Unilateral speed reducer for mining conveying and transporting winch

Abstract

The invention discloses a unilateral speed reducer for a mining conveying and transporting winch. The unilateral 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 which are engaged with a big gear are arranged at the end parts of the input shaft; the big gear is arranged at the front end of the 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 on the sidewall of the bevel gear box; a pinion is fixedly arranged on a rotating shaft of the planetary frame; and a carrier gear rotationally arranged in the carrier gear box is engaged outside the pinion. The unilateral speed reducer for the mining conveying and transporting winch, disclosed by the invention, has the advantages of 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 mine transportation machinery, in particular to a single-side speed reducer for a mine transportation winch. Background technique [0002] Patent No. CN03132226.3 discloses a technical solution for handling and transporting winches. This solution adopts bevel gear and planetary gear transmission, which has high transmission efficiency, can realize soft start of large tonnage, and is suitable for the narrow working space in underground coal mines. , but the motor needs to be started 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...

[0002] Patent No. CN03132226.3 discloses a technical solution for handling and transporting winches. This solution adopts bevel gear and planetary gear transmission, which has high transmission efficiency, can realize soft start of large tonnage, and is suitable for the narrow working space in underground coal mines. , but it needs to start the motor frequently in forward and reverse directions when using it, 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. 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
