Problems solved by technology

[0002] In gear transmission or worm gear transmission, due to the existence of machining accuracy and assembly accuracy, it is difficult to ensure that the center distance meets the design requirements, thus affecting the transmission accuracy
[0003] However, it is difficult to adjust the center distance between shafts in existing gear transmission or worm gear transmission.
Due to processing errors, the meshing gap increases or cannot be meshed normally, which affects the transmission efficiency and reduces the transmission accuracy of the equipment.

Embodiment Construction

[0012] Such as figure 1 As shown, the present invention provides a center distance adjustment mechanism between shafts, which includes a driving shaft 1 and a driven shaft 2, and the two ends of the driving shaft are respectively installed on two driving bearing seats 3, 4, as shown in figure 2 As shown, the inner surfaces of the two active bearing seats are non-concentric cylindrical surfaces, and there is an eccentricity δ between them.

[0013] Such as figure 1 As shown, the inter-shaft center distance adjustment mechanism is installed in the box body 5 .

[0014] In gear transmission or worm gear transmission, due to the existence of machining accuracy and assembly accuracy, it is difficult to ensure that the center distance meets the design requirements, thus affecting the transmission accuracy. The adjusting mechanism of the center distance between shafts of the present invention can realize micro-adjustment of the center distance, compensate for processing errors, an...

Abstract

The invention discloses an inter-shaft central distance adjusting mechanism which comprises a driving shaft and a driven shaft. The two ends of the driving shaft are installed on two driving bearing pedestals respectively. The inner surfaces of the two driving bearing pedestals are non-concentric cylindrical surfaces. The eccentricity exists between the two driving bearing pedestals. By means of the inter-shaft central distance adjusting mechanism, the central distance can be slightly adjusted, the machining errors are reduced, and the assembling accuracy is adjusted.

Description

technical field [0001] The invention relates to a mechanism for adjusting the center distance between shafts. Background technique [0002] In gear transmission or worm gear transmission, due to the existence of machining accuracy and assembly accuracy, it is difficult to ensure that the center distance meets the design requirements, thus affecting the transmission accuracy. [0003] However, it is difficult to adjust the center distance between shafts in the existing gear transmission or worm gear transmission. Due to processing errors, the meshing gap increases or cannot be meshed normally, which affects the transmission efficiency and reduces the transmission accuracy of the equipment. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a center distance adjustment mechanism between shafts, which can realize micro-adjustment of the center distance, compensate for processi...
