Abstract
A planetary gearing train structure relates to a mechanical transmission structure, and comprises a cylindrical pin, a right planet carrier body, a left planet carrier body, a planetary gear, a space ring, pin rollers, a planetary gear shaft, a check ring and a bolt, wherein the left planet carrier body is in a plate shape, the right planet carrier body is in a bowl shape, and the left planet carrier body and the right planet carrier body are connected through the bolt and the cylindrical pin to form a planet carrier, the planetary gear is sheathed on the planetary gear shaft and is arranged at the periphery of the planet carrier, the pin rollers are distributed between an inner hole of the planetary gear and the periphery of the planetary gear shaft, the space ring is arranged between the two rows of pin rollers, and the rotation-preventive check ring is arranged at the part of the planetary gear shaft extending out of the left and the right planet carrier bodies. The planet carrier of a split structure is adopted, so that the planetary gearing train structure has the advantages of compact structure, small volume, reliability in mounting, high strength, long service life, and convenience in installation and maintenance.
Description
Technical field
The utility model relates to a kind of train of gearings of mechanical transmission fields, particularly a kind of epicyclic train.
Background technique
Different with the fixed axis gear that rotatingshaft is fixing, planetary pinion is the unfixed gear of a kind of rotation axis, and it is mounted in a rotary support---on the planet carrier.Planetary pinion is except can be as fixed axis gear rotating round oneself rotatingshaft, and their rotatingshaft is also along with planet carrier, around the rotational of other gear.Rotation around own axis is called " rotation ", is called " revolution " around the rotation of other Gear axis, and the planet just as in the solar system hence obtains one's name.
Planetary pinion is widely used in mechanical field, can realize multiple use: the deceleration of the separation of motion and synthetic, big speed ratio and high-power transmission etc.
But the drive mechanism of present existing epicyclic train is complicated, mostly is integral type, and the dismounting inconvenience is unfavorable for maintenance and replacing.
The model utility content
The purpose of this utility model is invented the planetary pinion architecture of a kind of compact structure, split-type structural planet carrier that volume is little.
The utility model is made of straight pin, right lateral star support body, left lateral star support body, planet wheel, spacer ring, roller, planet wheel shaft, back-up ring, bolt, left lateral star support body is tabular, right lateral star support body is bowl-shape, link together by bolt and straight pin and to constitute the planet support body, planet wheel is enclosed within on the planet wheel shaft, is arranged on the planet support body circumference, be covered with roller between the endoporus of planet wheel and planet wheel shaft cylindrical, be provided with the anti-rotation spacer ring between two row's rollers, on the part of stretching out left and right sides planet support body of planet wheel shaft, back-up ring is set.
Preferred version: the pin-and-hole of left lateral star support body is a counterbore, in case in the using process, straight pin breaks away from from pin-and-hole, thereby makes failure mechanisms.
Further preferred version: left lateral star support body is provided with the screw thread top wire hole, and in maintenance process, the screw of screwing on can make left and right sides planet support body split like a cork.
Planetary pinion architecture of the present utility model adopts the split-type structural planet carrier, compact structure, and volume is little; Safe and reliable, the intensity height, the life-span is long; Also have the screw thread top wire hole, installation and maintenance are easy.

Left lateral star support body 3 is tabular, and right lateral star support body 2 is bowl-shape.As Fig. 2, have three screw thread top wire holes 10 on the left lateral star support body 3, in maintenance process, the screw of screwing on can make left and right sides planet support body split like a cork.
As Fig. 3, the pin-and-hole of left lateral star support body 3 is a counterbore, in case in the using process, straight pin breaks away from from pin-and-hole, thereby makes failure mechanisms.
The structure embodiment of anti-rotation spacer ring 5 is a rectangle back-up ring as shown in Figure 5, and two minor faces have outside radian.
