Description

Technical Field

[0001] This utility model relates to the field of drive structure, and in particular to a direct connection structure between an electric motor and a gearbox. Background Technology

[0002] In industrial transmission systems, electric motors and gearboxes need to transmit power to achieve operation. Traditional solutions often rely on intermediate components such as couplings and transition flanges for connection. In addition, in traditional structures, clutches are often external or require additional brackets for fixation, which not only takes up more space but also increases assembly complexity. During later maintenance, multiple intermediate components need to be disassembled, making the operation cumbersome. At the same time, traditional connection structures lack a closed protective design, and the connection between the electric motor and gearbox is susceptible to dust and moisture intrusion, leading to corrosion and wear of internal components and shortening the life of the transmission system.

The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0017] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 As shown, a direct connection structure between an electric motor and a gearbox includes an electric motor 1, a clutch 2, and a gearbox 3; the electric motor 1, clutch 2, and gearbox 3 are sequentially connected and fixed; the output end of the electric motor 1 is connected to a fixing sleeve 4, and the fixing sleeve 4 is uniformly provided with multiple sets of fixing sleeve blind holes 401 in a ring around its periphery. The fixing sleeve blind holes 401 are fixedly connected to a flywheel disc 5 by bolts. The flywheel disc 5 is provided with multiple sets of flywheel disc blind holes 501 around its periphery, and the clutch 2 is fixedly connected to the flywheel disc blind holes 501 by bolts; the clutch 2 is provided with a clutch fixing hole 201 at its center, and the input shaft of the gearbox 3 is inserted into the clutch fixing hole 201 for docking and limiting.

[0019] like Figure 1 As shown, a fixing ring 101 is provided on the outer end face of the output end of the motor 1. The fixing ring 101 is connected to the intermediate sleeve 6. The other end of the intermediate sleeve 6 is connected to the outer end face of the gearbox 3 by bolts. The main body of the clutch 2 is placed inside the intermediate sleeve 6. The motor and the reducer are connected through the intermediate sleeve, which can protect the connection between the two and improve the dustproof and waterproof effect.

[0020] like Figure 1 As shown, the fixing sleeve 4 is a cylindrical structure with one end open. The fixing sleeve 4 has a through hole 402 in the center. The fixing sleeve 402 is fixedly connected to the end face of the motor output end by an embedded bolt. In order to avoid relative rotation between the fixing sleeve and the motor output end, the two can also be designed as spline groove docking to ensure stability.

[0021] like Figure 1 As shown, after the motor 1 is connected to the gearbox through the intermediate sleeve 6, the input end of the clutch 2 is located in the clutch fixing hole 201. The clutch fixing hole 201 and the input end of the clutch 2 are connected by a spline groove, which facilitates docking and subsequent maintenance.

[0022] like Figure 1 As shown, wear-resistant gaskets are provided between the motor 1 and the intermediate sleeve 6, between the intermediate sleeve 6 and the gearbox, and between the fixed cylinder 4 and the output end of the motor 1. Wear-resistant gaskets can prevent hard contact between metals and provide a seal for the connection, preventing dust and water seepage.

[0023] The working principle of this utility model is explained as follows: After the motor starts, the power is transmitted to the fixed sleeve through the output end. The fixed sleeve is bolted to the flywheel, causing the flywheel to rotate synchronously. The flywheel then transmits the power to the clutch fixed thereto. When the clutch is engaged, the power is transmitted to the input shaft of the gearbox through the clutch fixing hole in the center of the clutch (through spline groove engagement), realizing the direct transmission of power from the motor to the gearbox, completing the deceleration and torque increase or speed change function. The intermediate sleeve is connected to the motor through the fixing ring and fixed to the end face of the gearbox, enclosing the clutch and forming a closed protective space. The wear-resistant gaskets at each connection point reduce metal friction loss and enhance sealing performance, preventing dust and moisture from entering and affecting transmission efficiency.
