Abstract
The utility model discloses a planet frame, which comprises a chassis. A cylindrical shell is integrally casted on the upper surface of the chassis, cavities are arranged between the cylindrical shell and the chassis, a plurality of openings are arranged on the combined portion of the cylindrical shell and the chassis, and included angles formed by adjacent openings are the same. Installation holes are respectively arranged on the cylindrical shell between adjacent openings, and a through hole is arranged in the middle of the cylindrical shell. The through hole and the cavities arranged on the periphery of the through hole are areas for installing a solar wheel, and the plurality of openings and the cavities arranged on the inner side of the plurality of openings are areas for installing a planet wheel. The planet frame has the advantages of being compact in structure, light and rigid, easy to process and assemble and small in occupied area and having good practical value.
Description
Technical field
The utility model relates to a kind of planet carrier.
Background technique
Planet carrier is one of main member of planetary type gear transmission unit, and planet wheel shaft or bearing just are contained on the planet carrier.When planet wheel during as basic building block, it is to bear the maximum part of moment of face in the mechanism.To such an extent as to the structural design of planet wheel and bearing capacity, noise and the vibration etc. of making the load distribution transmission device between each planet wheel have very big influence.
The Rational structure of planet carrier should be in light weight, good rigidly, be convenient to processing and assembling.Its common structural type has dual-sided board integrated type, dual-sided board split and one-sided board-like three kinds.The all-in-one-piece good rigidly of dual-sided board; If this structure adopts solid forging then the cutting amount is very big; Therefore available casting and welding method obtain structure and the size blank near finished product; But should note eliminating casting or weld defects and internal stress, possibly produce distortion when not side will influence intensity, quality of processing and the use of planet carrier.
The model utility content
The purpose of the utility model provides a kind of planet carrier, is used to install the sun gear and the planet wheel of planetary reducer.
The technological scheme of the utility model is following:
A kind of planet carrier; Include the chassis, it is characterized in that: the upper surface on said chassis has the barrel-type casing of integrally casting moulding, and has cavity between barrel-type casing and the chassis; The connecting part on said barrel-type casing and chassis is provided with a plurality of openings respectively; Angle between the adjacent apertures is identical, on barrel-type casing between the adjacent apertures, is respectively equipped with mounting hole, and the middle part of barrel-type casing is provided with through hole; Said through hole and the cavity that is positioned at around the through hole are the sun gear mounting zone, described a plurality of openings and to be positioned at the inboard cavity of a plurality of openings be the planet wheel mounting zone.
Described planet carrier is characterized in that: the chassis around the barrel-type casing is provided with gear ring, and is meshed between the planet wheel of installing in the inner ring of gear ring and the planet wheel mounting zone.
The beneficial effect of the utility model:
The utility model compact structure has characteristics in light weight, good rigidly, and processing and assembling are all very simple and easy, and it is little to take up room, and has good use value.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of planet carrier includes chassis 1; The upper surface on chassis 1 has the barrel-type casing 2 of integrally casting moulding; And have cavity between barrel-type casing 2 and the chassis 1, barrel-type casing 2 is provided with three openings 3 respectively with the connecting part on chassis 1, and the angle between the adjacent apertures is identical; On barrel-type casing between the adjacent apertures 2, be respectively equipped with mounting hole 5, the middle part of barrel-type casing 2 is provided with through hole 3; Cavity around through hole 3 and the through hole 3 is that 7, three openings 3 in sun gear mounting zone and the cavitys that are positioned at three openings, 3 inboards are planet wheel mounting zone 6.
Claims (2)
1. planet carrier; Include the chassis, it is characterized in that: the upper surface on said chassis has the barrel-type casing of integrally casting moulding, and has cavity between barrel-type casing and the chassis; The connecting part on said barrel-type casing and chassis is provided with a plurality of openings respectively; Angle between the adjacent apertures is identical, on barrel-type casing between the adjacent apertures, is respectively equipped with mounting hole, and the middle part of barrel-type casing is provided with through hole; Said through hole and the cavity that is positioned at around the through hole are the sun gear mounting zone, described a plurality of openings and to be positioned at the inboard cavity of a plurality of openings be the planet wheel mounting zone.
