversing, the reverse gear teeth are knocked out. The fried shell only has reverse gear function in the second gearbox, and cannot restore the original speed ...
