Abstract
A seal structure for a torque sensor fixed between a first member and a fixed portion of a reducer having a fixed portion and a movable portion rotatably supported with respect to the fixed portion around a predetermined axis line, wherein the torque sensor detects a torque around an axis line and has an annular shape seal member surrounding an outer periphery of the torque sensor, and the seal member is compressed by the fixed portion and the first member in a direction along the axis line.
Claims6
A seal structure for a torque sensor, the seal structure being fixed to a position between a first member and a fixed portion of a reducer, which includes the fixed portion and a movable portion rotatably supported by the fixed portion around a predetermined axis line,
- wherein the torque sensor detects a torque around the axis line,
- wherein the seal structure comprises an annular shape seal member surrounding an outer periphery of the torque sensor, and
- the seal member is compressed by the fixed portion and the first member in a direction along the axis line.
A seal structure for a torque sensor, the seal structure being fixed to a position between a first member and a fixed portion of a reducer, which includes the fixed portion and a movable portion rotatably supported by the fixed portion around a predetermined axis line,
- wherein the torque sensor is fixed to the first member using an adapter and detects a torque around the axis line,
- wherein the seal structure comprises an annular shape seal member surrounding an outer periphery of the torque sensor, and
- the seal member is compressed by the fixed portion and the adapter in a direction along the axis line.
A robot comprising:
- a first member;
- a second member;
- a reducer that supports the second member so as to be rotatable around a predetermine axis line with respect to the first member;
- a torque sensor fixed to a position between the reducer and the first member, the torque sensor detecting a torque around the axis line;
- and
- an annular shape seal member surrounding an outer periphery of the torque sensor, wherein
- the reducer includes a fixed portion to which the torque sensor is fixed and a movable portion which is rotatably supported by the fixed portion around the axis line, and
- the seal member is compressed by the fixed portion and the first member in the direction along the axis line.
