Problems solved by technology

[0002] At present, the large gear installed on the outer circle of the cement mixer drum is an integral structure, and it is also an important part of the cement mixer. However, due to the harsh working environment of the cement mixer, the degree of wear of the large gear is average. Larger, so the service life of the large gear is relatively low. Once the large gear wears to a certain extent, it must be replaced, so the use cost of the cement mixer is relatively high. At the same time, because the existing large gear is an integral In the structural form, if one of the teeth is damaged, the entire large gear will have to be scrapped, which further increases the cost of use. In addition, due to the large diameter and parameters of the gear, it is not allowed to use special equipment, which will not only make the manufacturing The process is complicated, and at the same time, it will also make the manufacturing cost higher

Embodiment Construction

[0011] In the figure, the structure of the large gear of the cement mixer includes: ring gear 1, gear teeth 2, pin shaft 3, annular groove 4, boss 5, the gear teeth 2 of the large gear are independent from the ring gear 1, and the gear The bottom of the tooth 2 is formed with a boss 5, and an annular groove 4 is formed on the outer circle of the ring gear 1. The teeth 2 are evenly embedded in the annular groove 4 of the ring gear 1. The holes on the bottom surface of the annular groove 4 are fixed, and the pin shaft 3 is fixed between the gear teeth 2 and the ring gear 1 .

Abstract

The invention discloses a large gear structure of a cement mixer. According to the large gear structure of the cement mixer, the teeth and the gear ring of a large gear are separately independent, the bottom of every gear tooth is provided with a boss, the outer circumference of the gear ring is provided with a ring groove, the gear teeth are evenly distributed and embedded into the ring groove of the gear ring, the bottom boss of every gear tooth is fixed with the corresponding hole in the bottom surface of the ring groove, and the gear teeth are fixed with the gear ring through hinge pins. According to the large gear structure of the cement mixer, every gear tooth can be fabricated separately, thereby being simple in fabricating process and meanwhile having the advantage of relatively low cost.

Description

technical field [0001] The invention relates to a large gear structure, which belongs to the technical field of cement mixers, and specifically relates to a large gear structure of a cement mixer. Background technique [0002] At present, the large gear installed on the outer circle of the cement mixer drum is an integral structure, and it is also an important part of the cement mixer. However, because the working environment of the cement mixer is generally relatively harsh, the degree of wear of the large gear is average. Larger, so the service life of the large gear is relatively low. Once the large gear wears to a certain extent, it must be replaced. Therefore, the use cost of the cement mixer is relatively high. At the same time, because the existing large gear is an integral In the structural form, if one of the teeth is damaged, the entire large gear will have to be scrapped, which further increases the cost of use. In addition, due to the large diameter and parameter...
