Reduction gearbox with adjustable transmission ratio

Abstract

The invention discloses a reduction gearbox with the adjustable transmission ratio. The reduction gearbox comprises a box body as well as an output shaft and an input shaft which are arranged in the box body in parallel; a first gear and a second gear are arranged at the two ends, located in the box body, of the input shaft, a sliding sleeve is arranged on the output shaft in a sliding mode, a moving ring connected with the sliding sleeve in a sliding mode is arranged in the middle of the sliding sleeve, a third gear and a fourth gear are arranged at the two ends of the sliding sleeve, the first gear is connected with the third gear in a meshing mode, and the second gear is connected with the fourth gear in a meshing mode; a movable handle is rotationally arranged at the end, close to the output shaft, outside the box body, a movable frame is rotationally arranged in the middle of the sliding sleeve, and the other end of the movable frame is rotationally connected with the upper part of the movable handle. The reduction gearbox is simple in structure and easy to machine, manufacture and mount, the double-transmission-ratio design is adopted, selection can be conducted according to actual use conditions, and the requirements of various occasions can be met.

Description

technical field [0001] The invention relates to the technical field of reduction boxes, in particular to a reduction box with an adjustable transmission ratio. Background technique [0002] The reduction box is a relatively precise machine, and its purpose is to reduce the speed and increase the torque. By changing the number of gears, the modulus, the number of teeth, the helix angle, etc., the transmission ratio can be changed to achieve the purpose of reducing the speed and increasing the torque. In machinery manufacturing, gearboxes are widely required as transmission components between prime movers and working machines. Although there are many types of existing gearboxes, their structures are relatively complex, their volumes are large, their manufacturing costs are high, and their transmission efficiency is low. Low. And the transmission ratio of the existing reduction box cannot be adjusted according to the demand. When the transmission ratio needs to be changed, a ...

In machinery manufacturing, gearboxes are widely required as transmission components between prime movers and working machines. Although there are many types of existing gearboxes, their structures are relatively complex, their volumes are large, their manufacturing costs are high, and their transmission efficiency is low. Low

Moreover, the transmission ratio of the existing reduction box cannot be adjusted according to the demand. When the transmission ratio needs to be changed, a new reduction box can only be redesigned and manufactured, which not only costs a lot of money, but also prolongs the preparation time for equipment use.
