Description

Technical Field

[0001] The utility model relates to the field of mining equipment, in particular to a built-in clutch of a special reducer for vertical shaft mining transportation. Background Art

[0002] Belt conveyor is a continuously running transport equipment, a modern large-scale transport equipment with high strength, large transport capacity and high power. It plays an important role in heavy industrial sectors such as metallurgy, mining, power, building materials and transportation sectors. With the increasing shortage of energy in the world, coal mining is imminent. However, belt conveyor is the most ideal high-efficiency continuous transport equipment for coal mines. Compared with other transport equipment, it not only has the advantages of long distance, large transport capacity and continuous transport, but also has reliable operation and is easy to realize automation and centralized control. Especially for high-yield and high-efficiency mines, belt conveyor has become a key equipment for mechatronic technology and equipment for efficient coal mining.

[0003] Disadvantages of vertically mounted reducer:

[0004] 1. Limited by installation conditions: Since the motor and reducer of the vertically mounted reducer are arranged vertically, the limitations of installation conditions, such as installation height and space, need to be considered during installation.

[0005] 2. When the reducer is under high load and long-term continuous operation, the reducer is prone to temperature rise. If the heat dissipation is poor, it may cause thermal expansion and increased wear of the internal parts of the reducer, thus affecting the performance and life of the reducer.

[0006] 3. Due to the harshness of the mining environment, the reducer needs regular maintenance and servicing to ensure its normal operation. However, the maintenance and servicing work is often limited by many factors such as mining conditions and personnel skills, making it difficult to be timely and effective. Utility Model Content

[0007] In view of the above problems existing in the existing vertical shaft mine conveying special reducer, the present utility model is proposed.

[0008] Therefore, the purpose of the utility model is to provide a built-in clutch of a special speed reducer for vertical shaft mining transportation, which solves the problems raised by the background technology.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A built-in clutch of a special reducer for vertical shaft mining transportation, comprising a reducer housing and a gear shaft, a bevel gear and a ball-type one-way clutch arranged inside the reducer housing, wherein the gear shaft is vertically arranged inside the reducer housing, the bevel gear is located on the shaft wall of the gear shaft, and the ball-type one-way clutch is arranged between the inner wall of the bevel gear and the shaft wall of the gear shaft; blind covers are provided on both sides of the reducer housing and at positions corresponding to the positions of the gear shaft, an adjustment ring is provided on the inner side surface of the blind cover, and the end of the gear shaft extends to the interior of the adjustment ring and is rotatably connected through a bearing.

[0011] Preferably, a pressure cover is provided between the ball-type one-way clutch and the bevel gear.

[0012] Preferably, the gland and the bevel gear are fixedly connected by bolts.

[0013] Furthermore, both ends of the gear shaft are provided with distance rings, and the distance rings are provided in contact with the inner wall of the bearing.

[0014] Preferably, the shaft wall of the gear shaft is provided with a positioning flat key.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. Compact structure: Since the built-in clutch is directly connected to the reducer, the overall structure is more compact, which reduces the complexity of the equipment and the number of parts and improves the overall reliability of the equipment.

[0017] 2. Space optimization: The built-in clutch is directly integrated into the reducer, without the need for additional external space, thus effectively saving the installation space of the overall equipment. This is a very important advantage for mining conveying equipment, especially in space-constrained environments.

[0018] 3. Reduce costs: The design of built-in clutch helps to reduce equipment manufacturing costs, because the integrated design can reduce material consumption and processing costs. At the same time, the reduction in maintenance costs also helps to reduce the overall equipment cost.

[0019] 4. Easy maintenance: The design of built-in clutch makes maintenance easier because all parts are concentrated in one place for easy inspection and maintenance. In addition, due to the reduction of external connections and interfaces, the error and failure rate during maintenance is also reduced. BRIEF DESCRIPTION OF THE DRAWINGS
