Abstract
The utility model discloses a planet carrier, and pertains to planet carriers for drive axle wheel edge planetary reduction gears. The planet carrier adopts a split type structure, and is formed by a mode that a planet carrier shell and a fixed plate are connected into a whole by a connecting bolt. The planet carrier shell has a semi-closed structure, wherein a plurality of bosses are arranged in an inner cavity of the shell; the top of each boss is opened and not closed by a panel; gaps for containing planet wheels are arranged between adjacent bosses; each boss is provided with a connecting hole; and each connecting hole comprises two sections, wherein one section close to the opening of the hole is an articulated unthreaded hole, and the other section adjacent to the articulated unthreaded hole is a threaded hole. The fixed plate is circular and provided with articulated connecting holes, wherein the number and the positions of the articulated connecting holes correspond to the number and the positions of the holes of the bosses on the planet carrier shell. The planet carrier has the advantages of being simple in structure, good in manufacturability, and convenient to assemble, disassemble and maintain, being capable of adopting standard bolts, and being low in total manufacturing cost.
Description
Technical field
The utility model relates to a kind of planetary wheel carrier, especially for a kind of planetary wheel carrier in the planetary reduction gear of ransaxle wheel limit.
Background technique
For the ransaxle of most belt wheels limit planetary reducer, planetary wheel carrier is to hold one of indispensable part of planet pinion.Present known planetary wheel carrier has integrated type and split type two types from structure.Integrated type planetary wheel carrier complex structure, manufacturability is bad, is difficult for casting and processing, the manufacture cost height; Split type planetary wheel carrier comprises planetary wheel carrier shell and planet wheel stand, and connects formation planetary wheel carrier in aggregates by bolt, and structure is simple relatively, but dismounting maintenance and inconvenient.
The model utility content
The purpose of this utility model is to provide a kind of: simple in structure, good manufacturability is easy to the dismounting maintenance, a kind of planetary wheel carrier of low cost of manufacture.
The technical solution of the utility model is as follows: this planetary wheel carrier adopts split-type structural, and it comprises planetary wheel carrier housing, connecting bolt, fixed plate, and it is in aggregates that planetary wheel carrier housing and fixed plate are connected by connecting bolt, the formation planetary wheel carrier.
Described planetary wheel carrier housing is a semi-closed structure, inner chamber has a plurality of boss, the top of each boss is opened wide, there is not the panel sealing, the neutral gear that holds planet wheel is arranged between boss and the boss, on each boss attachment hole is arranged, attachment hole comprises two sections, one section near the place, aperture is the articulation unthreaded hole, and another section that is right after the articulation unthreaded hole is a tapped hole.
Described fixed plate is a circular plate, and attachment hole is arranged on the fixed plate, and the hole is an articulation hole, and the quantity and the position of the boss hole on the quantity in hole and distributing position and the planetary wheel carrier housing are corresponding.
Described connecting bolt is the articulation hole bolt, the available standards part.
Beneficial effect: owing to adopted such scheme, the planetary wheel carrier housing is a semi-closed structure, inner chamber has boss, the top of each boss does not have the panel sealing, the quantity of boss is determined according to the number of planet wheel, neutral gear between boss and the boss is used for holding planet wheel, on each boss attachment hole is arranged, attachment hole comprises two sections, one section near the place, aperture is the articulation unthreaded hole, and another section that is right after the articulation unthreaded hole is a tapped hole, and the fixed plate that connection is used is a circular plate, employing steel plate cutting part or foundry goods can, attachment hole is arranged on the fixed plate, and the hole is an articulation hole, and the quantity in hole and distributing position are determined according to the quantity and the position of each boss hole on the planetary wheel carrier housing, planetary wheel carrier housing and fixed plate connect into an integral body by the articulation hole bolt, thereby constitute a planetary wheel carrier, simple in structure because of this planetary wheel carrier, be easy to casting and processing maintenance, low cost of manufacture has reached the purpose of this utility model.
Advantage: this planetary wheel carrier is simple in structure, and good manufacturability is convenient to the dismounting maintenance, and bolt can adopt standard piece, whole low cost of manufacture.
