The invention relates to torque loading devices and provides a screw type torque loading device in order to solve the problem that torque loading of an existing closed parallelogram speed reducer transfer system is difficult. The screw type torque loading device comprises a first flange and a second flange. The first flange and the second flange are coaxially mounted. The screw type torque loadingdevice is characterized in that a concave cavity is formed in the end face of the big end of the first flange; a plurality of radial arms arranged around the center of the second flange at intervalsin the circumferential direction are arranged at the big end of the second flange; the radial arms are located in the concave cavity of the end face of the first flange; the sidewall of the concave cavity of the first flange is provided with a plurality of screw holes arranged at intervals in the circumferential direction; the screw holes communicate with the concave cavity of the first flange, and the axes of the screw holes are perpendicular to the axis of the first flange in a staggered mode; a torque loading bolt of which the tail end makes contact with the corresponding radial arm is arranged in each screw hole. The screw type torque loading device is simple in structure, safe and reliable, and facilitates adjustment of torque.
Description
technical field [0001] The present invention relates to a torque loader, more specifically, to a screw type torque loader. Background technique [0002] The reducer increases the torque at the output end by reducing the speed to achieve low-speed and heavy load at the output end of the reducer. For example, the rotary reducer of a certain type of excavator has a maximum torque of 745Nm at the input end and a maximum output torque of more than 18800Nm at the output end. In the design and manufacture process of the reducer, the durability of the reducer needs to be verified in order to verify the reliability and related performance of the reducer. In the common reducer operation system, two motors are generally used, one motor is used as the input, and the other motor is used as the load to realize the operation of the reducer under the maximum torque condition. The two required for such an operation system The total power of the motor needs to be large enough to meet the tes...
