Abstract
A planet carrier comprises a planet frame and a planet carrier cover, wherein one end face of the planet carrier cover is provided with a spindle. The planet carrier is characterized in that the other end face of the planet carrier cover is provided with a connection part which is connected with the planet frame through a bolt. The planet carrier has the advantages of lowering producing cost of the planet carrier and benefiting assembling of the planet carrier and a sun wheel and a planet wheel arranged in the planet carrier.
Description
Technical field
The utility model belongs to a kind of planetary gears, relates to a kind of planetary planet carrier.
Background technique
As shown in Figure 1, the planetary planet carrier of tradition is provided with planetary frame and planet carrier lid, and between planetary frame and planet carrier lid, connecting body is installed, connecting body and planetary frame are integrally formed, is connected by bolt between connecting body and the planet carrier lid, again at the middle part of connecting body and planetary frame installation sun gear and planet wheel.
The outer wall of planetary frame also has the gear teeth, and this material to planetary frame is had relatively high expectations, because connecting body and planetary frame are integrally formed, therefore, connecting body also needs the material the same with planetary frame.
Its shortcoming is that because connecting body and planetary frame are integrally formed, connecting body is the same with the material of planetary frame, has increased the fabricating cost of planet carrier.
The model utility content
The purpose of this utility model provides a kind of planet carrier that can reduce manufacture cost.
For achieving the above object, a kind of planet carrier described in the utility model comprises planetary frame and planet carrier lid, and an end face of described planet carrier lid is provided with rotating shaft, its key is: the other end of described planet carrier lid is provided with connecting body, and this connecting body is connected through bolt with described planetary frame.
Described planet carrier lid is integrally formed with described connecting body.And planet carrier lid to material require relatively lowly, connecting body has just adopted and the same material of planet carrier lid, has just reduced the cost of planet carrier on the whole.
Described planet carrier lid and described connecting body have the bolt via hole, and described planetary frame has bolt hole, after described bolt passes the bolt via hole, stretches in the described bolt hole.
Bolt connecting mode, the installation of be more convenient for planet carrier and inner sun wheel thereof and planet wheel.
Remarkable result of the present utility model is: a kind of planet carrier that can reduce manufacture cost is provided, also has been convenient to the assembling of planet carrier and inner sun wheel thereof and planet wheel, reduced the difficulty of planetary frame manufacturing process.
Description of drawings
Fig. 1 is the assembling assumption diagram of existing planet carrier;
Fig. 2 is an assembling assumption diagram of the present utility model;
Fig. 3 is the structural drawing of the utility model planet carrier lid.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Shown in Fig. 2,3, a kind of planet carrier comprises planetary frame 1 and planet carrier lid 2, and an end face of described planet carrier lid 2 is provided with rotating shaft, its key is: the other end of described planet carrier lid 2 is provided with connecting body 2a, and this connecting body 2a is connected through bolt 3 with described planetary frame 1.
Described planet carrier lid 2 is integrally formed with described connecting body 2a.And requiring of 2 pairs of materials of planet carrier lid is relatively low, and connecting body 2a has just adopted with planet carrier and covered 2 the same materials, has just reduced the cost of planet carrier on the whole.
Described planet carrier lid 2 and described connecting body 2a have bolt via hole a, and described planetary frame 1 has bolt hole b, after described bolt 3 passes bolt via hole a, stretches among the described bolt hole b.
Bolt connecting mode, the installation of be more convenient for planet carrier and inner sun wheel thereof and planet wheel.
Although above structure is described preferred embodiment of the present utility model in conjunction with the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, above-mentioned embodiment only is schematic rather than determinate, those of ordinary skill in the art is under enlightenment of the present utility model, under the prerequisite of the utility model aim and claim, can make multiple similar expression,, change the material of planet carrier lid 2 etc. as the quantity of change bolt 3.Such conversion all falls within the protection domain of the present utility model.Such conversion all falls within the protection domain of the present utility model.
