Abstract
The utility model relates to a planetary gear set, which comprises a planetary fixing frame, at least three planetary gears (2) and at least three planetary shafts (3). The planetary gear set is characterized in that the planetary fixing frame is formed by an upper clamping plate (4) and a lower clamping plate (5), the upper clamping plate (4) and the lower clamping plate (5) are in parallel and separated arrangement, the planetary shafts (3) are uniformly arranged between the upper clamping plate (4) and the lower clamping plate (5), the planetary shafts (3) are in riveted fixation with the upper clamping plate (4) and the lower clamping plate (5), and the planetary gears (2) are respectively coated on the corresponding planetary shafts (3) via bearings (6). Axial displacement restriction of the upper clamping plate and the lower clamping plate is realized by the rivet connection of the planetary shafts, the upper clamping plate and the lower clamping plate, the upper clamping plate and the lower clamping plate employ welding fixation to realize the axial displacement restriction without being equipped with a connecting portion, thereby the planetary fixing frame is simple and reasonable in integral structure and convenient in processing.
Description
Technical field
The utility model relates to a kind of planetary gear set.
Background technique
Existing a kind of planetary gear set is shown in Fig. 5～7, include planet fixing frame 1 ', three planetary pinions 2 ', planet fixing frame 1 ' by punch holder 3 ' and die holder 4 ' form, three protruding down last joints 31 of punch holder 3 ' have ', die holder 4 have the following joint 4 of three epireliefs ', last joint 3 ' and following joint 4 ' be welded to each other is fixed together, punch holder 3 ' and die holder 4 ' between have uniformly at intervals three planet axis 5 ', three planet axis 5 ' be triangular shape to arrange, planet axis 5 ' top and the bottom have one and punch holder 3 respectively ' with the stepped part of die holder 4 ' axial limiting, described three planetary pinions 2 ' by three planet axis 5 of needle bearing 6 ' be set in respectively ' on, these three planetary pinions 2 ' independently of one another promptly are not meshing with each other.
There is following defective in above-mentioned planetary gear set:
1, planet fixed rack structure complexity, processing is inconvenient.Constitute and also will bend out three on the upper and lower clamping plate of planet fixing frame respectively and go up joints, joints down, but also will go up joint and following joint welded together.
2, because the existence of assembly error, unavoidably there is certain interval between three planetary pinions and punch holder and the die holder, and planetary gear set in use, because the existence of mismatch error, planetary pinion has the play of certain amplitude, in the course of time, because the collision friction of planetary pinion and upper and lower clamping plate, the gap is increasing between planetary pinion and punch holder and the die holder, so this planetary gear set is easily damaged, working life is short.
What 3, above-mentioned planetary gear set was used is needle bearing, and lubrication effect is poor, therefore also influences the working life of planetary gear set.
In sum, above-mentioned planetary gear set structure also can be further improved.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of simple and reasonable, processing planetary gear set easy to assembly is provided at above-mentioned prior art present situation, and this planetary gear set also has the advantage of long service life.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of planetary gear set, include planet fixing frame, at least three planetary pinions, at least three planet axis, it is characterized in that described planet fixing frame is made up of punch holder and die holder, punch holder and die holder parallel interval are provided with, described planet axis is uniform to be arranged between punch holder and the die holder, planet axis and punch holder and die holder riveted fixing, described planetary pinion then are set in respectively on each self-corresponding planet axis by bearing.
For preventing owing to the play in the planetary pinion margin of error, and it is impaired to cause rubbing between planetary pinion and the upper and lower clamping plate, pad is provided with pad between above-mentioned planetary pinion upper surface and the punch holder, and pad is provided with pad between described planetary pinion lower surface and the die holder.Pad plays certain buffer function, and can prevent planetary pinion directly with the clamping plate collision, effectively reduce rub between planetary pinion and the upper and lower clamping plate impaired.
For can be better with the planet axis axial limiting between last die holder, above-mentioned planet axis upper and lower has one and the stepped part of punch holder and die holder axial limiting respectively.
For guaranteeing lubricating between bearing and the planet axis, above-mentioned bearing is an oil-impregnated bearing.
Above-mentioned pad is the graphite nylon pad.The graphite nylon pad has better cushioning effect, and wear-resistant.
Above-mentioned planet axis and planetary pinion respectively have three, and it is uniform to be triangular shape, and these three planetary pinions do not mesh independently of one another mutually.The planetary gear set of this kind structure is generally based on three planetary pinions, and planet axis and planetary pinion also can be four certainly, and it is uniform to be quadrilateral, and these four planetary pinions do not mesh independently of one another mutually.
Compared with prior art, advantage of the present utility model is: the planet fixing frame that this patent application relates to is made up of punch holder and die holder, punch holder and die holder parallel interval are provided with, the axial limiting of last die holder is riveted by planet axis and punch holder and die holder and is realized, need not to be provided with joint on the upper and lower clamping plate and adopt welding fixedly to realize axial limiting, therefore the overall structure advantages of simple of planet fixing frame is easy to process.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Be depicted as a preferred embodiment of the present utility model as Fig. 1～4.
A kind of planetary gear set includes planet fixing frame 1, three planetary pinions 2, three planet axis 3.Described planet fixing frame 1 is made up of punch holder 4 and die holder 5, punch holder 4 and die holder 5 shapes triangular in shape, and have a perforation 41,51, punch holder 4 and die holder 5 parallel interval settings at punch holder 4 and die holder 5 center positions.Described planet axis 3 upper and lowers have one and the stepped part 31 of punch holder 4 and die holder 5 axial limitings respectively, described three planet axis 3 are that triangular shape is uniform to be arranged between punch holder 4 and the die holder 5, punch holder 4 and die holder 5 are provided with three mounting holes 42 that supply planet axis 3 to pass, 52, on the described planet axis 3, the lower end is passed mounting hole 42 respectively, 52 backs and punch holder 4 and die holder 5 riveted joints, form axial limiting, 31 of stepped part on the planet axis 3 and last, die holder 4,5 interior edge face contact, form axial limiting, 2 of described planetary pinions are set in respectively on each self-corresponding planet axis 3 and between punch holder 4 and die holder 5 by oil-impregnated bearing 6, and these three planetary pinions 2 do not mesh independently of one another mutually.Pad is provided with pad 7 between described planetary pinion 2 upper surfaces and the punch holder 4, and pad is provided with pad 8 between described planetary pinion 2 lower surfaces and the die holder 5.Described pad 8 is the graphite nylon pad.
