How does the torque wrench multiplier work
Mar 04, 2020
Torque wrench multiplier is a combination of a circle or planetary gears in different combinations to drive the gears to rotate and output.In a planetary gear system,torque is input and output via the sun gear.Three or four planet gears are combined with the sun gear to drive rotation.
The circumferential gear in the torque wrench multiplier housing is engaged with the internal planetary gear,but the direction of rotation is opposite to that of the internal planetary gear.The reaction force arm prevents the housing from rotating integrally with the circumferential gear,and causes the planetary gear to rotate around the sun gear to drive the drive square head to rotate,thereby outputting torque.Without a reaction arm,torque cannot be output.
Let me tell you a few more points to note about the use of torque wrench multipliers:
(1)It is necessary to pay attention to the torque value of the torque wrench.Do not overload it.
(2)Maintain the coaxial alignment of the drive head of the torque wrench,the multiplier and the locked object as much as possible.
(3)Try to keep the plane of contact between the reaction force arm and the resisting object reliable.
(4)Try to keep the reaction force at a right angle to the reaction force arm.
(5)The reaction force point should be as far away from the multiplier as possible and within the safety triangle.
(6)For safety reasons,it is not allowed to use double arms or balanced reaction arms.
(7)To remove the multiplier,first remove the torque wrench and toggle the anti-rebound device,avoid knocking.
