Problems solved by technology
The backlash will affect the rotation accuracy, and the eccentricity of the gear will cause the accelerated wear of the gear and affect the life of the gear.
Existing gear devices for eliminating backlash: one is to add a set of servo motors, which has high manufacturing costs and complicated devices; the other is two coaxial gears, one of which is fixed and the other is floating on the fixed gear. The latter is connected by a spring, and the backlash is eliminated by the spring. Since the spring is installed on the gear, the size of the spring is limited, that is, the reverse torque is limited. If the reverse torque is too large, the device will fail, and both devices cannot eliminate the gear eccentric belt. to influence

The invention provides a device capable of eliminating a gear rotation clearance. The device comprises a driving wheel (1), a driven wheel A (2), a driven wheel B (3) and an X-shaped device, wherein the driving wheel (1) is fixed to the intersection point of the X-shaped device (4); the driven wheel A (2) and the driven wheel B (3) are fixed to the two tops, on the same side, of the X-shaped device (4) respectively; the driven wheel A (2) and the driven wheel B (3) separately mesh with a target gear. According to the device, no matter whether the driving wheel rotates clockwise or anticlockwise, the rotation precision of the gear can be ensured by one driven wheel; besides, when the target gear is eccentric, the positions of the driven wheels can be adjusted through the compression degreeof a spring, the gear rotation precision can be ensured, the gear cannot be stuck or excessively rubbed, and the service life of the gear is prolonged.
Description
technical field [0001] The invention relates to the technical field of gear matching, in particular to a device capable of eliminating the backlash of gear rotation. Background technique [0002] The gear requires a certain fit clearance in actual use, and there will be a certain machining error during production and processing. The accumulation of the fit clearance and the machining error will result in a certain rotation clearance. At the same time, due to the limitation of machining accuracy, there will often be a slight gap during gear machining. eccentric. The gyration clearance will affect the gyration accuracy, and the eccentricity of the gear will cause the accelerated wear of the gear and affect the life of the gear. Existing gear devices for eliminating backlash: one is to add a set of servo motors, which has high manufacturing costs and complicated devices; the other is two coaxial gears, one of which is fixed and the other is floating on the fixed gear. The lat...
