Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a rear-flange motor that facilitates heat dissipation. Background Technology

[0002] A rear-flange motor is a type of electric or hydraulic motor with the mounting flange located at the rear of the housing. Its structural feature is that it achieves compact installation through the rear flange, making it suitable for industrial scenarios with limited space.

[0003] Chinese patent CN211819782U discloses a rear-flange motor suitable for heat dissipation, comprising a rear flange housing, a drive shaft, an oil distribution plate, and a stator and rotor assembly. The rear flange housing is connected to an oil sealing cap, and the drive shaft is housed within the housing. One end of the drive shaft is connected to a cross coupling, and the other end is connected to the stator and rotor assembly. The oil distribution plate is fitted onto the drive shaft and fixedly connected to the stator and rotor assembly. This utility model, a rear-flange embedded hydraulic vane motor, moves the mounting flange of the hydraulic vane motor rearward and replaces the original keyed shaft with a cross coupling, embedding the hydraulic vane motor into the product, significantly reducing the overall structural size of the product.

[0004] The aforementioned motor has the function of reducing space occupation, but the motor will generate a lot of heat during long-term use. If heat dissipation is not carried out in time, it will affect the working efficiency of the motor. At the same time, when the motor flange is connected to the product, the surface of the product may be uneven, causing the motor output shaft to tilt, which will affect the transmission effect of the motor. Therefore, it is necessary to provide a rear flange motor that is easy to dissipate heat. Utility Model Content

[0005] The purpose of this invention is to provide a rear-mounted flange motor that facilitates heat dissipation, thereby solving the problems of poor heat dissipation in existing motors and the compatibility of the motor with the product surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rear-flange motor for easy heat dissipation, comprising a motor and an output shaft, wherein the motor is provided with an adjustment mechanism; the adjustment mechanism comprises a rear flange and a front flange, the rear flange is welded to the motor, and four supports are fixedly installed between the rear flange and the front flange, a threaded tube is threaded through the supports, a torsion seat is fixedly installed at one end of the threaded tube, and a pad is fixedly installed at the other end of the threaded tube.

[0007] Preferably, the four supports are equidistantly installed around the rear flange and the front flange, with the rear flange parallel to the front flange.

[0008] Preferably, an elongated hole is provided through the threaded tube, the torsion seat, and the pad, and the diagonal of the cross section of the torsion seat is smaller than the diameter of the threaded tube.

[0009] Preferably, four circular grooves are provided on one side of the front flange, and the gasket is adapted to the circular grooves.

[0010] Preferably, the output shaft is provided with a heat dissipation mechanism, which includes a mounting base. The mounting base is sleeved on the output shaft, and the mounting base has two mounting slots. Mounting bolts are threaded through the two mounting slots and the output shaft. Several fan blades are fixedly mounted on the mounting base, and several heat dissipation holes are provided on the rear flange.

[0011] Preferably, the output shaft has two through-holes, and the two mounting bolts are perpendicular to each other.

[0012] Preferably, several of the heat dissipation holes protrude from the motor, and gaps are left between adjacent support columns.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) This heat-dissipating rear flange motor connects to the product by inserting a control screw into a threaded tube. If the motor and output shaft tilt, the control torsion seat twists the threaded tube on the support column, causing the pad to move relative to the front flange, thereby achieving relative parallelism between the front flange and the product and achieving the effect of motor angle adjustment. Compared with the traditional shim adjustment method used when installing motors, this method is more practical, flexible and has higher adjustment accuracy.

