Description

Technical Field

[0001] The present invention relates to an installation structure and a usage method of an angular gearbox, belonging to the technical field of gearbox positioning tooling. Background Art

[0002] An angular gearbox is a special device for changing the power transmission direction between two shafts. At present, angular gearboxes are widely used in various mechanical transmission systems. Most traditional angular gearboxes are of an integral structure and are usually installed on main and auxiliary beams by means of bolt fastening. During the processing of the main and auxiliary beams, it is inevitable to generate form and position errors, which are difficult to meet the installation accuracy of the angular gearbox, resulting in an increase in the noise of the angular gearbox during power transmission, and aggravating the wear of the transmission pair, causing it to fail prematurely, bringing unnecessary economic losses to manufacturers and users. Summary of the Invention

[0003] The purpose of the present invention is to provide an installation structure and a usage method of an angular gearbox. By installing the angular gearbox through a middle swing shaft fixing device and an eccentric correction device, on the basis of being able to slightly change the position of the angular gearbox, the installation accuracy of the angular gearbox can also be met, and the problems in the background art can be solved.

[0004] The technical solution of the present invention is as follows:

[0005] An installation structure of an angular gearbox includes a middle swing shaft fixing device, an eccentric correction device, an angular gearbox, and an installation housing. The outer shape of the installation housing matches the outer shape of the angular gearbox, and both ends of the installation housing are open; the angular gearbox is arranged in the installation housing through a group of middle swing fixing devices, and the angular gearbox can swing around the middle axis in the installation housing; an eccentric correction device is provided between the angular gearbox and the installation housing, and micro eccentric correction is performed through the eccentric correction device to slightly correct the installation position of the angular gearbox.

[0006] Further, a group of middle swing fixing devices consists of two symmetrically arranged middle swing fixing devices. The middle swing fixing device includes a first cylindrical hole, a first shaft, and a first flange. The first cylindrical hole is welded on the outer side of the angular gearbox housing. A first shaft hole is provided on the housing wall of the installation housing, and a first annular boss is provided on the outer edge of the first shaft hole. The first flange is fixed on the first annular boss by screws, and one end of the first shaft concentric with the first flange is fixed on the first flange, and the other end of the first shaft penetrates through the first shaft hole and extends into the first cylindrical hole.

[0007] Further, the eccentric correction device is composed of a second cylindrical hole, a second shaft, and a second flange. The second cylindrical hole is welded to the outer side of the angular gearbox housing. There is a second shaft hole on the wall of the installation housing. There is a second annular boss along the outer edge of the second shaft hole. The second flange is fixed to the second annular boss by screws. One end of the second shaft eccentrically arranged with the second flange is fixed to the second flange, and the other end of the second shaft penetrates through the second shaft hole and extends into the second cylindrical hole; a plurality of arc-shaped counterbores are uniformly arranged along the circumferential direction of the second flange, and the screws penetrate through the arc-shaped counterbores and are threadedly connected to the bolt holes on the second annular boss.

[0008] Further, the installation housing is formed by bending and welding a first housing and a second housing. A set of middle pendulum fixing devices is arranged in the first housing, and the eccentric correction device is arranged in the second housing.

[0009] The angular gearbox is a well-known and commonly used structure in the art.

[0010] The usage method of the above angular gearbox installation structure is as follows: The angular gearbox is slightly eccentrically corrected through the eccentric correction device to slightly correct the installation position of the angular gearbox.

[0011] Further, the more specific operation steps are as follows: Rotate the second flange, driving the second shaft to rotate along the arc-shaped counterbore. Since the second shaft is eccentrically arranged with the second flange, when the second shaft rotates, it will also have a slight eccentric displacement, thereby driving the angular gearbox to have a slight eccentric displacement, achieving the slight eccentric correction of the angular gearbox.

