Technical Field

The invention relates to a mechanical torque speed reducing mechanism, in particular to a mechanical torque speed reducing structure, and belongs to the technical field of mechanical transmission.

Background

The mechanical speed reducing mechanism is an important component of mechanical transmission, and in the technical field of speed reducing mechanisms, a torque-free transmission mechanism is generally used, so that the currently used mechanical speed reducing mechanism has the defect of damaging mechanical components after overload.

Disclosure of Invention

The invention aims to: the mechanical torque speed reducing structure overcomes the defect that the overload caused by no device torque damages mechanical parts of the existing mechanical transmission speed reducing mechanism.

The technical scheme adopted by the invention for solving the technical problems is as follows: a mechanical torque speed reducing structure is composed of a speed reducing gear box, a non-stage gear, a parallel bearing, a belleville spring, a double-position bearing, a torque friction disc, a positioning key, a transmission output shaft and an output shaft bearing, wherein the non-stage gear is arranged on the output shaft in the speed reducing gear box through the double-position bearing, and the torque friction disc is arranged on the transmission output shaft on one side of the non-stage gear through the positioning key; the two parallel bearings are arranged on the transmission output shaft, one parallel bearing is leaned against the left side of the torque friction disc, the other parallel bearing is leaned against the inner right side of the reduction gearbox body, the two parallel bearings are provided with the belleville springs, the torque friction disc and the non-stage gear are combined together through one parallel bearing of the belleville springs, and the belleville spring on the other parallel bearing is arranged on the reduction gearbox through the transmission output shaft of the output shaft bearing.

Has the advantages that: the invention adopts the gear meshed with the non-stage gear to transmit power to the non-stage gear, the non-stage gear transmits power to the torque friction disc through the friction force between the non-stage gear and the torque friction disc, and the torque friction disc and the output shaft are connected through the positioning key and cannot rotate freely, so that the transmission output shaft rotates under the transmission of the non-stage gear, and once the external load of the output shaft exceeds a certain limit, the torque friction disc and the non-stage gear start to slip, thereby achieving the purpose of overload protection and effectively overcoming the defect that the mechanical parts are damaged by overload caused by no torque of the existing mechanical speed reducing mechanism.
