Embodiment
[0028] Example: see Figure 1~Figure 11 , Including a motor 1, a planetary gear sleeve 4, a double planetary gear train, a base 5, one end cover 11, a cam 8 and two guide shafts 9, the cam 8 is located between the double planetary gear train, and the double planetary gear The tie and cam 8 are located between the base 5 and the end cover 11, and the two guide shafts 9 are in clearance fit with the base 5, the cam 8 and the end cover 11 respectively.
[0029] This embodiment generally includes a motor 1 and a planetary gear sleeve 4. The motor 1 and the planetary gear sleeve 4 are connected together by screws 3; there are four rotating wheels 7 and the rotating wheel 7 and the motor shaft 2 form two planets. Gear train, one of the planetary gear trains is located in the lower rotating gear cage 6, and the other planetary gear train is located in the upper rotating gear cage 10. There is a cam 8 between the two gear trains, and the two planetary gear trains, cam 8 and The double-r...

The invention belongs to the technical field of mechanical transmission and relates to a four-roller friction double-planet transmission device, in particular to a four-roller friction double-planet transmission device suitable for the transmission of miniature electric hydraulic tongs. The four-roller friction double-planet transmission device comprises a motor, a double-planet gear train mechanism, a planet wheel sleeve, a base, an end cover, a cam, two rotating cages and two guide shafts; the double-planet gear train mechanism is arranged in the planet wheel sleeve; the cam is arranged between the two planet gear trains; the double-planet gear train mechanism and the cam are arranged between the base and the end cover; and the guide shafts are respectively in clearance fit with the base, the cam and the end cover. The device disclosed by the invention is better than other transmission devices of the miniature electric hydraulic tongs and is reasonable and ingenious in structural design and convenient to mount and dismount; meanwhile, the device has the characteristics of small volume, low weight, high transmission efficiency and the like by adopting the transmission mode of double-roller friction.
Description
Technical field [0001] The invention relates to a four-roller friction double planetary transmission device, in particular to a four-roller friction double planetary transmission device suitable for the transmission of miniature electric hydraulic tongs. Background technique [0002] Planetary transmission devices, due to their small size and high transmission efficiency, occupy a large share in the transmission device market of micro-electric hydraulic tongs; however, a large part of the planetary transmission devices are complex in structure, which is not easy to manufacture and install, and is not easy to disassemble , And as the use time increases, problems such as noise and vibration will occur; it does not meet the requirements of modern industry for mechanical transmission devices. [0003] It can be seen that the design of the micro-electro-hydraulic pliers transmission device has obvious defects in the structure and use of the existing micro-electro-hydraulic pliers transm...