[0012] The positive effects of the present invention: The present invention provides an installation housing outside the original angular gearbox. The angular gearbox is connected to the installation housing through a set of middle pendulum fixing devices. The angular gearbox can swing within the installation housing. An eccentric correction device is also provided between the angular gearbox and the installation housing. Through the eccentric correction device, slight eccentric correction is performed to slightly correct the position of the angular gearbox, ensuring that the angular gearbox has a high installation accuracy, effectively reducing the noise during the use of the angular gearbox, and reducing the wear of the transmission pair, thereby reducing the cost.

The middle swing fixing device 1 includes a first cylindrical hole 101, a first shaft 102, and a first flange 103. The first cylindrical hole 101 is welded to the outer side of the housing of the angular gearbox 3. A first shaft hole is provided on the wall of the first housing, and an annular boss 104 is provided on the outer edge of the first shaft hole. The first flange 103 is fixed to the annular boss 104 by screws. One end of the first shaft 102 concentrically arranged with the first flange 103 is fixed to the first flange 103, and the other end of the first shaft 102 penetrates the first shaft hole and extends into the first cylindrical hole 101 for shaft hole matching.

[0024] Refer to the attached Figure 3 , in this embodiment, the first flange 103 and the first shaft 102 are concentrically arranged, and the end of the first shaft 102 is fixed to the first flange 103 to form a concentric shaft structure at the flange end.

[0025] In a set of middle swing shaft fixing devices 1, the first flange 103 of the concentric shaft structure of the two flange ends is fixed to the annular bosses 1 on both sides of the first housing by screws respectively. The shaft head part of its first shaft 102 passes through the central through hole of the annular boss 1 and is in shaft-hole fit with the first cylindrical holes on both sides of the same end of the angular gearbox 3, so that the angular gearbox 3 forms a stable support structure for the middle swing shaft through a set of middle swing shaft fixing devices 1.

[0026] Preferably, the eccentric correction device 2 is composed of a second cylindrical hole 201, a second shaft 202 and a second flange 203. The second cylindrical hole 201 is welded to the outer side of the housing of the angular gearbox 3. A second shaft hole is provided on the housing wall of the second housing, and an annular boss 204 is provided on the outer edge of the second shaft hole. The second flange 203 is fixed to the annular boss 204 by screws. One end of the second shaft 202 eccentrically arranged with the second flange 203 is fixed to the second flange 203, and the other end of the second shaft 202 passes through the shaft hole and extends into the second cylindrical hole 201 for shaft-hole fit; a plurality of arc-shaped counterbores 205 are uniformly arranged on the second flange 203 along the circumferential direction. After the screws pass through the arc-shaped counterbores 205, they are threadedly connected to the bolt holes on the annular boss 204.

[0027] Refer to the appendix Figure 4 In this embodiment, the second flange 203 and the second shaft 202 are arranged non-concentrically, the second shaft 202 is slightly offset radially, and the end of the second shaft 202 is fixed to the first flange 103, constituting a non-concentric and slightly offset shaft head structure of the flange end.

[0028] On the second flange 203 of the non-concentric and slightly offset shaft head structure of the flange end, a plurality of arc-shaped counterbores 205 are uniformly distributed along the circumferential direction.

[0029] In this embodiment, a support structure with two concentric shaft structures of the flange ends and a correction structure with a non-concentric and slightly offset shaft head structure of the flange ends are used to make a slight adjustment to the installation position of the angular gearbox. The eccentricity of the non-concentric and slightly offset shaft head structure of the flange ends is set according to actual applications.

[0030] A usage method of an angular gearbox installation structure is as follows: The angular gearbox 3 is slightly eccentrically corrected through the eccentric correction device 2 to slightly correct the installation position of the angular gearbox 3.

[0031] The specific operation method is as follows: By rotating the second flange 203, the overall structure of the eccentric offset shaft head with non-concentric flanges can rotate along the arc-shaped counterbore 205. Since the second shaft 202 and the second flange 203 are eccentrically arranged, while the second shaft 202 rotates, it will also have a small eccentric displacement, thereby driving the angular gearbox 3 to have a small eccentric displacement, achieving the small eccentric correction of the angular gearbox 3, enabling the angular gearbox 3 to have accurate positioning and installation accuracy, and thus ensuring the transmission accuracy of the angular gearbox 3.
