Abstract
The utility model discloses a planet gear. The planet gear comprises a gear body and is characterized in that the gear body is provided with a rim, a gear is arranged on the outer circular surface of the rim of the gear body, and a pressure angle of the gear is 25-27 degrees; a left end inner hole and a right end inner hole are formed in the center of the rim of the gear body, and a baffle ring is arranged between the left end inner hole and the right end inner hole. The planet gear has the advantages that the baffle ring is arranged between the left end inner hole and the right end inner hole, and the diameter of the left end inner hole is the same as that of the right end inner hole, so that the left end inner hole and the right end inner hole are easy to process and manufacture, and control accuracy is high; besides, the pressure angle of the planet gear is 26.5 degrees, so that the pressure angle of the planet gear is reasonable, mechanical strength is high, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of planetary pinion.
Background technique
Planetary pinion is widely used in various machinery.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 more complicated, require accuracy of manufacturing high.In Planetary Gear Transmission, some type efficiency is high, but velocity ratio is little.Other types velocity ratio can be very large, but efficiency is lower.While with them, making retarder, its efficiency reduces with the increase of velocity ratio, likely produces self-locking while making speed increaser.Simultaneously, existing planetary endoporus need to repeatedly machine, and it is more difficult that precision is controlled.
In addition, current planetary pressure angle adopts 20 °, although transmission efficiency is better, the shortcoming existed is that in use planetary pinion easily forms Undercutting Phenomenon, planetary bending resistance and impact resistance a little less than, working life is shorter.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, provides a kind of processing and fabricating convenient, precision precise control, and the high planetary pinion of tooth section mechanical strength.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of planetary pinion, comprise the gear body, it is characterized in that: described gear body has wheel rim, on described gear body wheel rim periphery, is provided with gear, and the pressure angle of gear is 25-27 °; The wheel rim center of described gear body has left end endoporus and right-hand member endoporus, between left end endoporus and right-hand member endoporus, is provided with baffle ring.
Described left end endoporus is identical with the diameter of right-hand member endoporus.
Be provided with equally distributed baffle ring hole on described baffle ring.
The diameter in described baffle ring hole is less than the diameter of left end endoporus and right-hand member endoporus.
Described baffle ring is by stainless steel material is made, thickness is 1-2cm baffle ring.
Described gear body by stainless steel material make, gear body in the form of a ring, the thickness of gear body is 2-4cm.
The thickness of described gear body is 3cm, and the thickness of baffle ring is 1.8cm.
The pressure angle of described gear is 26.5 °.
Owing to having adopted technique scheme, compared with prior art, the utility model arranges baffle ring between planetary 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 the emery wheel of same diameter with the right-hand member endoporus simultaneously, 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 by the emery wheel of same diameter simultaneously, therefore make the planetary pinion processing and fabricating convenient, the precision precise control.In addition, pressure angle of the present utility model is 26.5 °, makes planetary pressure angle more reasonable, and its mechanical strength is good, obtained prolongation working life.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
The accompanying drawing explanation
The cross section structure schematic diagram that Fig. 1 is a kind of embodiment of the utility model;
In figure: 1-gear body; 2-baffle ring hole; 3-right-hand member endoporus; 4-left end endoporus; The 5-baffle ring.
Embodiment
Embodiment:
As described in Figure 1, a kind of planetary pinion, comprise gear body 1, and described gear body 1 has wheel rim, on described gear body wheel rim periphery, is provided with gear, and the pressure angle of gear is 25-27 °.The wheel rim center of described gear body 1 has left end endoporus 4 and right-hand member endoporus 3, between left end endoporus 4 and right-hand member endoporus 3, is provided with baffle ring 5.
In the present embodiment, described left end endoporus 4 is identical with the diameter of right-hand member endoporus 3.Be provided with equally distributed baffle ring hole 2 on baffle ring 5, simultaneously, the diameter in described baffle ring hole 2 is less than the diameter of left end endoporus 4 and right-hand member endoporus 3.
