Description

Technical Field

[0001] The present invention relates to a bearing seat device with an improved structure, which is preferably used in an automobile gearbox. The bearing seat device can change the direction of the rotation axis of the bearing by adjusting its own installation angle, so as to compensate for the irregular deformation of the housing shaft. Background Art

[0002] In automobile gearboxes, bearings are core parts. Precise installation of bearings can ensure the normal operation of rotating parts. Bearings in gearboxes are generally installed between the housing and the shaft through loose fit and / or tight fit. Most bearing seats can only adjust the axial positioning surface by adjusting the gasket, but the radial distance between the bearing seat and the bearing can only be guaranteed by the machining accuracy and cannot be adjusted. In some high-precision application scenarios, the bearing seat can adopt an independent installation structure, and the radial distance can be adjusted through the bolt hole.

[0003] A bearing seat capable of adjusting the concentricity of two bearing seats is known from CN106939921A, comprising an adjustable bearing seat, a fixed bearing seat, a connecting block, a first adjusting block and a second adjusting block. The adjustable bearing seat and the fixed bearing seat are fixed by welding through the connecting block, an arc-shaped stabilizing block is welded to the top of the adjustable bearing seat, through holes are respectively arranged at the inner ends of the adjustable bearing seat, rectangular grooves communicating with the through holes are respectively arranged at the bottom ends of the adjustable bearing seat, female threads are arranged inside the through holes, an adjusting screw is welded on one side of the first adjusting block, and an adjusting head is arranged at one end of the adjusting screw. By dividing the bearing seat into a fixed bearing seat and an adjustable bearing seat, and arranging the first adjusting block and the second adjusting block, the two adjusting blocks are relatively matched, thereby achieving the function of adjusting the concentricity of the bearing inside the adjustable bearing seat, and realizing the adjustment of the concentricity of the bearing.

[0004] It can be seen that the adjustable bearing seat in the prior art can usually only be adjusted in translation on the installation plane, does not have an angle compensation function, and cannot achieve a rotation adjustment function. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an improved adjustable bearing seat device, which can overcome the shortcomings of the prior art and realize the rotation adjustment function of the bearing.

[0006] The adjustable bearing seat device designed according to the present invention comprises: a bearing seat, a bearing, a base and a shell, wherein the base is fixedly mounted on the shell, the bearing seat is arranged on the base, and the bearing seat supports the bearing, wherein the base has a first joint surface engaged with the shell and a center hole for arranging the bearing seat, wherein the center hole has a center axis, and the first joint surface is perpendicular to the center axis, wherein the base has a second joint surface engaged with the bearing seat, and the second joint surface is an inclined surface, forming a first angle with the center axis. The technical effect of implementing the present invention is that the joint surface between the base and the bearing seat adopts an inclined surface design, which can adjust the angle of the rotation axis of the bearing, thereby adapting to different application requirements and realizing the rotation adjustment function of the bearing.

[0007] According to a preferred embodiment of the present invention, the base has an annular first rim, and a plurality of uniformly distributed first fastening holes are provided in the circumferential direction around the base. This design enables the base to be fixed on the housing through different fastening hole positions for rotation adjustment. It is further preferred that the bearing seat has a third engagement surface for engagement with the bearing. At the same time, the bearing seat also has a rotation axis, and the third engagement surface is an inclined surface, and forms a second angle β with the rotation axis. Due to the inclined design of the third engagement surface, the bearing seat can adjust the angle within a certain range to adapt to different adjustment requirements. Further, the bearing seat designed according to the present invention has an annular second rim, and a plurality of uniformly distributed second fastening holes are provided in the circumferential direction around the bearing seat. This enables the bearing seat to be connected to other components through fastening holes at different positions to adapt to a variety of assembly situations. It is further preferred that the second fastening hole is an annular groove, that is, an elongated hole extending along the circumferential direction. This design can increase the adjustment range and ensure the adjustability of the device. It can also be considered that the second angle β is greater than the first angle α, which means that the device can be adjusted in a wider range, making it suitable for a wider range of application scenarios. In addition, it is also possible to consider such a design that the second angle β is equal to the first angle α, so that the first joint surface and the third joint surface have a considerable inclination angle, so that the angles can be complementary or superimposed on each other, so that the angle adjustment can be performed between 0-2α. Furthermore, when the design requirements of the bearing seat and the base are not required, after the assembly is completed, the central axis coincides with the rotation axis of the bearing, which ensures that the use environment of the device is wider, and it is easier to make the rotation axis coincide with the central axis when no adjustment is required.

