Abstract
The utility model discloses a double-plate separate type planet carrier, which at least comprises a front planet plate and a rear planet plate, wherein the front planet plate and the rear planet plate are parallel with each other and are respectively independent, the central peripheries of the front planet plate and the rear planet plate are respectively provided with at least three corresponding axle holes which are through holes, the corresponding axles holes of the front planet plate and the rear planet plate are connected with bearings at the center of a planet wheel via pin shafts so as to fix the planet wheel between the front planet plate and the rear planet plate, the front planet plate is provided with a circular torque output axle hole, the thickness of the front planet plate is larger than that of the rear planet plate, the rear planet plate is provided with a central hole, and the diameter of the central hole is larger than the outer diameter of a sun wheel meshed with the planet wheel. The planet carrier can effectively reduce the unbalanced loading of the pin shaft, prolongs the service life of a gearbox, is processed easily and is repaired conveniently.
Description
Technical field
The utility model relates to a kind of planet carrier, particularly relates to a kind of pair of plate separating planet frame, belongs to small-sized planetary reduction gear apparatus field.
Background technique
Planet carrier is as the member in the Gear Planet Transmission, and its structural design is distributed the load between each planet wheel and the ability to bear of mechanism etc. has material impact.Common single armed planet carrier is a single plate structure, and the distortion of bearing pin stand under load is big, causes the planet wheel unbalance loading under the situation of discontinuity easily, bearing pin fracture, thereby the working life of reducing gear-box.And the cage planet carrier is a monolithic construction, generally adopts integral casting forming or welding fabrication, the processing cost height, and maintenance difficult, very impracticable to small-sized planetary speed reducer.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, and a kind of pair of plate separating planet frame is provided, and can effectively reduce the fracture of planet wheel bearing pin, improves the working life of gear-box, and its planet plate can distinguish processing separately, is convenient to maintenance.
The technological scheme that realizes the utility model purpose is: a kind of pair of plate separating planet frame, at least comprise move ahead starboard and back planet plate, the starboard that moves ahead is parallel with back planet plate and independent separately, before, the central periphery of back planet plate respectively is provided with at least three corresponding axis holes, described axis hole is a through hole, before, the axis hole of back planet plate correspondence and the bearing at planet wheel center by bearing pin be connected planet wheel is fixed on before, between the back planet plate, the starboard that moves ahead is provided with circular torque output shaft hole, move ahead the thickness of starboard greater than the thickness of back planet plate, back planet plate is provided with center hole, the diameter of described center hole greater than with the external diameter of the sun gear of planet wheel engagement.
The torque output shaft hole is positioned at the center of the side that the described starboard that moves ahead links to each other with planet wheel.
Described forward and backward planet plate is a flange type.
Described bearing pin is a straight pin.
Single arm type planet plate in use, machining error because of part, the distribution that a plurality of planet wheels are expert on the starboard can not be in full accord, cause the stressed inequality of planet wheel bearing pin, therefore when being subjected to bigger impulsive load, a certain bearing pin just might at first bending occur and fracture, and causes whole speed reducer operational failure.After adopting two plate planet carrier structures, when a certain planet wheel bearing pin at first is subjected to impact bending, because front and back planet plate and bearing pin adopt interference fit, the bearing pin that is hit so just is delivered to power on other bearing pins equably by back planet plate, make in the planet plate a certain bearing pin not reason bear separately than heavy load and rupture, also make deceleration function proper functioning.
Therefore, compared with prior art, the utility model has the advantages that:
Planet carrier of the present utility model is double plate structure independently separately, and planet wheel is fixed between the forward and backward planet plate, can effectively reduce the fracture of planet wheel bearing pin, improves the working life of gear-box, and its planet plate can distinguish processing separately, is convenient to maintenance.
Description of drawings
Fig. 1 is the schematic representation of two plate separating planet frames of the utility model and planet wheel assembling.
Wherein, 1, starboard moves ahead; 2, back planet plate; 3, axis hole; 4, planet wheel; 5, bearing pin; 6, torque output shaft hole; 7, center hole.
Embodiment
The utility model is described in further detail below by the drawings and specific embodiments.
As Fig. 1, of the present utility model pair of plate separating planet frame comprises: starboard 1 and back planet plate 2 move ahead, the starboard 1 that moves ahead is parallel and independent separately with back planet plate 2, the central periphery of forward and backward planet plate respectively is provided with three corresponding axis holes 3, described axis hole 3 is a through hole, and the axis hole 3 of forward and backward planet plate correspondence is connected by bearing pin 5 with the bearing at planet wheel 4 centers planet wheel 4 is fixed between the forward and backward planet plate; The starboard 1 that moves ahead is provided with circular torque output shaft hole 6, circular torque output shaft hole 6 is positioned at the center of the side that the starboard 1 that moves ahead links to each other with planet wheel 4, move ahead the thickness of starboard 1 greater than the thickness of back planet plate 2, back planet plate 2 is provided with center hole 7, its diameter greater than with the external diameter of the sun gear of planet wheel 4 engagement.
The forward and backward planet plate that adopts in the present embodiment is flange type, and used bearing pin 5 is a straight pin.
When planet carrier of the present utility model and planet wheel assembled, only need be positioned over planet wheel between the forward and backward planet plate, with straight pin forward and backward planet plate corresponding aperture were connected to get final product.And when the maintenance epicyclic transmission mechanism, only need straight pin is taken off from front or rear planet carrier, just can keep in repair planet wheel easily.
