Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of reducer components, specifically a lightweight reducer housing, which is mainly used for mounting various transmission components of the reducer. Background Technology
[0002] The reducer housing is one of the most important components of a reducer. It is mainly used to install various transmission parts of the reducer. Traditional reducer housings are mainly made of cast iron, which makes them relatively heavy and results in relatively poor adaptability to use.
[0003] To achieve lightweight design of reducer housings, the current approach is to replace the entire cast iron reducer housing with an aluminum alloy one. While this reduces the overall weight, it significantly increases manufacturing costs. Furthermore, aluminum alloy reducer housings suffer from insufficient rigidity, resulting in inadequate NVH (noise, vibration, and harshness) performance, which is quite problematic. In practical use, existing reducer housings also suffer from fixed and non-adjustable installation positions / angles, making them unsuitable for installing transmission components of different specifications and gear ratios, thus resulting in relatively low adaptability.
[0004] Therefore, the research objective of this utility model is to design a lightweight reducer housing that can effectively maintain the overall rigidity of the reducer housing, keep the overall weight of the reducer housing at a low level, and effectively realize the adjustable setting of the installation position of the transmission components, so as to effectively adapt to the installation of transmission components of different specifications and transmission ratios. Summary of the Invention
[0005] In view of the technical problems existing in the prior art, the present invention provides a lightweight reducer housing, which can effectively solve the technical problems existing in the prior art.
[0006] The technical solution of this utility model is: A lightweight reducer housing, comprising: A set of high-strength frames includes a first bearing mounting seat, which is provided with a corresponding first bearing mounting hole. A corresponding second bearing mounting seat is installed at an adjustable angle on the rear side of the first bearing mounting seat, which is provided with a corresponding second bearing mounting hole. A corresponding third bearing mounting component is installed at an adjustable angle on the front side of the first bearing mounting seat, which is provided with a corresponding third bearing mounting hole. Several locking components are used to lock and fix the second bearing mounting base and the third bearing mounting component, after the angle adjustment is completed, onto the first bearing mounting base respectively. A lightweight outer shell is disposed around a set of high-strength frames. The opposite sides of the set of high-strength frames are respectively fixedly embedded in the inner sidewall of the lightweight outer shell. The locking ends of the locking assemblies are respectively embedded and fixed inside the lightweight outer shell.
[0007] The locking assembly includes a fixing plate fixed to the first bearing mounting seat and a locking plate fixed to the second bearing mounting seat and the third bearing mounting component. The fixing plate and the locking plate are respectively provided with a plurality of corresponding connecting holes. The relative positions of the fixing plate and the locking plate are adjusted so that the connecting holes on the fixing plate and the locking plate overlap. Then, the corresponding locking bolts are fixedly inserted between the connecting holes of the fixing plate and the locking plate and the locking bolts are fixed and locked by the corresponding locking nuts.
[0008] The high-strength frame is made of steel, and the lightweight outer shell is integrally cast from aluminum alloy on the outside of the high-strength frame. The locking nuts and locking bolts are respectively embedded and fixed inside the lightweight outer shell.
[0009] The fixed plates are integrally formed in a stepped shape and connected to the first bearing mounting base. The locking plates are integrally formed in a stepped shape and connected to the second bearing mounting base and the third bearing mounting component. The locking plates are connected to the corresponding fixed plates by an inner and outer overlapping method. The locking bolts and locking nuts are then used to fix the locking plates and fixed plates after the connection is completed.
[0010] The front end of the lightweight outer shell is provided with a transmission component assembly hole, and the third bearing mounting hole of the third bearing mounting component extends to the outside of the transmission component assembly hole.
[0011] The lightweight outer shell has a through hole for the main cone shaft to extend through. The second bearing mounting seat of the high-strength frame on the side away from the through hole is spaced apart from the first bearing mounting seat, and a corresponding pad is fixedly placed at the gap between the second bearing mounting seat and the first bearing mounting seat. The pad is provided with a guide hole corresponding to the connection hole of the fixing plate and the locking plate. The locking bolt passes through the connection hole of the fixing plate and the locking plate and the guide hole of the pad and is then fixed and locked by the locking nut.
