Description

Technical Field

[0001] This utility model relates to the technical field of speed reducers, and in particular to a dual-shaft feeding speed reducer for lithium batteries. Background Technology

[0002] See Figure 1 Currently, commercially available dual-shaft feed reducers for lithium batteries generally include a drive motor (a), four series gearboxes (b), a distribution box (c), and a connecting flange (d). The four series gearboxes (b) can be one of the following: R-series helical gears, F-series parallel shaft helical gears, K-series spiral bevel gears, or S-series helical gears. The distribution box (c) is connected in series with the four series gearboxes (b) via a coupling. This type of reducer has a relatively long axial structural dimension, which easily leads to a large overall length and high space occupancy. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a dual-shaft feeding reducer for lithium batteries, which has a more compact structure, shorter axial dimension, saves installation space, and is also more cost-effective.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dual-shaft feeding reducer for lithium batteries, including a drive motor, a connecting flange, and an integrated housing. The connecting flange is installed and fixed on one side of the integrated housing. The interior of the integrated housing has a motor pinion, an intermediate gear shaft, a first output gear shaft, a second output gear shaft, bearings, a pressure plate, and a large gear. The motor pinion is installed and fixed on the motor shaft of the drive motor. The intermediate gear shaft, the first output gear shaft, and the second output gear shaft are installed parallel to each other on the connecting flange. The intermediate gear shaft meshes with the first output gear shaft and the second output gear shaft respectively. The large gear is installed at the end of the intermediate gear shaft and meshes with the motor pinion.

[0005] To be further specific, in the above technical solution, the drive motor and the motor pinion are interference-fitted.

[0006] To be further specific, in the above technical solution, bearings are installed at the tail ends of both the first output gear shaft and the second output gear shaft, and pressure plates are installed at the tail ends of the bearings.

[0007] To be further specific, in the above technical solution, the bearing is a pair of single-row tapered roller bearings, which are installed back-to-back.

[0008] To be further specific, in the above technical solution, the intermediate gear shaft, the first output gear shaft, and the second output gear shaft are arranged in a triangular pattern.

[0009] The beneficial effects of this utility model are: the dual-shaft feeding reducer for lithium batteries has a distribution box and a main transmission box designed as an integrated structure, and the motor pinion is directly fixed on the motor shaft of the drive motor, eliminating the need for a motor coupling. This results in a more compact structure, a shorter axial dimension, saving installation space, and lower cost. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model discloses a dual-shaft feeding reducer for lithium batteries, comprising a drive motor 1, a connecting flange 7, and an integrated housing 3. The connecting flange 7 is fixedly mounted on one side of the integrated housing 3. The integrated housing 3 contains a motor pinion 2, an intermediate gear shaft 4, a first output gear shaft 5, a second output gear shaft 6, a bearing 8, a pressure plate 9, and a large gear 10. The motor pinion 2 is fixedly mounted on the motor shaft of the drive motor 1. The intermediate gear shaft 4, the first output gear shaft 5, and the second output gear shaft 6 are mounted parallel to each other on the connecting flange 7. The intermediate gear shaft 4 meshes with the first output gear shaft 5 and the second output gear shaft 6 respectively. The large gear 10 is mounted on the end of the intermediate gear shaft 4 and meshes with the motor pinion 2.

[0021] The drive motor 1 and the pinion 2 are interference-fitted, a design that provides advantages such as high-efficiency transmission, compact structure, and impact resistance. Bearings 8 are mounted at the tails of both the first output gear shaft 5 and the second output gear shaft 6. Preferably, the bearings 8 are paired single-row tapered roller bearings, installed back-to-back to withstand bidirectional axial forces. A pressure plate 9 is mounted at the tail of each bearing 8, used to adjust the installation clearance of the bearing 8 and to withstand the axial force. The intermediate gear shaft 4, the first output gear shaft 5, and the second output gear shaft 6 are arranged in a triangular configuration. These three components are the core transmission parts of the reducer, responsible for power transmission, torque amplification, and load support. They achieve speed reduction and torque increase through gear meshing.

[0022] Specifically, this invention directly drives the motor pinion 2 via a drive motor 1, and the drive motor 1 and the motor pinion 2 are connected by a special tapered bore interference fit. The motor pinion 2 transmits 100% of the motor power to the intermediate gear shaft 4, which in turn drives the first output gear shaft 5 and the second output gear shaft 6. The first output gear shaft 5 and the second output gear shaft 6 each transmit 50% of the power to the customer spindle. To ensure that the first output gear shaft 5 and the second output gear shaft 6 are in phase, the gears and output splines on the first output gear shaft 5 and the second output gear shaft 6 adopt a differential tooth design.

[0023] The working principle of this dual-shaft feeding reducer for lithium batteries is as follows: the drive motor 1 directly drives the motor pinion 2, which meshes with the large gear 10 to drive the intermediate gear shaft 4; the intermediate gear shaft 4 simultaneously meshes with the first output gear shaft 5 and the second output gear shaft 6, transmitting power to the first output gear shaft 5 and the second output gear shaft 6 respectively, with each of the first output gear shaft 5 and the second output gear shaft 6 transmitting 50% of the torque; the connecting flange 7 and the integrated housing 3 are connected by bolts, and the connecting flange 7 is used to connect the client cylinder.

[0024] The present invention relates to a dual-shaft feeding reducer for lithium batteries, in which the distribution box and the main transmission box are designed as an integrated structure, making the structure more compact. The motor is directly driven, eliminating the need for a coupling. That is, the motor pinion 2 is directly fixed on the motor shaft of the drive motor 1, eliminating the need for a motor coupling. The overall axial dimension is shorter, saving equipment installation space and reducing costs.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
