Description

Technical Field

[0001] This utility model relates to a speed reducer, and more particularly to a compact speed reducer with double-sided output. Background Technology

[0002] In the application of horizontal shaft tunneling machines (TBMs), power transmission is a crucial link in ensuring the efficient operation of the equipment. Currently, TBMs mainly use gear transmission to transmit power to the various cutting drums on the horizontal shaft. However, this transmission method has certain drawbacks. Because the gears are housed inside a gearbox, and the gearbox itself has a certain thickness, a relatively large blind spot is inevitably created. The existence of this blind spot affects the comprehensiveness and accuracy of the tunneling operation, requiring the use of lateral moving equipment to eliminate this blind spot, which to some extent reduces operational efficiency and increases operational complexity.

[0003] like Figure 1 and Figure 2 The figures show the application of two-wheeled and six-wheeled square drills in relevant operational scenarios. In the field of square pile excavation, the existing power transmission schemes differ from those of horizontal shaft tunneling machines. This field typically does not employ the integrated reduction gear transmission structure described above; instead, two reducers are arranged on each side of the partition, meaning each drum requires a corresponding reducer. Two-wheeled square drills require two reducers, and six-wheeled square drills require six reducers. While this decentralized arrangement meets the power transmission requirements to some extent, it also introduces a series of new problems.

[0004] On the one hand, with the increase in the number of reducers, the number of matching motors also increases accordingly. In terms of oil supply, it is difficult to achieve precise and even oil supply to each motor. This leads to some motors malfunctioning due to insufficient or excessive oil, making them prone to damage, shortening the equipment's lifespan, and increasing maintenance costs. On the other hand, with multiple motors working simultaneously, it is difficult to achieve ideal synergy in the distribution of driving force, easily resulting in insufficient driving force. This fails to meet the high power requirements during square pile excavation, affecting the project's progress and quality.

[0005] In view of the above-mentioned problems in the existing technology, in order to optimize the power transmission structure, improve the stability and efficiency of equipment operation, and reduce maintenance costs, a compact reducer with double-sided output is proposed to overcome the shortcomings of the existing technology. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a compact speed reducer with double-sided output to overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A compact speed reducer with dual-sided output includes a speed reducer and a rotating shaft. A first output mechanism is drivenly connected to the output end of the speed reducer, and the first output mechanism is drivenly connected to one end of the rotating shaft through a first transmission mechanism.

[0009] One end of the rotating shaft is provided with a second transmission mechanism, and a second output mechanism is connected to it through the second transmission mechanism. The first output mechanism and the second output mechanism are respectively arranged on both sides of the reducer to realize the double-sided output of the reducer.

[0010] Furthermore, it also includes a drive assembly mounted at the input end of the reducer to provide power to the reducer.

[0011] Furthermore, it also includes a housing for mounting the speed reducer.

[0012] Furthermore, the rotating shaft is rotatably mounted in the housing, and both ends of the rotating shaft are located on both sides of the housing.

[0013] Furthermore, the first output mechanism is a first output shaft that is rotatably connected to the housing.

[0014] Furthermore, the second output mechanism is a second output shaft that is rotatably connected to the housing.

[0015] Furthermore, the reducer, the first output mechanism, and the second output mechanism are arranged coaxially.

[0016] Furthermore, the rotating shaft is arranged on the outer circumference of the reducer and parallel to the axis of the reducer.

[0017] Furthermore, the first transmission mechanism is one of a gear transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism.

[0018] Furthermore, the second transmission mechanism is one of a gear transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model proposes a compact double-sided output reducer, the core of which lies in achieving dual-sided power output using a single drive component and reducer. The output end of the reducer is connected to the first output mechanism (output 1), and the power is transmitted to the rotating shaft on the housing through the first transmission mechanism. The rotating shaft is then connected to the second output mechanism (output 2) through the second transmission mechanism. The rotating shaft acts as a key bridge for power transmission, enabling efficient distribution of power from the input end to both output ends, successfully achieving the function of double-sided output. This design is not only ingenious in structure but also lays the foundation for compactness and high efficiency.

[0021] 2. This utility model achieves double-sided output with a single drive component, reducing the number of drive parts, making the structure more compact, and lowering manufacturing and maintenance costs. Secondly, the transmission mechanism (such as gear or chain drive) ensures efficient and reliable power transmission while providing flexible spatial layout options. Furthermore, the coaxial or parallel arrangement of the reducer, output mechanism, and rotating shaft optimizes space utilization and improves system stability and overall performance. These advantages collectively enhance the practical value and economy of the reducer.

