Detecting device for adjustable transmission clearance and transmission clearance adjustment mechanism

Abstract

The invention discloses a detecting device capable of adjusting a transmission gap and a transmission gap adjusting mechanism. The detecting device capable of adjusting the transmission gap comprises the transmission gap adjusting mechanism and a displacement detection mechanism. The transmission gap adjusting mechanism comprises a first support, a rotating assembly, a second support and an elastic assembly, wherein the first support is provided with a first plate and a second plate perpendicular to the first plate, the first plate is fixed to a rack, the second plate is provided with at least two threaded holes, the rotating assembly comprises a rotating shaft, the side edge of the first plate of the first support is fixed to the rotating assembly, the second support is fixed to the rotating assembly and is parallel to the second plate of the first support, and the elastic assembly is arranged in containing space. According to the detection device capable of adjusting the transmission gap, by keeping meshing of a gear and a rack, accumulated errors of reading of a jumping gear and an encoder due to long-term meshing abrasion can be effectively avoided, the maintenance labor is reduced, and the equipment cost is reduced.

Description

technical field [0001] The invention relates to a stroke detection device for rack and pinion transmission, in particular to a detection device for adjustable transmission clearance. The invention also relates to a transmission gap adjustment mechanism. Background technique [0002] Rack and pinion transmission is one of the most widely used transmission methods. It has large transmission power, high efficiency, stable operation, and can ensure a constant transmission ratio. It is suitable for fast and accurate positioning mechanisms. With the improvement of the degree of automation of mechanical equipment, the application of detection technology in equipment is becoming more and more extensive, and the position of these equipment needs to be monitored in real time during normal operation. At present, encoder control technology is generally used in China for continuous detection of position signals, which can greatly improve the degree of automation and reliability, realize...

Problems solved by technology

Therefore, the detection device in the prior art has the following disadvantages: the side clearance of the fixed mesh transmission cannot be adjusted, and after long-term mesh wear, the normal line of the rack is no longer tangent to the pitch circle of the gear, resulting in accumulated errors during the transmission process , affecting the accurate counting of the encoder, causing the value of the encoder to jump, causing a long downtime, increasing the maintenance man-hours, and increasing the equipment cost
