Transmission with adjustable transmission pitch

Abstract

The invention discloses a transmission device capable of regulating the transmission distance, which comprises a section of driving cylinder shaft, at least one section of driving special-shaped shaft, a retainer and second transmission shafts; the driving cylinder shaft is connected with a power source by a power input mechanism; a first stepped shaft is sleeved on the driving special-shaped shaft, and the stepped shaft is connected with a load by a transmission mechanism; at least one of the second transmission shafts is connected with the driving special-shaped shaft by the transmission mechanism; the retainer is connected with the first stepped shaft and the second transmission shafts, so that the axis movement of the first stepped shaft is carried out along the driving special-shaped shaft along with the movement of the second transmission shafts; and the relative distance between the second transmission shafts and the power input mechanism is changed by changing the relative position of the first stepped shaft sleeved on the driving special-shaped shaft.

Description

technical field [0001] The invention relates to mechanical transmission, in particular to a transmission device with adjustable transmission distance. Background technique [0002] Mechanical transmission is widely used in mechanical engineering, mainly referring to the use of mechanical means to transmit power and motion; the active part connected to the power source, the middle part connected to the active part and the middle part, and the driven part connected to the load are common mechanical transmission devices Basic composition structure. A common type of mechanical transmission is that the power source relies on the input power of the active part, and relies on a mechanism that transmits power or motion as a transmission device to transmit power or motion to the driven part, thereby transmitting the motion or power to the load. When the active part relies on the transmission device to transmit power or motion to the driven part, the power transmission parts are gene...

AI Technical Summary

Problems solved by technology

[0003] In the mechanical transmission device of the prior art, the relative distance between the active part and the driven part is generally fixed; if the structure of the transmission device is not changed, the relative distance between the active part and the driven part of the transmission device cannot be changed. The relative distance between where the source is connected on the transmission and where the load is connected on the transmission cannot be changed

When the relative distance between the load and the power source changes, or in the case of relative motion between the load and the power source during transmission, it is difficult for the existing mechanical transmission device to meet the transmission requirements of the distance change