[0014] 2) This rear-mounted flange motor, which facilitates heat dissipation, benefits from the connection between the mounting bolts, mounting base, mounting groove, and output shaft. When the motor drives the output shaft to rotate, several fan blades will rotate synchronously and allow airflow to enter the heat dissipation hole through the gap between the two pillars. Under the guidance of the heat dissipation hole, the airflow is blown onto the motor surface, achieving a synchronous and efficient heat dissipation effect when the motor is in use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Combination Figures 1-4 A rear-flange motor with easy heat dissipation includes a motor 1 and an output shaft 2. An adjustment mechanism 3 is provided on the motor 1. The adjustment mechanism 3 includes a rear flange 301 and a front flange 302. The rear flange 301 is welded to the motor 1, and four support columns 303 are fixedly installed between the rear flange 301 and the front flange 302. A threaded tube 304 is threaded through the support column 303. A torsion seat 305 is fixedly installed at one end of the threaded tube 304, and a pad 306 is fixedly installed at the other end of the threaded tube 304.

[0019] Four supports 303 are equidistantly installed around the rear flange 301 and front flange 302 to ensure the stability of the motor 1 after installation. The rear flange 301 is parallel to the front flange 302 and has elongated holes through the threaded pipe 304, torque seat 305, and gasket 306. These elongated holes are used to insert screws connecting the motor 1 to the product. During use, screws with a diameter smaller than the diameter of the elongated holes are selected to control the motor 1 to avoid obstructing the adjustment of the threaded pipe 304. The diagonal of the cross-section of the torque seat 305 is smaller than the diameter of the threaded pipe 304 to ensure that the threaded pipe 304 can be installed on the supports 303. Inside 03, four circular grooves are provided on one side of the front flange 302, and the pad 306 is adapted to the circular grooves. In use, the control screw is inserted into the threaded tube 304 and connected to the product. If the motor 1 and the output shaft 2 are tilted, the threaded tube 304 on the support column 303 is twisted by controlling the torsion seat 305, so that the pad 306 moves relative to the front flange 302, thereby achieving the relative parallelism between the front flange 302 and the product, and achieving the effect of adjusting the angle of the motor 1. Compared with the traditional shim adjustment method used when installing the motor 1, this method is more practical, more flexible and has higher adjustment accuracy. Example

[0020] See Figure 5The output shaft 2 is provided with a heat dissipation mechanism 4, which includes a mounting base 401. The mounting base 401 is sleeved on the output shaft 2, and two mounting slots 402 are opened on the mounting base 401. Mounting bolts 403 are threadedly installed through the two mounting slots 402 and the output shaft 2. Several fan blades 404 are fixedly installed on the mounting base 401, and several heat dissipation holes 405 are opened on the rear flange 301.

[0021] Two threaded grooves are formed through the output shaft 2 to fix two mounting bolts 403. The two mounting bolts 403 are perpendicular to each other to ensure the stability of the connection between the mounting base 401 and the output shaft 2. Several heat dissipation holes 405 protrude from the motor 1. There is a gap between adjacent support columns 303. When the motor 1 drives the output shaft 2 to rotate, several fan blades 404 will rotate synchronously and cause airflow to enter the heat dissipation holes 405 through the gap between the two support columns 303. Under the guidance of the heat dissipation holes 405, the airflow is blown onto the surface of the motor 1, achieving a synchronous and efficient heat dissipation effect when the motor 1 is in use.

[0022] In actual operation, by controlling the screw to embed into the threaded tube 304 and connect it to the product, if the motor 1 and the output shaft 2 tilt, by controlling the torsion seat 305 to twist the threaded tube 304 on the support column 303, the pad 306 moves relative to the front flange 302, thereby achieving the relative parallelism between the front flange 302 and the product, achieving the effect of adjusting the angle of the motor 1. Compared with the traditional shim adjustment method used when installing the motor 1, this method is more practical, more flexible and has higher adjustment accuracy. Benefiting from the connection between the mounting bolt 403 and the mounting base 401, the mounting groove 402 and the output shaft 2, when the motor 1 drives the output shaft 2 to rotate, several fan blades 404 will rotate synchronously and allow airflow to enter the heat dissipation hole 405 through the gap between the two support pillars 303. Under the guidance of the heat dissipation hole 405, the airflow is blown onto the surface of the motor 1, achieving a synchronous and efficient heat dissipation effect when the motor 1 is in use.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
