Abstract
A fixing apparatus for fixing a shaft to a mounting part and an actuator of a robot are provided. The fixing apparatus includes an inner ring and an outer ring. The inner ring has an outer tapered surface and is arranged to be sleeved on the shaft. The outer ring has an inner tapered surface that fits the outer tapered surface of the inner ring. The inner ring and the outer ring are both arranged to abut the mounting part in an axial direction of the shaft. The outer ring is configured to be detachably fixed to the mounting part, and the inner ring is squeezed by the outer ring to grip the shaft in a radial direction when the outer ring is fixed to the mounting part.
Claims20
A fixing apparatus for fixing a shaft to a mounting part, comprising:
- an inner ring having an outer tapered surface, the inner ring configured to be sleeved on the shaft;
- and
- an outer ring having an inner tapered surface, the inner tapered surface configured to fit the outer tapered surface of the inner ring,
- wherein the inner ring and the outer ring are both configured to abut the mounting part in an axial direction of the shaft,
- wherein the outer ring is configured to be detachably fixed to the mounting part, and
- wherein the inner ring is squeezed by the outer ring to grip the shaft in a radial direction when the outer ring is fixed to the mounting part.
A fixing apparatus for fixing a shaft to a mounting part, comprising:
- an inner ring having an outer tapered surface, the inner ring configured to be sleeved on the shaft;
- and
- an outer ring having an inner tapered surface, the inner tapered surface configured to fit the outer tapered surface of the inner ring,
- wherein the inner ring has an inner diameter originally smaller than an outer diameter of the shaft,
- wherein, when the outer ring is moved towards the mounting part and both the inner ring and the outer ring abut the mounting part in an axial direction of the shaft, the inner tapered surface of the outer ring squeezes the outer tapered surface of the inner ring to make the inner ring compress and grip the shaft, and
- wherein the outer ring is detachably fixed to the mounting part.
An actuator of a robot comprising a shaft, a mounting part and a fixing apparatus configured to fix the shaft to the mounting part, wherein the fixing apparatus comprises:
- an inner ring having an outer tapered surface, wherein the inner ring is sleeved on the shaft;
- and
- an outer ring having an inner tapered surface, wherein the inner tapered surface fits the outer tapered surface of the inner ring,
- wherein the inner ring and the outer ring both abut the mounting part in an axial direction of the shaft,
- wherein the outer ring is detachably fixed to the mounting part, and
- wherein the inner ring is squeezed by the outer ring to grip the shaft in a radial direction.