[0008] In summary, the present invention provides an adjustable bearing seat device, which can adapt to different application requirements by adjusting the engagement angle between the base and the bearing seat, thereby making the device more flexible and applicable.

[0009] In addition, the bearing seat device with the above characteristics can be used in a transmission, for example, on a reduction box housing, and by using the bevel fit, the bearing rotation angle can be adjusted. It is suitable for a reduction box housing with irregular deformation, which is conducive to the smooth operation of the bearing. In addition, the technical solution described in the present invention can also be applied to a vehicle, which includes a transmission with a bearing seat device with the above characteristics. This bearing seat device can achieve stepless adjustment of the angle deviation between the rotation axis of the bearing and the central axis, has a compact overall size, high reliability of the full mechanical structure, and has cost advantages.

[0014] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0015] Figure 1The exploded view of the adjustable bearing seat device designed according to the present invention is shown. The adjustable bearing seat device includes: a bearing seat 1, a bearing 2, a base 3 and a housing 4. According to an embodiment of the present invention, the bearing seat device is placed in a gearbox of a vehicle, so the housing 4 can be a housing of the gearbox, and the gearbox shaft is supported by the bearing 2. The base 3 is fixedly mounted on the housing 4, and the bearing seat 1 is placed on the base 3. The base 3 has a first engagement surface 31 engaged with the housing 4 and a second engagement surface 32 engaged with the bearing seat 1, and the second engagement surface 32 is an inclined surface. The base 3 also has an annular first rim 33 for fixing on the housing, and a plurality of first fastening holes 34 are arranged on the first rim 33. Due to the annular edge, the inclination angle of the inclined surface of the second engagement surface 32 can be adjusted in the circumferential direction. The bearing seat 1 has a third engagement surface 11 engaged with the bearing 2, and the bearing seat 1 has an annular second rim 13, and a plurality of second fastening holes 14 are arranged on the second rim 14, and the second fastening holes 14 are especially elongated holes, so as to be used to more easily rotate and fix the bearing seat 1.

[0016] like Figure 2 As shown, there is a first angle α between the first joint surface 31 and the second joint surface 32, and there is a second angle β between the third joint surface 11 and the second joint surface 32. The first rotation axis 12 of the bearing seat 1 is perpendicular to the second joint surface 32. The bearing 2 has a rotation axis, and the transmission shaft of the gearbox has a rotation axis 35, wherein the rotation axis 35 is also the central axis 35 of the base 3. The first joint surface 31 is perpendicular to the rotation axis 15, and the second joint surface 32 is the joint surface between the base 3 and the bearing seat 1, which is designed as an inclined surface. The third joint surface 11 fits with the second joint surface 32 after assembly, and the third joint surface is the inclined surface of the bearing seat 1. As shown Figure 2 As shown in , if rotation adjustment is not required, β = α can be set, or a bearing seat with an angle of α can be selected to match a base with an angle of α. Figure 2 After the assembly is completed in this way, the second rotation axis 22 of the bearing coincides with the central axis 35, that is, no rotation adjustment is performed.

[0017] Figure 3 The figure shows a process of rotation adjustment. Since the bearing seat 1 and the base 3 are connected by the second ring edge 13, they can be rotated to an appropriate angle and then fixed, that is, the angle can be adjusted steplessly. The angle between the second rotation axis 22 of the bearing and the central axis 35 of the base is set as the third angle γ, and the inclined surfaces of the base and the bearing seat are adjusted according to the angle γ. If β=α is set, then Figure 3As shown, the maximum inclination angle can be adjusted to 2α, that is, the maximum angle γ=2α between the second rotation axis 22 and the central axis 35. If the first joint surface 31 and the second joint surface 32 have a first angle α, and the third joint surface 11 and the second joint surface 32 have a second angle β, then after assembly, the range of the third angle γ is α-β≤γ≤α+β.

[0018] Although possible embodiments are described by way of example in the above description, it should be understood that there are still a large number of variations of embodiments through the combination of all known and easily conceivable technical features and embodiments by the skilled person. It should also be understood that the exemplary embodiment is only an example and that such embodiment in no way limits the scope of protection, application and configuration of the present invention. The foregoing description is more to provide a technical guide for converting at least one exemplary embodiment to the skilled person, wherein various changes can be made, especially changes in the functions and structures of the components, as long as they do not depart from the scope of protection of the claims.
