Description

Thin-wall spoke type large gear

Technical Field

The utility model relates to the technical field of thin-wall spoke type large gears, in particular to a thin-wall spoke type large gear.

Background

The gear, it is the toothed mechanical part that can be engaged with each other, it is extremely extensive in mechanical transmission and whole mechanical field, in order to save material and lighten the weight of the gear when making the gear with bigger diameter in the prior art, mostly design the gear into the spoke type, in order to save material cost at the same time, the gear wall thickness is thinner, but this kind of thinner gear makes the connection between gear and spindle not firm enough, because the contact area is smaller makes the frictional force reduce to some extent, the gear slips on the spindle very easily, therefore need a structure that can play a reinforcing role.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects that gears are easy to slip on a rotating shaft to generate deviation and the like in the prior art, and provides a thin-wall spoke type large gear.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the thin-wall spoke type large gear comprises an outer wheel, wherein an outer ring is arranged at the inner side end of the outer wheel, an inner ring is arranged at the inner side of the outer ring, a plurality of groups of connecting rods are connected between the outer ring and the inner ring, reinforcing rings are arranged on the end faces of the upper side and the lower side of the inner ring, a plurality of groups of reinforcing rods connected with the end face of the inner side of the outer wheel are arranged on the peripheral end face of each reinforcing ring, a plurality of groups of vertical plates are uniformly distributed on the end face of the outer side of each group of reinforcing rings around the center of each reinforcing ring in a circumferential mode, the vertical plates are trapezoidal, and the peripheries of the plurality of groups of vertical plates are in threaded connection with a rotating ring.

Preferably, the upper end face of the connecting rod is provided with an opening.

Preferably, the end face of the inner side of the vertical plate is provided with an anti-skid block.

Preferably, the peripheral end face of the swivel is provided with anti-skid grains.

The utility model provides a thin-wall spoke type large gear, which has the beneficial effects that:

through the trapezoidal vertical plates and the rotating ring, when the rotating ring is rotated, the multiple groups of vertical plates are gradually tightened inwards, the contact area is increased, and the gear is prevented from slipping on the rotating shaft;

through the reinforcing ring and the reinforcing rod, the toughness of the gear can be improved, the strength of the thin-wall gear is increased, and deformation is prevented.

FIG. 1 is a schematic structural view of a thin-walled radial bull gear according to the present invention;

fig. 2 is a schematic sectional structural view of a thin-walled spoke-type bull gear according to the present invention.

In the figure: 1. an outer wheel; 2. an inner ring; 201. an outer ring; 202. a connecting rod; 203. opening a hole; 3. a reinforcement ring; 301. a reinforcing bar; 4. a vertical plate; 401. anti-skid blocks; 5. rotating the ring; 501. and (4) anti-skid lines.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, a thin-wall spoke type large gear comprises an outer wheel 1, an outer ring 201 is arranged at the inner side end of the outer wheel 1, an inner ring 2 is arranged at the inner side of the outer ring 201, a plurality of groups of connecting rods 202 are connected between the outer ring 201 and the inner ring 2, reinforcing rings 3 are arranged on the end faces of the upper side and the lower side of the inner ring 2, a plurality of groups of reinforcing rods 301 connected with the end face of the inner side of the outer wheel 1 are arranged on the end face of the outer side of the reinforcing rings 3, a plurality of groups of vertical plates 4 are uniformly distributed on the outer side end face of the two groups of reinforcing rings 3 around the center of the reinforcing rings 3, the vertical plates 4 are trapezoidal, and the peripheries of the plurality of groups of vertical plates 4 are in threaded connection with a rotating ring 5.

The upper end face of the connecting rod 202 is provided with an opening 203, so that the weight of the connecting rod 202 is reduced, and the overall weight of the gear is reduced.

The anti-skidding blocks 401 are arranged on the end faces of the inner sides of the vertical plates 4, so that the anti-skidding effect between the vertical plates 4 and the external rotating shaft is better.

The peripheral end face of the rotating ring 5 is provided with anti-skid grains 501, so that the rotating ring 5 can be rotated conveniently.

A working mode; during operation, locate the periphery of outside pivot with this gear sleeve, rotate swivel 5 for multiunit riser 4 closely laminates with the pivot, increases area of contact, strengthens frictional force, has seted up trompil 203 on the up end of connecting rod 202, reduces the weight of connecting rod 202, makes the whole weight of gear reduce, and beaded finish 3 and stiffener 301 can promote the toughness of this gear, increase thin-walled gear's intensity, prevent to warp.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
