Abstract

The invention relates to a four-roller friction double-planetary-gear transmission device, in particular to a four-roller friction double-planetary-gear transmission device suitable for miniature electric hydraulic tong transmission and belongs to the technical field of mechanical transmission. The four-roller friction double-planetary-gear transmission device comprises a motor, a double-planetary-gear system mechanism, a planetary gear sleeve, a base, an end cover, a cam, two rotary cage sleeves and two guide shafts. The double-planetary-gear system mechanism is arranged in the planetary gearsleeve. The cam is located in the double-planetary-gear system mechanism. The double-planetary-gear system mechanism and the cam are located between the base and the end cover. The guide shafts are in clearance fit with the base, the cam and the end cover correspondingly. The double-planetary-gear transmission device is superior to other miniature electric hydraulic tong transmission devices, isreasonable and ingenious in structure design and convenient to mount and demount and has the characteristics of being small in size, light in weight, high in transmission efficiency and the like through a four-roller friction transmission method.

Description

technical field [0001] The invention relates to a planetary gear transmission, in particular to a planetary gear transmission suitable for the transmission of micro-electrohydraulic pliers. Background technique [0002] Planetary transmission, due to its small size and high transmission efficiency, occupies a large share in the transmission market of micro-electrohydraulic tongs; but a large part of the planetary transmission has a complex structure, which is not easy to manufacture and install, and is not easy to disassemble. , and with the increase of use time, problems such as noise and vibration will appear; it does not meet the requirements of modern industry for mechanical transmission devices. [0003] It can be seen that the design of the micro-electric hydraulic pliers transmission device and the existing micro-electric hydraulic pliers transmission device have obvious defects in structure and use. The transmission device of hydraulic pliers - planetary gear transm...
