Standard bearing pad servo driving guide wheel

Abstract

The invention discloses a standard bearing pad servo driving guide wheel. The standard bearing pad servo driving guide wheel comprises a servo motor (9) and a coaxial pad guide wheel part (13); the servo motor (9) is connected with a coupling; the coupling is connected with a speed reducer (11); the speed reducer (11) is connected with the coaxial pad guide wheel part (13) through a guide wheel connecting base (12); the coaxial pad guide wheel part (13) is connected with a guide wheel (7), and includes a guide wheel shaft (4); an alloy bearing A (5) and an alloy bearing B (6) are coaxially arranged at two ends of the guide wheel shaft (4); and the speed reducer (11) includes a worm rod (2) and a worm wheel (3). The standard bearing pad servo driving guide wheel is compact in structure, uses a standard bearing pad, unifies the shaft diameter of the guide wheel shaft, improves the rigidity of the shaft, improves the transmission precision, and prolongs the service life; and the servo motor and the speed reducer are directly connected to drive the guide wheel, so that the efficiency of the motor can be transmitted to the guide wheel shaft more effectively, and the transmission efficiency and the operation precision of the guide wheel shaft are improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a standard bearing bush servo-driven guide wheel. Background technique [0002] The existing dynamic pressure centerless grinding machine guide wheel dynamic pressure mechanism includes the original guide wheel part 1A, and the original guide wheel part 1A includes the guide wheel 6A, the guide wheel seat 9A, the driving motor 2A, the belt transmission part 3A, the gear transmission part 4A and the chain For wheel 5A, two specifications of middle alloy bearing 8A and rear alloy bearing 10A are used to support guide wheel main shaft 7A, see image 3 with Figure 4 . Although this structure can meet the requirements of most workpieces, it is still difficult to meet the requirements of some high-precision workpieces. The large and small bearing pads make it difficult to ensure coaxiality, difficult assembly, and high processing costs. Using V-belt and ordinary chain transmissi...

Problems solved by technology

Although this structure can meet the requirements of most workpieces, it is still difficult to meet the requirements of some high-precision workpieces. The large and small bearing bushes make it difficult to ensure coaxiality, difficult assembly, and high processing costs.

Using V-belt and ordinary chain transmission at the same time, the transmission accuracy is poor, the power loss of the motor is large, and the vibration is large during operation. When the sprocket is tensioned, an axial force will be generated on the shaft and the entire guide wheel seat, which will affect the overall accuracy of the guide wheel.
