Description

Technical Field

[0001] This utility model specifically relates to the field of drive shaft box technology, and more specifically to a drive shaft box that is easy to install. Background Technology

[0002] A driveshaft housing is a mechanical component used to protect and support a driveshaft. The driveshaft is a key component in a power transmission system; its main function is to transmit power generated by an engine or power source to components requiring power. It generally consists of a housing, driveshaft, bearings, and transmission components, most of which are gear sets. Power is transmitted through the meshing of these gear sets.

[0003] However, in practice, it has been noted that when assembling the internal gear set and shaft, the gear set needs to be placed inside the housing first, and then the shaft needs to be inserted from the end of the housing. During the insertion process, the gear set also needs to be installed onto the shaft. Due to the relatively narrow space inside the housing, the installation takes a lot of time and effort. Furthermore, bearings are needed to fix the shaft and housing. Since the bearings use an interference fit, the installation is cumbersome and takes a lot of time. Utility Model Content

[0004] The purpose of this invention is to provide a transmission shaft box that is easy to install. Utilizing a split-type housing, it facilitates the installation of internal shafts and gear sets. Furthermore, the interlocking of arc-shaped threaded posts, positioning posts, and locking nuts on both sides improves the stability of the installed shafts. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drive shaft box that is easy to install includes a fixed housing and a removable cover that are interlocked with each other. The fixed housing and the removable cover are fixedly connected by locking screws on both sides, and the ends of the locking screws pass through the removable cover and are threadedly connected to the fixed housing.

[0007] The inner side of the fixed box is symmetrically fixed with supporting ribs, and the two ends of the fixed box and the supporting ribs are respectively provided with corresponding shaft holes. An input shaft is installed on the inner side of the fixed box, and an input pulley is fixedly connected to the end of the input shaft through the shaft hole.

[0008] As a further technical solution of this utility model, the end of the input shaft extends to the end of the fixed housing, and the input pulley is located at the end of the fixed housing. Moreover, an interference fit is provided between the input shaft and the shaft hole to install a bearing.

[0009] As a further technical solution of this utility model, an output shaft and a transmission shaft are respectively installed on the inner side of the fixed housing, and both ends of the output shaft and the transmission shaft pass through shaft holes, wherein one end of the output shaft extends to the end away from the fixed housing of the input pulley.

[0010] As a further technical solution of this utility model, the disassembly cover has an L-shaped shell covering the outside of the fixed box body. Positioning baffles are fixedly connected in a rectangular array in the L-shaped shell body, and the positioning baffles correspond to the two sides of the fixed box body and the supporting ribs respectively.

[0011] As a further technical solution of this utility model, the positioning baffle is provided with a shaft positioning groove corresponding to the shaft hole, and the shaft hole and the positioning baffle together form a circular hole. Each of the circular holes is equipped with a support bearing, and the inner ring of the support bearing is interference-fitted with the output shaft and the transmission shaft respectively.

[0012] As a further technical solution of this utility model, both ends of the fixed box are integrally provided with positioning posts, and the sides of the positioning baffles at both ends of the L-shaped shell are integrally provided with arc-shaped threaded posts corresponding to the positioning posts. The bottom of the arc-shaped threaded posts is provided with notches, the shape of which is the same as that of the positioning posts, and the positioning posts are attached to the bottom of the arc-shaped threaded posts.

The fixed housing and detachable cover are respectively provided with shaft holes for fixing the output shaft and shaft positioning grooves. After opening the fixed housing and detachable cover, the output shaft and the gear set on the output shaft can be directly removed, which also makes it more convenient to install.

[0016] 2. In this utility model, the supporting ribs in the fixed housing and the positioning baffles in the detachable housing cover cooperate with each other to support the output shaft and transmission shaft installed on the inner side, and also separate the multiple gear sets. The separate space can reduce the mutual contamination of lubricating oil and extend the service life.

[0017] 3. This utility model uses positioning posts and arc-shaped threaded posts correspondingly set on both sides of the fixed box and the L-shaped shell for positioning, and performs edge locking at the connection between the fixed box and the L-shaped shell to ensure that the connection locks the input pulley, output shaft and transmission shaft, and prevents the vibration generated during use from affecting the stability of the input pulley, output shaft and transmission shaft during use.

Positioning baffles 23 are fixedly connected in a rectangular array in the L-shaped shell 21, and the positioning baffles 23 correspond to the two sides of the fixed box 1 and the supporting ribs 7 respectively.

[0035] By adopting the above technical solution, the fixed housing 1 and the detachable cover 2 are designed to be split open, which makes it easy to open the transmission shaft box. The fixed housing 1 and the detachable cover 2 are respectively provided with shaft hole 8 for fixing output shaft 4 and shaft positioning groove 24. After opening the fixed housing 1 and the detachable cover 2, the output shaft 4 and the gear set 6 on the output shaft 4 can be directly removed, which also makes it more convenient to install them.

[0036] Furthermore, the positioning baffle 23 is provided with a shaft positioning groove 24 corresponding to the shaft hole 8, and the shaft hole 8 and the positioning baffle 23 together form a circular hole. Each of the circular holes is equipped with a support bearing, and the inner ring of the support bearing is interference-fitted with the output shaft 4 and the transmission shaft 5 respectively.

[0037] More specifically, both ends of the fixed housing 1 are integrally provided with positioning posts 9, and the sides of the positioning baffles 23 at both ends of the L-shaped housing 21 are integrally provided with arc-shaped threaded posts 22 corresponding to the positioning posts 9.
