Problems solved by technology

However, if a single-torque motor or a double-torque motor is used to drive, the price is very high when a torque of more than 10kNm is required; the torque provided by the dual-gear drive is insufficient; due to the self-locking phenomenon of the double-worm gear drive, the risk of synchronous control is relatively high

Embodiment Construction

[0012] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0013] See attached figure 1 As shown, this kind of worm gear compound drive mechanism that provides high torque is characterized in that: the drive mechanism acts on the symmetrical two sides of the load 3, and a bearing with external teeth is installed at one end of the two sides. The outer ring of the bearing is fixedly connected with the load 3, and the gear reduction device 2 meshes with the external teeth of the bearing. The number of driving motor 1 group is 2, and a worm gear reducer 5 is installed at the other end, and the worm gear reducer 5 is driven by the drive motor 4 at the end of the worm gear, and an angular position sensor 6 is installed on the worm gear reducer 5 for Measure the angular position of the load, and both ends jointly drive the load 3;

[0014] The worm gear reducer 5 bears no less than 50% of...

Abstract

The invention is a worm gear compound drive mechanism that provides high torque. The mechanism adopts synchronous drive control of multiple servo motors, can provide low-speed high torque and has good economical double-end drive form, one end adopts position feedback, and the other end adopts torque Feedback control can be applied to the large-size frame of the aero-engine test turntable or the double-end drive of other equipment.

Description

technical field [0001] The invention relates to a worm gear compound driving mechanism providing high torque, which belongs to the field of mechanical drive transmission. Background technique [0002] The aero engine is the most widely used aero engine at present, and it is a highly complex and precise thermodynamic aero engine. The working conditions cannot be simulated and calculated to obtain accurate data from the design, so a large number of test and analysis must be relied on. Test technology is the technical support for the research and development of aero-engines. The related test work is divided into ground test, high-altitude simulation test and flight test. The ground test has the advantages of low test cost, high test time and personnel mobility, and high test operation safety. Test as many test equipment as possible and obtain the most detailed test data, so the ground test is the basis of other test work, providing technical reference and data support for subs...
