Abstract
The utility model relates to a planetary gear which comprises a gear body. The gear body is provided with a rim. Gear teeth are distributed on the outer round face of the rim of the gear body along a circumference direction. A left end inner hole and a right end inner hole are formed in the center portion of the rim of the gear body. A protruding baffle ring is arranged on the inner wall of the rim. The baffle ring is placed between the left end inner hole and the right end inner hole. A baffle ring hole is formed in the portion of the baffle ring. The left end inner hole, the baffle ring hole and the right end inner hole are communicated in sequence. The diameter of the left end inner hole and the right end inner hole is the same. The diameter of the baffle ring is smaller than that of the left end inner hole or the right end inner hole. The wall face of the left end inner hole and the wall face of the right end inner hole are formed by processing simultaneously. The novel planetary gear is convenient to process and manufacture and is accurate in accuracy control.
Description
Technical field
The utility model relates to the gear technique field, especially a kind of planetary pinion.
Background technique
Planetary pinion is widely used in various machineries.The main feature of Planetary Gear Transmission is that volume is little, and bearing capacity is large, stable working.But the Large-power High-Speed planetary gear transmission mechanism is complicated, requires accuracy of manufacturing high.Some type efficient is high in the Planetary Gear Transmission, but velocity ratio is little.Other types then velocity ratio can be very large, but efficient is lower.When making retarder with them, its efficient reduces with the increase of velocity ratio; Then might produce self-locking when making speed increaser.Existing planetary endoporus need to repeatedly machine, and precision control is difficult.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of planetary pinion is provided, its processing and fabricating is convenient, the precision precise control.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of planetary pinion, has the gear body, described gear body has wheel rim, the wheel rim periphery of described gear body has the circumferential gear teeth, the wheel rim center of described gear body has left end endoporus and right-hand member endoporus, the bossed baffle ring of described wheel rim inwall tool, described baffle ring is between left end endoporus and right-hand member endoporus, described baffle ring place has the baffle ring hole, described left end endoporus, the baffle ring hole, the right-hand member endoporus communicates along connecting, described left end endoporus is identical with the diameter of right-hand member endoporus, the diameter in described baffle ring hole is less than the diameter of left end endoporus or right-hand member endoporus, and the wall of the wall of described left end endoporus and right-hand member endoporus is processed to form simultaneously.
Further, the wall of the wall of described left end endoporus and right-hand member endoporus is processed to form simultaneously by the emery wheel with diameter,
The beneficial effects of the utility model are: the bossed baffle ring of planetary pinion wheel rim inwall tool of the present utility model, baffle ring is between left end endoporus and right-hand member endoporus, the left end endoporus is identical with the diameter of right-hand member endoporus, during processing and fabricating, the left end endoporus with place simultaneously the emery wheel of same diameter with the right-hand member endoporus, the emery wheel of the emery wheel of left end endoporus and right-hand member endoporus can be by the baffle ring interval, the wall of the wall of left end endoporus and right-hand member endoporus is processed to form simultaneously by the emery wheel with diameter, so so that the planetary pinion processing and fabricating is convenient, the precision precise control.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Wherein: 1. gear body, 2. left end endoporus, 3. right-hand member endoporus, 4. baffle ring.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of planetary pinion, has gear body 1, gear body 1 has wheel rim, the wheel rim periphery of gear body 1 has the circumferential gear teeth, the wheel rim center of gear body 1 has left end endoporus 2 and right-hand member endoporus 3, the bossed baffle ring 4 of wheel rim inwall tool, baffle ring 4 is between left end endoporus 2 and right-hand member endoporus 3, baffle ring 4 places have the baffle ring hole, left end endoporus 2, the baffle ring hole, right-hand member endoporus 3 communicates along connecting, and left end endoporus 2 is identical with the diameter of right-hand member endoporus 3, the diameter in baffle ring hole is less than the diameter of left end endoporus 2 or right-hand member endoporus 3, and the wall of the wall of left end endoporus 2 and right-hand member endoporus 3 is processed to form simultaneously by the emery wheel with diameter.
The bossed baffle ring 4 of planetary pinion wheel rim inwall tool of the present utility model, baffle ring 4 is between left end endoporus 2 and right-hand member endoporus 3, left end endoporus 2 is identical with the diameter of right-hand member endoporus 3, during processing and fabricating, left end endoporus 2 with place simultaneously the emery wheel of same diameter with right-hand member endoporus 3, the emery wheel of the emery wheel of left end endoporus 2 and right-hand member endoporus 3 can be by baffle ring 4 intervals, the wall of the wall of left end endoporus 2 and right-hand member endoporus 3 is processed to form simultaneously by the emery wheel with diameter, so so that the planetary pinion processing and fabricating is convenient, the precision precise control.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