[0022] 3. Compared to traditional speed reducers, conventional designs requiring dual-sided output (such as a two-wheeled square drill) typically rely on two independent drive components and speed reducers, resulting in a complex system, high cost, and large space occupation. This technology, however, uses only one drive system, achieving dual-sided output through an innovative power transmission structure, significantly improving integration and economy. The choice of transmission mechanism also gives users the ability to flexibly configure according to actual needs, making it more adaptable and competitive in various application scenarios. This innovative design undoubtedly brings a new technological breakthrough to the speed reducer field.

[0032] Example 1

[0033] like Figure 3 As shown, a compact speed reducer with dual-sided output includes a housing 1, a drive assembly 2, a speed reducer 3, a first output mechanism 4, a rotating shaft 5, a first transmission mechanism 6, a second transmission mechanism 7, and a second output mechanism 8.

[0034] The drive assembly 2 is installed at the input end of the reducer 3 and is used to provide power to the reducer 3. For example, it can be a hydraulic motor or an electric motor. The reducer 3 is mounted on the housing 1, and its output end is drivenly connected to the first output mechanism 4. The first output mechanism 4 is a first output shaft that is rotatably connected to the housing 1 through bearings and is used to output the power of the reducer 3.

[0035] In another embodiment, the first output mechanism 4 can also be directly set as the output end body of the reducer 3, that is, a part of the reducer body (such as the output end housing).

[0036] The rotating shaft 5 is rotatably mounted in the housing 1 via bearings, with its two ends located on opposite sides of the housing 1 to transmit power from one side to the other. One end of the rotating shaft 5 is connected to the first output mechanism 4 via a first transmission mechanism 6. The first transmission mechanism 6 is a gear transmission mechanism, specifically including a first gear fixedly mounted on the first output mechanism 4 and a second gear fixedly mounted on one end of the rotating shaft 5. The first gear and the second gear mesh directly, thereby transmitting the rotational power of the first output mechanism 4 to the rotating shaft 5.

[0037] The other end of the rotating shaft 5 is provided with a second transmission mechanism 7, which is also a gear transmission mechanism, including a third gear fixedly installed at the other end of the rotating shaft 5 and a fourth gear fixedly installed on the second output mechanism 8. The third gear and the fourth gear mesh directly. The second output mechanism 8 is a second output shaft that is rotatably connected to the housing 1 through bearings, and is used to receive power from the rotating shaft 5 and output it.

[0038] Specifically, in this embodiment, the rotating shaft 5 can be configured as an idler shaft. In this embodiment, the reducer 3, the first output mechanism 4, and the second output mechanism 8 are arranged coaxially to ensure efficient power transmission and a compact structure. The rotating shaft 5 is arranged on the outer circumference of the reducer 3 and parallel to the axis of the reducer 3 to make full use of space and achieve double-sided output.

[0039] During operation, drive assembly 2 drives reducer 3 to rotate, and the output end of reducer 3 drives the first output mechanism 4 (i.e., the first output shaft) to rotate. The first output mechanism 4 transmits power to rotating shaft 5 through the first transmission mechanism 6 (gear transmission), causing rotating shaft 5 to rotate synchronously. Rotating shaft 5 then transmits power to second output mechanism 8 (i.e., the second output shaft) through the second transmission mechanism 7 (gear transmission). Thus, the power of reducer 3 is output from the input end and the output end respectively through the first output mechanism 4 and the second output mechanism 8, realizing the function of double-sided output.

[0040] Furthermore, the first output mechanism 4 and the second output mechanism 8 can extend along their length to output multiple power sources; or a set of gear transmission mechanisms can be arranged on the first output shaft to directly drive the load arranged outside the first output mechanism 4.

[0041] The advantage of this design is that it can achieve dual-sided power output through a single drive component 2 and reducer 3, specifically power output on both sides of the housing, which reduces the number of drive components, makes the overall structure more compact, and reduces manufacturing and maintenance costs.

[0042] Example 2

[0043] A compact speed reducer with dual-output includes a housing 1, a drive assembly 2, a speed reducer 3, a first output mechanism 4, a rotating shaft 5, a first transmission mechanism 6, a second transmission mechanism 7, and a second output mechanism 8.

