Problems solved by technology

The translational control of the sprocket is often separated from the chain drive itself, and a tensioner is also required, which makes the position adjustment of the sprocket require a lot of auxiliary parts and power, which greatly increases the cost and instability of the chain drive

Embodiment Construction

[0093] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0094]A semi-circulating ball type sprocket position adjustment device, comprising: a first wheel assembly 1, a second wheel assembly 2, a third wheel assembly 3, a transmission chain 4, an adjustment chain 5, a base plate 6, a transmission motor 7, Adjust the motor 8 and the steel ball 905.

[0095] like figure 1 As shown, the first wheel assembly 1 , the second wheel assembly 2 and the third wheel assembly 3 are all mounted on the base plate 6 .

[0096] The bottom plate 6 is provided with a movement track, and the movement track is a part between the horizontal heights of two focal points of the ellipse.

[0097] Preferably, the ellipse has a focal length of 400mm and a long axis of 800mm.

[0098] like Figure 3 to Figure 21 As shown, the first wheel assembly 1 includes: a first wheel 101 , a first wheel axle 102 , a first transmission...

Abstract

The invention belongs to the technical field of mechanical transmission devices, and relates to a semi-cycle ball type chain wheel position adjusting device and method. The device comprises a first wheel assembly, a second wheel assembly, a third wheel assembly, a transmission chain, an adjusting chain, a bottom plate, a transmission motor, an adjusting motor and a steel ball, position adjustment of the chain wheels and chain transmission are integrated into one set of device, so that the occupied space of the device is effectively reduced; the track of the third transmission chain wheel is oval, and it is guaranteed that the transmission chain is always tightened in the position adjusting process of the third transmission chain wheel. The rigid action among the steel balls, the third wheel first track and the third wheel second track can ensure the stability and precision of position adjustment of the chain wheel; different motors are adopted for position adjustment of the chain wheel and chain transmission, transmission routes of the motors are completely separated, it can be guaranteed that position adjustment of the chain wheel and chain transmission are independently controlled to operate, a controller can be externally connected to enable the two actions to operate in a coordinated mode, and the use scene of the device is greatly enriched.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission devices, and relates to a position adjusting device and an adjusting method for a semi-circulating ball sprocket. Background technique [0002] Compared with belt drive, chain drive has no elastic sliding and slipping phenomenon, the average transmission ratio is accurate, the work is reliable, and the efficiency is high; the transmission power is large, the overload capacity is strong, and the transmission size under the same working conditions is high. Small; the required tension is small, and the pressure acting on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust, and pollution. However, the chain drive requires the position of the sprocket to be fixed to ensure that the chain is always in a tight state. If the position of the sprocket changes, an external tensioner is required to assist the transmission. The translation control of ...
