Benefits of technology

"The present invention provides a torque adjusting mechanism that can control the torque using the coupling interface between the shaft and the main body of the mechanism. The mechanism is assembled from components that can easily be taken apart. The adjusting base has a torque adjusting mechanism with good coaxiality to accurately adjust the orientation of a supported apparatus. The mechanism includes a shaft, a main body, and an adjusting device. The adjusting device includes an adjusting hole, an adjusting button, and an elastic body. The elastic body provides a predetermined torque between the shaft and the main body before the adjusting button is moved. The adjusting button presses on the elastic body to increase the torque between the shaft and the main body when moved towards the shaft."

Problems solved by technology

This kind of torque adjusting method is very hard to provide a stable torque, for the contact area between the two pivoting devices and the head of bolt and the nut or the deformed rivet head.
When using the nut and bolt as the fixing device, they may become more loose or tight as the pivoting devices rotate because of the friction between them.
Therefore, it is hard to maintain a stable torque.
Once a predetermined torque is reached, it is hard to be loosened.
If one wants to separate the two pivoting devices, the rivet has to be destroyed.
The destroyed rivet can no longer be used in the torque adjusting mechanism.
Moreover, if the two pivoting devices have a different hole size than the fixing device, they cannot rotate about the same center.
It is then very difficult to adjust the orientations of the devices with high precision.

Embodiment Construction

[0023] The present invention is apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

[0024] As shown in FIGS. 1A, 1B, 2, and 3, the disclosed torque adjusting mechanism includes a shaft 100, a main body 200, and an adjusting device 400.

[0025] The main body 200 has a circular wall, and the central portion of the circular wall is a circular through hole 210, the diameter of the circular through hole 210 is slightly larger than that of the shaft 100, for coupling to the shaft 100.

[0026] The adjusting device 400 disposed on the main body 200 is used to adjust the torque between the main body 200 and the shaft 100. The adjusting device 400 includes an adjusting hole 410, an adjusting button 420, and an elastic body 430.

[0027] The adjusting hole 410 is perpendicular to the through hole 210 and penetrates the circular wall of the main body 200. The adjusting button 420 coupl...

Abstract

A torque adjusting mechanism including a shaft, a main body, and an adjusting device is provided. The main body has a circular wall and a through hole disposed therein for coupling to the shaft. The adjusting device disposed on the main body includes an adjusting hole, an adjusting button and an elastic body disposed inside the adjusting hole. The adjusting hole is perpendicular to the through hole and penetrates the circular wall. The adjusting button coupled to the adjusting hole can be adjusted along the adjusting hole. One end of the elastic body contacts with the adjusting button and the other end presses on the shaft. Therefore, the elastic body can provide a predetermined torque between the shaft and the main body and further increase the torque between the main body and the shaft.

Description

RELATED APPLICATIONS [0001] The present application is based on, and claims priority from, Taiwan Application Serial Number 94201025, filed Jan. 19, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND [0002] 1. Field of the Invention [0003] The invention relates to a torque adjusting mechanism and, in particular, to an elastic torque adjusting mechanism. [0004] 2. Description of the Related Art [0005] To adjust the torque between two devices rotating with respect to each other and coupled by a shaft, a torque adjusting mechanism is often provided between the shaft and the pivoting devices. The conventional torque adjusting mechanism usually is a fixing device penetrating through the pivoting devices. The fixing device, for example, has a set of nut and bolt or a rivet. The method of adjusting the torque is to adjust the tightness between the nut and bolt or the depth of the rivet. This kind of torque adjusting method is very hard to p...