[0012] The first bearing mounting base is provided with at least one corresponding weight reduction hole.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1) This utility model uses several locking components to lock and fix the second bearing mounting seat and the third bearing mounting component, after angle adjustment, onto the first bearing mounting seat. Finally, a lightweight outer shell is placed around a set of high-strength frames, with opposite sides of the high-strength frames fixedly embedded in the inner wall of the lightweight outer shell. The locking end of the locking components is then embedded and fixed by the lightweight outer shell. In use, the intermediate shaft bearing, input shaft bearing, and output shaft bearing are installed in their respective positions on the first bearing mounting seat, second bearing mounting seat, and third bearing mounting component, and then the transmission components are installed. The lightweight outer shell and the high-strength frames work together to maintain the overall rigidity of the reducer housing while effectively keeping the overall weight of the reducer housing at a low level. Moreover, the adjustable angle between the second bearing mounting seat, the third bearing mounting component, and the first bearing mounting seat allows for adjustable installation positions of the transmission components, effectively adapting to the installation of transmission components of different specifications and transmission ratios, thus greatly improving the adaptability of this utility model.
[0014] 2) While the adjustable angle installation of the second bearing mounting base, the third bearing mounting component, and the first bearing mounting base can effectively accommodate the installation of transmission components of different specifications and transmission ratios, the locking stability of the locking assembly used for connection and fixation will loosen as the reducer operates for an extended period of time. This results in the connection stability between the second bearing mounting base, the third bearing mounting component, and the first bearing mounting base failing to meet design requirements. This invention uses several locking assemblies to lock and fix the second bearing mounting base and the third bearing mounting component, after angle adjustment, onto the first bearing mounting base. A lightweight outer shell is used to embed and fix the locking end of the locking assembly. This effectively prevents the locking assembly from loosening, thus effectively solving the problem of insufficient connection stability between the second bearing mounting base, the third bearing mounting component, and the first bearing mounting base, significantly improving the practical effect of this invention.
[0015] 3) At least one corresponding weight-reducing hole is provided on the first bearing mounting seat of this utility model. The weight-reducing hole can effectively further reduce the overall weight of this utility model and improve the overall connection between the lightweight shell and the high-strength frame, thereby effectively further improving the structural stability of this utility model.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] refer to Figure 1-4 A lightweight reducer housing, comprising: A set of high-strength frames 1 includes a first bearing mounting seat 101, which is provided with a corresponding first bearing mounting hole 2. A corresponding second bearing mounting seat 102 is installed at an adjustable angle on the rear side of the first bearing mounting seat 101. A corresponding second bearing mounting hole 3 is provided on the second bearing mounting seat 102. A corresponding third bearing mounting component 103 is installed at an adjustable angle on the front side of the first bearing mounting seat 101. A corresponding third bearing mounting hole 4 is provided on the third bearing mounting component 103. Several locking components 5 are used to lock and fix the second bearing mounting base 102 and the third bearing mounting component 103, after the angle adjustment is completed, onto the first bearing mounting base 101 respectively. The lightweight outer shell 6 is disposed around the periphery of a set of high-strength frames 1. The opposite sides of the set of high-strength frames 1 are respectively fixedly embedded in the inner sidewall of the lightweight outer shell 6. The locking ends of the locking components 5 are respectively embedded and fixed inside the lightweight outer shell 6.
[0023] The locking assembly 5 includes a fixing plate 501 fixed to the first bearing mounting seat 101 and a locking plate 502 fixed to the second bearing mounting seat 102 and the third bearing mounting member 103. The fixing plate 501 and the locking plate 502 are respectively provided with a plurality of corresponding connecting holes 7. The relative positions of the fixing plate 501 and the locking plate 502 are adjusted so that the connecting holes 7 on the fixing plate 501 and the locking plate 502 overlap. Then, the corresponding locking bolts 503 are fixedly inserted between the connecting holes 7 of the fixing plate 501 and the locking plate 502, and the locking bolts 503 are fixed and locked by the corresponding locking nuts 504.
