Abstract
A gear device includes a gear attached to a shaft to rotate integrally with the shaft, a pair of bearings located across the gear in a direction in which the shaft extends and supporting the shaft in a rotatable manner, and a plurality of removable members attached to the gear. The plurality of removable members are attached to two surfaces of the gear intersecting with the shaft. Each removable member of the plurality of removable members faces a bearing of the pair of bearings located across the gear.
Claims18
A gear device, comprising:
- a gear attached to a shaft to rotate integrally with the shaft;
- a pair of bearings located across the gear in a direction in which the shaft extends, the pair of bearings supporting the shaft in a rotatable manner;
- and
- a plurality of removable members fixed to two surfaces of the gear intersecting with the shaft, each removable member of the plurality of removable members facing a different bearing of the pair of bearings located across the gear.
A gear device, comprising:
- a gear attached to a shaft to rotate integrally with the shaft;
- a pair of bearings located across the gear in a direction in which the shaft extends, the pair of bearings supporting the shaft in a rotatable manner;
- and
- a plurality of removable members attached to two surfaces of the gear intersecting with the shaft, each removable member of the plurality of removable members facing a bearing of the pair of bearings located across the gear, wherein
- the plurality of removable members are attached to the two surfaces of the gear intersecting with the shaft, and include two rings, at least a portion of each ring of the two rings facing the pair of bearings.
A bearing removal method for removing a pair of bearings from a gear device, the gear device including a gear attached to a shaft to rotate integrally with the shaft, the pair of bearings located across the gear in a direction in which the shaft extends and supporting the shaft in a rotatable manner, and a plurality of removable members fixed to two surfaces of the gear intersecting with the shaft, each removable member of the plurality of removable members facing a different bearing of the pair of bearings, the method comprising:
- urging the plurality of removable members away from the gear to move the plurality of removable members away from the gear while each removable member of the plurality of removable members is in contact with a bearing of the pair of bearings facing the removable member of the plurality of removable members.