[0044] The drive assembly 2 is installed at the input end of the reducer 3 and is used to provide power to the reducer 3. For example, it can be a hydraulic motor or a servo motor. The reducer 3 is mounted on the housing 1, and its output end is drivenly connected to the first output mechanism 4. The first output mechanism 4 is a first output shaft that is rotatably connected to the housing 1 through bearings and is used to output the power of the reducer 3.

[0045] The rotating shaft 5 is rotatably mounted in the housing 1 via bearings, with its two ends located on opposite sides of the housing 1 to transmit power. One end of the rotating shaft 5 is connected to the first output mechanism 4 via the first transmission mechanism 6.

[0046] The difference between this embodiment and embodiment 1 is that the first transmission mechanism 6 is a chain transmission mechanism, specifically including a first sprocket fixedly installed on the first output mechanism 4, a second sprocket fixedly installed on one end of the rotating shaft 5, and a chain connecting the first sprocket and the second sprocket, through which the rotational power of the first output mechanism 4 is transmitted to the rotating shaft 5.

[0047] The other end of the rotating shaft 5 is provided with a second transmission mechanism 7, which is also a chain drive mechanism. It includes a third sprocket fixedly installed at the other end of the rotating shaft 5, a fourth sprocket fixedly installed on the second output mechanism 8, and a chain connecting the third sprocket and the fourth sprocket. The second output mechanism 8 is a second output shaft that is rotatably connected to the housing 1 through bearings, and is used to receive power from the rotating shaft 5 and output it.

[0048] In this embodiment, the reducer 3, the first output mechanism 4, and the second output mechanism 8 are arranged coaxially to optimize power transmission efficiency and structural compactness. The rotating shaft 5 is arranged on the outer circumference of the reducer 3 and parallel to the axis of the reducer 3 to accommodate the space requirements of the chain drive.

[0049] During operation, drive assembly 2 drives reducer 3 to rotate, and the output end of reducer 3 drives the first output mechanism 4 (i.e., the first output shaft) to rotate. The first output mechanism 4 transmits power to the rotating shaft 5 through the first transmission mechanism 6 (chain drive), causing the rotating shaft 5 to rotate synchronously. The rotating shaft 5 then transmits power to the second output mechanism 8 (i.e., the second output shaft) through the second transmission mechanism 7 (chain drive). Thus, the power of reducer 3 is output from the input end and the output end respectively through the first output mechanism 4 and the second output mechanism 8, realizing the function of double-sided output.

[0050] Compared to Example 1, this example uses chain drive, which can accommodate larger center distances and more flexible spatial layouts, making it suitable for applications requiring a larger transmission ratio or where space is limited. Furthermore, chain drive provides cushioning and shock absorption, contributing to improved system stability and lifespan.

[0051] In another embodiment, the chain drive mechanism may be replaced by a belt drive mechanism.

[0052] Specifically, the compact speed reducer with double-sided output in Embodiments 1 and 2 above can be applied to, for example... Figure 1 In the two-wheel square drill shown, the two drive components (motors) and two reducers in the prior art can be replaced by a compact reducer with double-sided output as described in this application, along with a drive component. Specifically, the drive component 2 in the embodiment is replaced by a motor, which is then mounted on the support housing of the two-wheel square drill (housing 1 in the embodiment is replaced by a support housing). The first output mechanism 4 and the second output mechanism 8 in the embodiment are then connected to the rollers on both sides, and the rollers on both sides are driven by a single motor. This reduces the arrangement of drive components and reducers, optimizes the power transmission structure, and reduces the blind zone between the two drill bits, thereby ensuring better driving and cutting effects for the two-wheel square drill.

[0053] Alternatively, the compact speed reducer with double-sided output described in Embodiments 1 and 2 above can be applied to, for example... Figure 2 In the six-wheel squaring drill shown, the four drive components (motors) and four reducers arranged in groups on both sides in the prior art can be replaced by two sets of compact reducers and drive components with double-sided output as described in this application. The specific replacement method can be referred to as the two-wheel squaring drill, which drives four rollers arranged on both sides through two motors, thereby reducing the arrangement of drive components and reducers, optimizing the power transmission structure, solving the problem of oil source distribution, and reducing the blind zone between the two drill bits. As a result, the independent rollers between the blind zones of the partition can be eliminated, forming a four-wheel squaring drill with no blind zone or a very small blind zone, thereby ensuring better driving and cutting effects of the squaring drill.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
