CN206539690U - A kind of removable drive chain roller box combination - Google Patents

Abstract

The utility model relates to a drive sprocket box combination, in particular to a convenient detachable drive sprocket box combination. It is characterized in that welding is replaced by bolt connection, that is, the combined sprocket box housing is connected by 6 M4 ordinary bolts (1), and the design is simple and practical. The sprocket box is mainly composed of clutch shaft, bearing, sprocket, sleeve roller chain, etc. The main working features are: the clutch shaft (3) is supported by the bearing (2), the shaft (3) and the driving sprocket (4) Linked to each other, the chain (5) is installed on the sprocket (4), when external force drives, the torque can be transmitted to the chain through the shaft, thereby driving other parts to work. The positive effect of the utility model is that the problems of broken chains, loose or damaged internal parts of the sprocket box and inconvenient disassembly and maintenance are well solved, and the utility model is economical and environmentally friendly.

Description

A detachable drive sprocket box combination

technical field

The utility model relates to a drive sprocket box combination, in particular to a convenient and detachable drive sprocket box combination, which belongs to the technical field of mechanical manufacturing.

Background technique

Rice is one of the three major food crops in my country, and its planting area accounts for about one-third of the total area of food crops in my country. Therefore, rice occupies an extremely important position in my country's national economy. However, the problem of rice mechanized planting has increasingly become the bottleneck of agricultural production mechanization and the main obstacle restricting the development of agricultural mechanization in my country. Therefore, the requirements for the use of rice transplanters are getting higher and higher.

At present, the drive sprocket box of the rice transplanter has been using the previous design, and the shell adopts the method of multi-point welding. When the chain inside the box jumps, breaks, and parts are worn, loose or damaged, it becomes very difficult to replace and maintain. Affects the efficiency of use, so it needs to be improved.

Utility model content

1. This utility model designs a convenient and detachable combination box. The power assembly of the front clutch device of the rice transplanter engine gearbox is made into an open structure, and the bolt connection method is used instead of welding. The main features are: combination sprocket The box shell is connected by 6 M4 ordinary bolts, the design is simple and practical, it is easy to repair and replace the transmission chain, reduce the use cost and improve the use efficiency.

2. The utility model is composed of clutch shaft, bearing, sprocket, sleeve roller chain, etc. The main working features are: the clutch shaft is supported by the bearing, the shaft is connected with the driving sprocket, and the chain is installed on the sprocket. When driving, the torque can be transmitted to the chain through the shaft, thereby driving other components to work.

3. Adopting the above scheme can solve the shortcomings of inconvenient maintenance such as chain jumping, breakage, loose parts or damage inside the box, and improve labor productivity.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

The accompanying drawing 1 of the description is a schematic diagram of the overall structure of the utility model, and Figure 2 is a schematic diagram of the internal transmission of the utility model.

Among Fig. 2, 1, M4 ordinary bolt, 2, deep groove ball bearing, 3, clutch shaft, 4, driving sprocket wheel, 5, sleeve roller chain.

detailed description

A detachable drive sprocket box combination as shown in Figure 2 of the specification, the box body is connected by a group of M4 ordinary bolts (1), the deep groove ball bearing (2) supports the clutch shaft (3), and the clutch shaft ( 3) It is connected with the driving sprocket (4) and transmits torque, and the sleeve roller chain (5) is connected with the driving sprocket (4). The chain drive is suitable for the distance between the two shafts, and can be used under harsh conditions such as high temperature and high humidity, and is widely used in the field of agricultural machinery.

Claims (2)

1. A convenient and detachable drive sprocket combination box, characterized in that: the combination sprocket box shell is connected by 6 M4 ordinary bolts, and the power assembly of the front clutch device of the rice transplanter engine gearbox is made into an open structure . 2. A kind of convenient detachable drive sprocket combination box as claimed in claim 1, the box body is connected by 6 M4 ordinary bolts (1), and the deep groove ball bearing (2) supports the clutch shaft (3), The clutch shaft (3) is connected to the driving sprocket (4) and transmits torque, and the sleeve roller chain (5) is connected to the driving sprocket (4), and finally transmits the torque to the chain through the shaft, thereby driving other components to work .
