Description

Novel drive gear limit structure

Technical Field

The utility model relates to a gear drive technical field, in particular to novel drive gear limit structure.

Background

Gears are toothed mechanical parts that can mesh with one another, and are used extremely widely in mechanical transmissions and in the entire mechanical field. When the gear is used as a reducer, the driving gears are meshed with each other to play a role in matching rotating speed and transmitting torque, but the driving gears are fixed in the shell of the reducer through the driving shaft, so that the positions of the driving gears are inconvenient to fix directly, and when a single gear is meshed with other gears, the meshed position is positioned on one side of the gear, when the single gear is meshed with other gears, the single side of the gear is stressed when the single gear is stressed to rotate, and the overall position of the gear can be deviated; patent CN112161026B discloses a top planet gear rim plate machinery limit structure, slides in the inside of activity hole through spacing bolt, and then can carry out limiting displacement and can adjust spacing bolt's position to the rim plate, changes the spacing to different positions rim plate, but owing to just solved the spacing problem that makes things convenient for the rim plate, nevertheless there is the meshing between gear and the other gears to take place the dislocation, the problem of breaking down easily.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a novel drive gear limit structure.

The utility model adopts the technical scheme as follows: the utility model provides a novel drive gear limit structure, the key lies in: including just to two spacing dishes that set up, spacing dish center is equipped with the main bearing hole, centers on the main bearing hole is equipped with a plurality of vice dead eye, be equipped with the round fixed orifices on the spacing dish, arbitrary wear to be equipped with the locking bolt in the fixed orifices in the spacing dish, arbitrary be equipped with a plurality of gear limiting plates on the spacing dish, the gear limiting plate with vice dead eye one-to-one sets up.

Preferably, the gear limiting plate is an arc-shaped plate, and the inner arc surface of the arc-shaped plate is in sliding contact with the outer peripheral surface of the gear.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1-2, a novel driving gear limiting structure comprises two limiting discs 1 which are just opposite to each other, a main bearing hole 2 is formed in the center of each limiting disc 1 and surrounds the main bearing hole 2 to be provided with a plurality of auxiliary bearing holes 3, a circle of fixing holes 4 are formed in each limiting disc 1, locking bolts 5 penetrate through the fixing holes 4 in each limiting disc 1, a plurality of gear limiting plates 6 are arranged on each limiting disc 1, and the gear limiting plates 6 and the auxiliary bearing holes 3 are arranged in a one-to-one correspondence mode. When the structure is used, two ends of a rotating shaft of the main gear a respectively penetrate through the main bearing holes, two ends of a rotating shaft of the pinion respectively penetrate through the pinion bearing holes, the pinion limiting plates limit the pinions b at fixed positions to prevent the gears from deviating, so that the pinions b and the main gear a can be stably meshed, and the pinions b and the main gear a are fixed between the two limiting plates through the locking bolts.

In this embodiment, the gear limiting plate 6 is an arc-shaped plate, and the inner arc surface of the arc-shaped plate is in sliding contact with the outer peripheral surface of the gear. In the more preferred scheme, arc fixed mounting is on spacing dish to the height of arc is greater than the thickness of pinion, and when the gear installation was between two spacing dishes, the arc and another spacing dish butt.

In this embodiment, the circumferential length of the arc plate is 1/2-2/3 of the circumference of the gear. In a more preferable scheme, the length of the peripheral surface of the arc-shaped plate is 2/3 of the perimeter of the gear, and by adopting the structure, the other parts of the pinion, except the part meshed with the main gear, are in sliding contact with the inner arc surface of the arc-shaped plate, so that the stability is improved.

In this embodiment, four fixing holes 4 are formed in each limiting disc 1, and the four fixing holes 4 are uniformly distributed near the edge of the limiting disc 1. By adopting the structure, the stress balance of the two limiting discs is improved.

In this embodiment, the locking bolt 5 passes through the fixing hole 4 on the other limiting disc 1 and is connected with a nut 7 through a thread. Compared with the direct threaded connection of a bolt and a limiting disc, the nut locking device has better connection stability.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar indications without departing from the spirit and scope of the present invention.
