Encoder outlet wire waterproof structure and motor

Technical Field

The application relates to the technical field of motors, in particular to a motor encoder outlet wire waterproof structure and a motor.

Background

An Electric machine (also known as "motor") refers to an electromagnetic device that converts or transmits Electric energy according to the law of electromagnetic induction. The motor is represented by a letter M (old standard is represented by a letter D) in a circuit, the motor mainly plays a role of generating driving torque and serving as a power source of electrical appliances or various machines, and the generator is represented by a letter G in a circuit and mainly plays a role of converting mechanical energy into electric energy. Generally, the motor is a circular device, for example, a gear disc is added to drive a gear system. When the motor works, data monitoring or transmission needs to be carried out on various parameters of the motor, so that the motor usually needs to be externally connected with other equipment, and the connection is generally carried out through a wire. In addition, the motor is generally used in combination with an encoder, which encodes the rotation speed of the motor into high and low level analog signals through a grating, and feeds the signals back to a control system, such as a server, as a signal source, so that the server knows the rotation speed of the motor, and then can control the speed of the motor, or control other links to match the speed of the motor. In other words, the motor is an actuator, the encoder feeds back a signal of the motor to the servo driver, so as to implement a closed-loop control system, and the data of the encoder needs to be conducted through a wire.

However, the motor is required to be waterproof and dustproof during operation, so that the waterproof and dustproof problems caused by the passing of the lead wires need to be solved.

According to some embodiments of the present application, fig. 1 is a schematic structural view of a motor encoder outlet waterproof structure 100 according to some embodiments of the present application, fig. 2 is a schematic view of a motor encoder outlet waterproof structure 100 according to some embodiments of the present application, and fig. 3 is a second view of a motor encoder outlet waterproof structure according to some embodiments of the present application. Referring to fig. 1, 2 and 3, the motor encoder outlet waterproof structure 100 includes a motor end cover 10, an encoder sealing cover 20 and a fastening structure 40 capable of connecting the motor end cover 10 and the encoder sealing cover 20. The motor end cap 10 is provided with an outlet slot 12 for the entry and exit of a motor encoder wire 30.

Fig. 10 is a schematic diagram of an encoder wire 30 according to some embodiments of the present application. The encoder wire 30 has a width d. With continued reference to fig. 1, 2, 3, and 10, the wire 30 is a glue-bound cord. In some possible embodiments, the flexible cord comprises an enameled wire sheathed with a flexible cord sheath. The flexible wire means a multi-strand metal core wire produced by using a multi-strand or single-strand metal wire (generally, a copper wire) as a core and using soft rubber as an insulating sheath. Generally, in order to ensure the softness of the flexible stranded wire, the sectional area of the core of the flexible stranded wire is not too large. The section of the wire outlet groove 12 is smaller than that of the encoder mounting wire, and when the encoder lead 30 penetrates through the wire outlet groove 12 and the fastening structure 40 is fixedly connected with the motor end cover 10 and the encoder 20 sealing cover, the wire outlet groove 12 can be waterproof. This is because the flexible cord glued has the characteristic of being deformed by compression, when the cross-sectional size of the outlet groove 12 is smaller than the cross-sectional size of the encoder wire 30, the encoder wire 30 can be extruded to cause its deformation, and the encoder wire 30 is extruded in the motor casing outlet groove 12 through interference fit, so as to achieve a sealed state and produce an effective sealing waterproof effect.

According to some embodiments of the present application, fig. 4 is a schematic structural view of a motor end cover 10 according to some embodiments of the present application, fig. 5 is a first view of the motor end cover 10 according to some embodiments, and fig. 6 is a second view of the motor end cover 10 according to some embodiments. As shown in fig. 4, the motor end cover 10 has a recess 11 for mounting other devices, a first mounting hole 41 for mounting a fastening device 40, a second mounting hole 42 for fixing an encoder, and a through hole 43, and an outlet groove 12 is formed at a contact portion of the motor end cover 10 and the encoder sealing cover 20. As shown in fig. 4, 5 and 6, the outlet groove 12 has a certain width D. In some embodiments, the width D of the outlet groove 12 is smaller than the diameter D of the encoder wire 30, so that when the encoder wire 30 passes through the outlet groove 12, the encoder wire 30 can be just clamped in the outlet groove 12 by the fastening installation of the fastening device 40, and the outlet groove 12 has no gap due to the deformation of the outer glue of the encoder wire 30, thereby achieving the waterproof and dustproof effects.

According to some embodiments of the present disclosure, a schematic view of an encoder seal cover 20 according to some embodiments of the present disclosure is shown in fig. 7, a first view of an encoder seal cover according to some embodiments of the present disclosure is shown in fig. 8, and a second view of an encoder seal cover according to some embodiments of the present disclosure is shown in fig. 9. Referring to fig. 7, 8 and 9, the encoder sealing cover 20 is substantially circular, and the encoder sealing cover 20 is provided with a mounting hole 21 for mounting the fastening device 40. The encoder sealing cover 20 comprises a convex portion 22, and when the encoder sealing cover 20 is fixed at the motor end cover 10, the convex portion 22 is just covered at the outlet groove 12 to form a mounting hole for the encoder lead 30 to pass through. In other words, when the encoder wire 30 is mounted in the wire outlet groove 12, the encoder sealing cover 20 is fastened to the motor end cover 10 and is fixedly mounted by the fastening structure 40, the protruding portion 22 of the encoder sealing cover 20 and the wire outlet groove 12 can extrude the encoder wire 30 to deform, and thus the dustproof and waterproof effect can be achieved.

The waterproof sealing silica gel glue that needs to add of current outlet or use the sealing rubber piece, and production processes increases, and the cost is increased, and the outlet groove 12 of this application with the setting of encoder wire 30 need not use sealed glue, and the simple cost of process is low.

In some specific embodiments, the fastening device 40 is a fastening screw or a structural member capable of achieving a fixed connection, and is not limited herein.

The outgoing line waterproof structure 100 of the motor encoder has universality and can be used for installation of motors needing water proofing generally. The motor body can be a general motor body, and is not limited in the application.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
