Description
- Valid for: Hägglunds motors CA, CB, CBP and CBM
Features
- Easy mounting i.e. No alignment problems, couplings and bed plates are eliminated.
- Fast mounting of motor to driven shaft.
- Robust torque-transmitting.
- Controlled external forces on driven shaft.
- Space saving. i.e. close mounting to the driven machine.
- Take up radial and axial movements on driven shaft.
- Electrical isolated option to avoid current from passing through the hydraulic motor.
Product description
If the driven machine can stand the forces generated by the Hägglunds single ended torque arm arrangement, the Hägglunds single ended torque arm is an easy and favorable mounting solution for the Hägglunds hydraulic motor. The torque arm transmits the force generated by the hydraulic motor in to a fixed point. The length of the torque arm determine the force Fr (see chapter "Technical Data" - Table "External forces Fr, Fb for TCA") on motor and driven shaft.
The standard torque arm kit consists of the torque arm, screws, washers and an articulated connection.
The articulated connection is a flexible link which allows the motor to follow the rotation of customer shaft within specified limits of misalignment and eccentricity. See chapter "Mounting".
Note:
For installation instructions see Installation and maintenance manual for respective Hägglunds motor. (See chapter "Information" - Table "Required and additional documents")
