Cycloidal gear differential device of winching machine

Abstract

The invention relates to a cycloidal gear differential device of a winching machine, belonging to the technical field of power transmission / transformation line construction equipment. The winching machine comprises a chassis, a winching disc and a reduction box, and a cycloidal gear reducing device comprises a camshaft, a shaft disc, a gear ring, a left end cover and a right end cover, wherein a left cam and a right cam are formed on the camshaft; the left cam is provided with a left planetary gear; the right cam is provided with a right planetary gear; the center of the shaft disc is provided with a camshaft bearing; the left and right planetary gears are sleeved on a group of planetary gear matching shafts; a group of gear ring positioning grooves is formed on the outer wall of the gear ring; the lower part of the left end cover is provided with an end cover support leg; the left end cover and the right end cover are connected; and a winching disc connecting shaft is supported on the left end cover and extends out of the left end cover to be connected with the winching disc. The invention is characterized in that the left end cover is composed of a first plate, a first pipe, a second plate, a second pipe and a third plate. The invention has the advantages that the strength of the left and right end covers is enhanced, the oil leakage phenomenon is avoided, the material is saved, the mounting process is fast, and the requirement for miniaturization of the winching machine can be met.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission and transformation line construction equipment, and in particular relates to a cycloid wheel differential device of a winch mill. Background technique [0002] The cycloid differential gear mentioned above is also called cycloid gear reducer or planetary gear reducer, which is used as traction, line tightening, pole, tower, and equipment such as transformer hoisting in the construction and maintenance of power transmission and transformation lines. On the winch mill of a special facility such as the winch mill, it is between the power source of the winch mill and the winch disc, and the speed of the power source (usually using a gasoline engine or similar power) is as high as thousands or even thousands of revolutions per minute. Change to low speed and pass to the capstan. [0003] The technical information about the winch can be seen in the published Chinese patent documents...

Problems solved by technology

[0005] Although the aforementioned CN2848809Y and CN201012886Y have corresponding technical effects, there are the following disadvantages: one, due to the left and right end caps (also known as left and right shaft ends) Cover) is a casting (cast aluminum alloy), so there are inevitably situations such as pores and sand holes, not only the overall strength is difficult to guarantee, but also oil seepage cannot be avoided, especially because the overall strength is difficult to meet the requirements, so at the left and right ends The cover is uniformly formed with end cover support legs (customarily called hanging legs in the industry), which are supported on the chassis by the end cover support legs, resulting in waste of raw materials and increased installation workload, because the end caps on the left and right end caps need to be removed during installation. The supporting legs of the cover are fixed to the chassis; secondly, in order to ensure the strength of the left and right end covers as much as possible, the overall shape of the left and right end covers is designed in the shape of a bamboo hat, resulting in an increase in volume, specifically, the cycloid The length of the wheel reduction device is unreasonably increased by about 3-5cm, which affects the miniaturization of the overall volume of the winch mill
