Symmetric speed reducer for mining conveying and transporting winch

Abstract

The invention discloses a symmetric speed reducer for a mining conveying and transporting winch. The symmetric speed reducer comprises a bevel gear box and a carrier gear box, wherein a lengthways input shaft is rotationally arranged at one side of the bevel gear box; shaft gears are arranged at the end parts of the input shaft; big gears are respectively engaged with two sides of the shaft gears; the big gears at two sides are respectively arranged at the front end of a transverse flat key shaft; a sun gear is arranged at the rear end of the flat key shaft; multiple planetary gears which are respectively rotationally arranged on a turntable of a planetary frame are engaged outside the sun gear; inner gear rings matching with the planetary gears are respectively fixedly arranged at two sides of the bevel gear box; a pinion is fixedly arranged on the rotating shaft of the planetary frame; and a carrier gear rotationally arranged in the carrier gear box is engaged outside the pinion. The symmetric speed reducer for the mining conveying and transporting winch, disclosed by the invention, has the advantages of a completely symmetric structure, high transmission efficiency, satisfaction with reliability of large-tonnage soft start systems and brake systems, simple production technology, operation convenience, and better safety as well as reliability; and rope rewinding and releasing operations and braking operation can be realized without starting up the electric motor by turning positively and negatively frequently when the symmetric conveying and transporting winch for mine is in use.

Description

technical field [0001] The invention relates to a new type of mining transport machinery, in particular to a new mining transport winch with planetary soft start. Background technique [0002] Patent No. 03132226.3 has been authorized by the Patent Office of the State Intellectual Property Office. This patent discloses a technical solution for handling and transporting winches. It is suitable for the narrow working space in the underground of coal mines, but it needs to start the motor frequently in forward and reverse directions during use, and there are problems such as high noise in use. For example, the brake belt is used to brake the outer ring of the inner gear to realize the transmission. One end of the brake belt is fixed to the base, and the other end is connected to the hand brake connecting rod. It is further amplified and acts on the outer ring of the inner gear, and a large radial force acts on the outer ring of the inner gear, resulting in severe vibration, lo...

For example, the brake belt is used to brake the outer ring of the inner gear to realize the transmission. One end of the brake belt is fixed to the base, and the other end is connected to the hand brake connecting rod. Further amplify and act on the outer ring of the inner gear, and a large radial force acts on the outer ring of the inner gear, resulting in severe vibration, loud noise, and serious friction and heat generation during the transmission process, bringing certain safety hazards
