Description

Technical Field

[0001] The utility model relates to a motor, and in particular to a motor housing casting with vibration damping and load-bearing functions. Background Art

[0002] At present, the Chinese patent with the publication number CN219041527U discloses a motor housing, including a main body that forms a cylindrical cavity for accommodating a motor rotor, and a fan blade housing with an open end and a closed end. A circle of heat dissipation fins is arranged on the outside of the main body.

[0003] The above patent still has deficiencies. Motors are usually used as power sources. However, in the design of some non-standard production lines, to increase space utilization or improve connection strength, it is necessary to use the motor as both a support part and a power source at the same time. There is a circle of heat dissipation fins on the outside of the motor main body of the above patent, which cannot support the load, and at the same time, the structural strength of the main body is relatively low and it is easy to deform when receiving pressure. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a motor housing casting with vibration damping and load-bearing functions, which has a load-bearing function.

[0005] To solve the above technical problems, the technical solution of the utility model is: A motor housing casting with vibration damping and load-bearing functions, including a housing, a front end cover and a rear end cover. The front end cover and the rear end cover are respectively fixed on the front and rear sides of the housing. A cavity for placing a rotor and a stator is opened inside the housing. The cross-section of the housing is in a drum shape. Heat dissipation fins are arranged on both the left and right sides and the lower side of the housing. Support feet are arranged at the lower end of the housing. A first rib plate is also arranged between the support feet and the heat dissipation fins. The housing, the heat dissipation fins, the gusset plate and the support feet are all integrally cast. A plurality of second rib plates are also arranged between the two heat dissipation fins, and the second rib plates and the heat dissipation fins are integrally formed.

[0006] By the above technical means, by setting the housing in a drum shape, the parts at the upper end of the housing can be placed stably on the housing. By arranging the second rib plates on the heat dissipation fins, the structural strength of the side end of the housing is increased, thereby increasing the load-bearing capacity of the housing. By integrally casting the housing, the heat dissipation fins, the second rib plates, the gusset plate and the support feet, the structural strength is further increased.

[0007] Preferably, heat dissipation fins are also arranged at the upper end of the housing, and a gusset plate is also arranged at the upper end of the housing. The gusset plate is staggered with the heat dissipation fins, and threaded holes are opened on the gusset plate.

[0008] By means of the above technical means, by providing gusset plates at the upper end of the casing, it is convenient to connect the casing with the upper parts. At the same time, the connection plane is raised by the gusset plates, so that heat dissipation fins can be provided at the upper end of the casing, increasing the heat dissipation efficiency.

[0009] Preferably, a third rib plate is further provided between the gusset plate and the casing. The third rib plate is fixed to the bottom side of the gusset plate by welding, and the third rib plate is arranged offset from the threaded hole.

[0010] By means of the above technical means, by welding the third rib plate to the bottom side of the gusset plate, the connection between the gusset plate and the casing is made more stable.

[0011] Preferably, a connection hole is further opened on the bottom surface of the support foot, and a shock-absorbing backing plate is provided on the bottom side of the support foot. The shock-absorbing backing plate includes a rubber plate and a bottom plate, and the rubber plate is arranged between the support foot and the bottom plate.

[0012] By means of the above technical means, by providing a rubber plate and a bottom plate at the bottom of the support foot, the influence of vibration on the connection part is reduced, and the generation of noise is reduced.

[0013] Preferably, a first vertical mounting plate is further provided at the tail of the bottom plate, a second vertical mounting plate is provided on the rear end cover, and waist-shaped holes are opened on both the first vertical mounting plate and the second vertical mounting plate.

[0014] By means of the above technical means, by providing a first vertical mounting plate at the tail and a second vertical mounting plate on the rear end cover, the motor can be vertically mounted, increasing the mounting methods to make the motor adapt to more mounting scenarios and increasing the applicability.

[0015] Preferably, a plurality of T-shaped grooves are further provided on the front end of the casing. A sliding lock block is arranged in the T-shaped groove, a patch plate is further provided outside the T-shaped groove, the patch plate and the sliding lock block are fixed by screws, and a top plate is further provided outside the front end cover. The top plate and the sliding lock block are fixed by screws.

[0016] By means of the above technical means, through the cooperation between the sliding lock block and the patch plate and being fixed by screws, the sliding lock block can be fixed at any position in the T-shaped groove. Through the fixation between the top plate and the sliding lock block, it is convenient for the top plate to resist the upper parts of the motor when the motor is vertically mounted, thereby further increasing the applicability of the motor.

[0017] Preferably, the casing is formed by casting with high-damping cast iron.

[0018] By means of the above technical means, by manufacturing the casing with high-damping cast iron, the vibration reduction and noise reduction capabilities of the motor are improved, and at the same time, the fatigue life of the motor is improved. Description of the Drawings
