Abstract
A torque transducer for mounting a motor includes a mounting flange, a motor flange, a body, and a strain gauge. The mounting flange is configured to secure the torque transducer to a fixed structure. The motor flange is configured to secure to a motor. The body interconnects the mounting and motor flanges. The body defines a channel about a longitudinal axis of the body and is configured to flex in response to the mounting flange and the motor flange rotating relative to one another in response to torque of the motor. The strain gauge is positioned on the body to measure flexation of the body.
Claims12
A torque transducer for mounting a motor, comprising:
- a mounting flange configured to secure the torque transducer to a fixed structure;
- a motor flange configured to secure to a motor;
- a body interconnecting the mounting and motor flanges, the body defining a channel about a longitudinal axis of the body, the body configured to flex in response to the mounting flange and the motor flange rotating relative to one another in response to torque of the motor;
- and
- a strain gauge positioned on the body to measure flexation of the body.
An instrument drive unit comprising:
- a mounting plate;
- a first motor having a drive shaft extending towards the mounting plate;
- and
- a first torque transducer securing the first motor to the mounting plate, the first torque transducer including:
- a motor flange secured to the first motor;
- a mounting flange secured to the mounting plate;
- a body interconnecting the mounting and motor flanges, the body defining a channel about a longitudinal axis of the body, the body configured to flex in response to the mounting flange and the motor flange rotating relative to one another in response to torque of the first motor, the drive shaft of the first motor extending into the channel;
- and
- a strain gauge positioned on the body to calculate torque applied by the first motor from flexation of the body.
