Description

A gear with adjustable tooth angle

technical field

The utility model relates to the field of gears, in particular to a gear with an adjustable tooth angle.

Background technique

A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. Due to the good reliability of gear transmission, strong bearing capacity, stable transmission ratio, low noise, ability to withstand heavy loads, and long service life, transmission gears are widely used in machinery, instrument and other manufacturing industries. Some of the teeth of existing gears can be disassembled, and these teeth are either straight teeth or helical teeth. The advantages of straight teeth and helical gears cannot be displayed at the same time.

In view of the above shortcomings, it is necessary to design and develop a gear with an adjustable tooth angle, which can make up for the above shortcomings.

Utility model content

In order to solve the above existing problems, the utility model provides a gear with an adjustable tooth angle.

The utility model is realized through the following technical solutions: a gear with an adjustable tooth angle, including a base wheel and a tooth block, a number of blind holes are uniformly arranged on the arc-shaped end surface of the base wheel, and the base wheel There are several threaded hole groups distributed in a circle on one side, and each threaded hole group corresponds to the blind holes on the base wheel one by one. The blind hole of the gear tooth block is formed by vertically fixing the insertion rod at the bottom of the gear tooth. The holes are arranged on the insertion rod in a rotating manner from bottom to top, the distance between two adjacent through holes on the insertion rod is the same as the distance between the two adjacent threaded holes on the threaded hole group, the through holes on the insertion rod The number of holes is the same as the number of threaded holes on each threaded hole group, the axis of the through hole is perpendicular to the axis of the insertion rod, the insertion rod on the tooth block is inserted into the blind hole, and the insertion rod is connected to the base The threaded holes on the wheel are secured by bolts.

Preferably, the included angle between the axis lines of two adjacent through holes of the insertion rod is 5°.

Preferably, the bolts are countersunk head bolts.

Preferably, a degree mark is engraved next to the threaded holes in the threaded hole group.

Compared with the existing technology, the beneficial effect of the utility model is: the utility model adjusts the tooth block of the rotating wheel, so that the teeth of the gear can be changed from straight teeth to helical teeth, and the gear teeth can be adjusted according to different working conditions The different inclinations make the gear more versatile and better able to adapt to the environment, and the gear is convenient to replace damaged gear teeth and has stronger practicability.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figures 1, 2, 3, and 4, a gear with an adjustable tooth angle includes a base wheel 1 and a tooth block 4, and several blind holes are evenly provided on the arc-shaped end surface of the base wheel 1. 1-1, the side of the base wheel 1 is circularly distributed with several threaded hole groups, each threaded hole group corresponds to the blind hole 1-1 on the base wheel 1 one by one, and several threaded hole groups are arranged in a row The threaded hole 2 is formed, and the threaded hole 2 vertically runs through the corresponding blind hole 1-1. The tooth block 4 is formed by vertically fixing the insertion rod 4-2 at the bottom of the tooth 4-1. The tooth 4 -1 The bottom is flat, the insertion rod 4-2 is evenly provided with several through holes 4-3 arranged from bottom to top, and several through holes 4-3 are arranged on the insertion rod 4-3 in a rotating manner from bottom to top 2, the distance between the two adjacent through holes 4-3 on the insertion rod 4-2 is the same as the distance between the two adjacent threaded holes 2 on the threaded hole group, the through holes on the insertion rod 4-2 The number of holes 4-3 is the same as the number of threaded holes 2 on each threaded hole group, the axis of the through hole 4-3 is perpendicular to the axis of the insertion rod 4-2, and the insertion rod on the gear tooth block 4 4-2 is inserted into the blind hole 1-1, and the insertion rod 4-2 and the threaded hole 2 on the base wheel 1 are fixed by bolts 3.

The included angle between the axis lines of two adjacent through holes 4-3 of the insertion rod 4-2 is 5°.

The bolt 3 is a countersunk head bolt.

A degree mark 5 is engraved beside the threaded holes in the threaded hole group.

working principle:

When the working condition requires a spur gear, by turning the insertion rod 4-2 that has been inserted into the blind hole 1-1 on the base wheel 1, screw the bolt 3 from the corresponding threaded hole 2 marked "0°" and insert it In the through hole 4-3 at the uppermost end of the rod 4-2, and tighten the bolt 3, so that the gear is a spur gear. When the working condition requires a helical gear, loosen and take out the bolt 3, and then turn and adjust the insertion rod 4-2. Make the threaded hole 2 marked with different degrees face the through hole 4-3 on the corresponding insertion rod 4-2, and screw in the bolt 3. Whenever a degree is adjusted, other gear teeth are also the same degree, according to Working conditions can be adjusted to different degrees.
