Description

Novel planet carrier

Technical Field

The utility model relates to a planetary reducer technical field, in particular to novel planet carrier.

Background

The planetary reducer is an industrial product with wide application, and can reduce the rotating speed of a motor and increase the output torque. The planetary reducer can be used as a matched component for industries such as hoisting, digging, transportation, building and the like. The planet carrier is one of the main components of the planetary gear transmission device, and the structures of the existing planet carrier are various, such as integral type, combined type, and integrated with an output shaft, etc., but the stability of the existing structure in the using process is not high enough, so the improvement is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a planet carrier that stability is high.

In order to achieve the above object, the present invention provides the following technical solutions:

a novel planet carrier comprises a disc; the upper side and the lower side of the disc are symmetrically provided with a transversely arranged mounting groove; the center of the disc is provided with a central hole; an input shaft connecting part is arranged at the center of the left side of the disc; an output shaft connecting part is arranged at the center of the right side of the disc; the input shaft connecting part, the output shaft connecting part and the disc are integrally formed; the outer side of the middle part of the mounting groove is provided with a first opening penetrating through the outer wall of the disc and a second opening communicated with the central hole.

To the further description of the present invention, a plurality of hollow grooves are uniformly distributed on the left side of the disc.

To further describe the present invention, the hollow grooves are four.

To the utility model discloses a further description, both sides are equipped with the arc lateral wall around the mounting groove.

The utility model has the advantages that:

the input shaft stretches into the disc centre bore from access shaft connecting portion, the sun gear sets up and passes through the input shaft transmission in centre bore position department, two planet wheels are installed respectively in the mounting groove, the planet wheel inboard is through first opening and sun gear meshing, the outside is through the internal tooth meshing of second opening and shell, thereby reach the speed reduction transmission effect, the output shaft then fixed connection is in output shaft connecting portion position department as power take off, sun gear and planet wheel have all been installed on the disk body in this design, and the transmission of sun gear and two planet wheels and shell internal tooth is on same straight line, overall structure's setting has reached the advantage that high stability and transmission precision are high.

Drawings

fig. 2 is a cross-sectional view a-a of fig. 1.

Detailed Description

The invention is further explained below with reference to the drawings:

as shown in fig. 1-2, a novel planet carrier comprises a disc 1; the upper side and the lower side of the disc 1 are symmetrically provided with a transversely arranged mounting groove 2; the center of the disc 1 is provided with a central hole 3; an input shaft connecting part 4 is arranged at the center of the left side of the disc 1; an output shaft connecting part 5 is arranged at the center of the right side of the disc 1; the input shaft connecting part 4 and the output shaft connecting part 5 are integrally formed with the disc 1; a first opening 6 penetrating through the outer wall of the disc 1 and a second opening 7 communicated with the central hole 3 are formed in the outer side of the middle part of the mounting groove 2; the planet wheels are rotatably connected in the mounting groove 2 through a rotating shaft, the sun wheel is arranged in the central hole 3, the input shaft penetrates through the input shaft connecting part 4 to drive the sun wheel to rotate, the sun wheel is meshed with the two planet wheels through the second opening 7, the two planet wheels are meshed with the inner teeth of the shell through the second opening 7, the two first openings 6 and the second opening 7 are in the same linear direction with the central hole 3, the two first openings and the second opening are kept in the same straight line during transmission, the transmission precision is better, and the stability is good when the sun wheel and the planet wheels are arranged in the disk body; the output shaft is fixedly connected with the output shaft connecting part 5 through threads or a key groove.

A plurality of hollow-out grooves 8 are uniformly distributed on the left side of the disc 1, the hollow-out grooves 8 are arranged to improve the rigidity of the structure, and the cost is reduced.

In the design, the number of the hollow-out grooves 8 is four.

Both sides are equipped with arc lateral wall 9 around mounting groove 2, and it is further firm as, the stability of very high structure to the planet wheel through arc lateral wall 9.

The above description is not intended to limit the technical scope of the present invention, and any modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are still within the scope of the technical solution of the present invention.