[0024] The high-strength frame 1 is made of steel, and the lightweight outer shell 6 is integrally cast from aluminum alloy on the outside of the high-strength frame 1. The joints of the locking nut 504 and the locking bolt 503 are respectively embedded and fixed inside the lightweight outer shell 6.
[0025] The fixing plates 501 are integrally formed in a stepped shape and connected to the first bearing mounting base 101. The locking plates 502 are integrally formed in a stepped shape and connected to the second bearing mounting base 102 and the third bearing mounting component 103. The locking plates 502 are respectively connected to the corresponding fixing plates 501 by an inner and outer overlapping method. Then, the locking bolts 503 and locking nuts 504 are used to fix the locking plates 502 and fixing plates 501 after the docking is completed.
[0026] Several pairs of locking assemblies 5 are used to lock and fix the second bearing mounting base 102 and the third bearing mounting component 103, after angle adjustment, onto the first bearing mounting base 101. Finally, a lightweight outer shell 6 is placed around a set of high-strength frames 1, with the opposite sides of the set of high-strength frames 1 fixedly embedded in the inner wall of the lightweight outer shell 6. The locking end of the locking assembly 5 is then embedded and fixed by the lightweight outer shell 6. In use, the intermediate shaft bearing, input shaft bearing, and output shaft bearing are installed in the corresponding positions of the first bearing mounting base 101, the second bearing mounting base 102, and the third bearing mounting component 103, respectively, and then the various transmission components are installed. By combining a lightweight outer shell 6 with a set of high-strength frames 1, the overall rigidity of the reducer housing is maintained while effectively keeping the weight of the reducer housing at a low level. Moreover, by adjusting the angle between the second bearing mounting base 102, the third bearing mounting component 103 and the first bearing mounting base 101, the installation position of the transmission components can be effectively adjusted, thereby effectively adapting to the installation of transmission components of different specifications and transmission ratios, and greatly improving the adaptability of this utility model.
[0027] While the adjustable angle installation between the second bearing mounting base 102, the third bearing mounting component 103, and the first bearing mounting base 101 can effectively adapt to the installation of transmission components of different specifications and transmission ratios, the locking stability of the locking assembly 5 used for connection and fixation will loosen as the reducer runs for a longer period of time. This will result in the connection stability between the second bearing mounting base 102, the third bearing mounting component 103, and the first bearing mounting base 101 failing to meet design requirements. This invention uses several locking assemblies 5 to lock and fix the second bearing mounting base 102 and the third bearing mounting component 103, after angle adjustment, onto the first bearing mounting base 101. A lightweight outer shell 6 is used to embed and fix the locking end of the locking assembly 5. This effectively prevents the locking assembly 5 from loosening, thus effectively solving the problem of insufficient connection stability between the second bearing mounting base 102, the third bearing mounting component 103, and the first bearing mounting base 101, significantly improving the practical effect of this invention.
[0028] The front end of the lightweight housing 6 is provided with a transmission component assembly hole 601, and the third bearing mounting hole 4 of the third bearing mounting component 103 extends to the outside of the transmission component assembly hole 601 to facilitate the assembly operation of each transmission component of the reducer.
[0029] The lightweight outer shell 6 has a through hole 602 for the main cone shaft to extend through its rear side. A second bearing mounting base 102 of the high-strength frame 1, located away from the through hole 602, is spaced apart from the first bearing mounting base 101. A corresponding pad 8 is fixedly placed at the gap between the second bearing mounting base 102 and the first bearing mounting base 101. The pad 8 has guide holes corresponding to the connection holes 7 of the fixing plate 501 and the locking plate 502. The locking bolt 503 passes through the connection holes 7 of the fixing plate 501 and the locking plate 502, as well as the guide holes of the pad 8, and is then secured by the locking nut 504. The pad 8 effectively connects the spaced-apart second bearing mounting base 102 and the first bearing mounting base 101, accommodating the installation of main cone shafts of different sizes, thereby further improving the adaptability of this invention.
[0030] The first bearing mounting base 101 is provided with at least one corresponding weight reduction hole 9. The weight reduction hole 9 can effectively reduce the overall weight of the present invention and improve the overall connection between the lightweight shell 6 and the high-strength frame 1, thereby effectively improving the structural stability of the present invention.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
