AI Technical Summary
Dust can easily enter the bearing housing at the slag discharge drum end of the bucket wheel excavator, causing the bearing to become sluggish, potentially leading to seizure, increasing maintenance frequency and costs.
The bearing housing is completely sealed inside the bucket wheel arm. By setting a cavity inside the bucket wheel arm and forming a seal between the drum shaft and the sealing ring, dust is prevented from entering.
It effectively prevents dust intrusion, extends the service life of bearing housings and rollers, reduces maintenance frequency, and improves equipment lifespan and production efficiency.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing housing technology, specifically referring to a bearing housing mounting structure. Background Technology
[0002] In the field of mechanical transmission, bearing housings are key components used to support and fix bearings. They provide a stable working environment for the bearings, ensuring they can withstand axial and radial loads and allowing rotating components such as shafts to rotate smoothly. Bearing housings are widely used in various types of mechanical equipment, such as bucket wheel excavators, and play a vital role in the normal operation of the equipment.
[0003] In the working system of a bucket wheel excavator, the slag discharge drum is a crucial component. In traditional designs, the slag discharge drum is typically installed on the outer side of the bucket wheel arm. However, this installation method has significant drawbacks in practical applications. The working environment of a bucket wheel excavator is often dusty, and during operation, a large amount of dust can easily enter the bearing housing at the end of the slag discharge drum. This dust intrusion interferes with the normal lubrication of the bearing, causing uneven rolling between the bearing housing and the drum, and in severe cases, even jamming. Once this occurs, it not only damages the bearing housing and drum shaft but also forces the equipment to be shut down for maintenance, significantly increasing maintenance frequency and costs, resulting in unnecessary economic losses for the company. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a bearing housing mounting structure.
[0005] The technical solution adopted by this utility model is as follows: This utility model provides a bearing seat mounting structure, including a bucket wheel arm, the bucket wheel arm has a cavity inside, a bearing seat is fixedly installed on the inner wall of the cavity, a bearing is fixedly installed inside the bearing seat, and the inner ring of the bearing is fixedly sleeved on the roller shaft.
[0006] Furthermore, a slag discharge roller is fixedly sleeved on the roller shaft.
[0007] Furthermore, a sealing ring is installed on the outer wall of the bucket wheel arm, and the sealing ring is rotatably sleeved on the drum shaft.
[0008] Furthermore, the bucket wheel arm is provided with reinforcing ribs.
[0009] Furthermore, the sealing ring is used to prevent dust from entering the bucket wheel arm.
[0010] The beneficial effects of this utility model by adopting the above structure are as follows:
[0011] By completely sealing the bearing housing inside the bucket wheel arm, the damage caused by dust to the bearing housing can be directly eliminated, the service life of the slag discharge roller can be extended, and the maintenance and upkeep of the slag discharge roller can be reduced, thereby improving the service life and working time of the bucket wheel machine and increasing production efficiency.

[0017] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0018] like Figures 1-3 As shown, this utility model proposes a bearing housing installation structure, including a bucket wheel arm 1, a reinforcing rib inside the bucket wheel arm 1, a cavity inside the bucket wheel arm 1, a bearing housing 3 fixedly installed on the inner wall of the cavity, a bearing 6 fixedly installed inside the bearing housing 3, a roller shaft 4 fixedly sleeved on the inner ring of the bearing 6, a slag discharge roller 2 fixedly sleeved on the roller shaft 4, and a sealing ring 5 installed on the outer wall of the bucket wheel arm 1. The sealing ring 5 is rotatably sleeved on the roller shaft 4 and is used to prevent dust from entering the bucket wheel arm 1.
[0019] In practical use, the bucket wheel arm 1 has an internal cavity with sufficient sealing space to fix the bearing seat 3 in the slag discharge drum 2 inside the cavity. A sealing ring 5 is set at the intersection of the drum shaft 4 and the bucket wheel arm 1, so that the bearing seat 3 is completely in a sealed space, reducing the contact between the bearing seat 3 and external dust, thereby achieving the best use effect. The above is the overall working process of this utility model. This step can be repeated for the next use.
[0020] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
