Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a novel transmission adjustment device. Background Art

[0002] Mechanical transmission is widely used in mechanical engineering, mainly referring to the transmission of power and motion by mechanical means. It is divided into two categories: one is friction transmission that transmits power by friction between mechanical parts, and the other is meshing transmission that transmits power or motion by meshing between the active part and the driven part or with the help of the meshing of the intermediate part.

[0003] For example, a spindle transmission speed adjustment device disclosed in the authorization announcement number CN201047423Y is provided with a housing, an oblique guide hole is formed around the housing, and a transmission shaft and a connecting shaft are pivotally arranged inside and at the rear end respectively. The transmission shaft forms a planetary gear structure that meshes with the connecting shaft at the rear end, and a speed change middle sleeve is sleeved around the transmission shaft. The speed change middle sleeve cooperates with the planetary gear structure and the connecting shaft to form a sun gear. A ring slide is formed around the speed change middle sleeve and a push block is embedded. A speed change ring is sleeved around the housing, and a push rod passing through the guide hole is combined between the speed change ring and the push block. When the utility model is used, the speed change ring is rotated and the speed change middle sleeve is linked to move forward and backward in two stages, so that the sun gear can choose whether to directly mesh with the connecting shaft or not, so as to achieve the two-stage transmission effect of equal speed and deceleration. However, the structure of the utility model is relatively complex, and the later maintenance and repair operations are cumbersome. For this reason, we propose a new transmission adjustment device, which simplifies the transmission adjustment structure and also improves the convenience of later maintenance operations, thereby improving the practicality of the device.
