Description

Technical Field

[0001] This utility model relates to a motor end cap, and more particularly to an injection-molded end cap for a dryer motor. Background Technology

[0002] The conventional method for installing a dryer motor involves bolting the end of the motor housing to the bearing end cover, and then connecting the inner side of the bearing end cover to the motor shaft via a bearing. One end of the motor shaft extends through the bearing end cover to the outside of the motor and connects to the dryer frame via a bearing connector. This combination of the bearing connector and the motor shaft supports the end of the dryer motor, ensuring its stable installation within the dryer frame.

[0003] However, the aforementioned connection structure has several drawbacks. Firstly, it is relatively complex, requiring two connecting bearings for installation. Furthermore, operators must separately fit and press the bearing end caps and bearing connectors together, increasing the production cost and assembly difficulty of the dryer motor. Secondly, because the bearing connector is directly fitted onto the outside of the motor shaft, it is prone to axial movement relative to the motor shaft during operation, failing to provide axial restraint for the dryer motor.

[0004] Therefore, the existing installation methods for dryer motors suffer from problems such as complex structure and poor limiting effect. Utility Model Content

[0005] The purpose of this invention is to provide an injection-molded end cap for a dryer motor. It simplifies the installation structure of the dryer motor, thereby improving the ease of assembly and installation stability.

[0006] The technical solution of this utility model: an injection-molded end cap for a dryer motor, including a bearing cap, the bearing cap being covered with a plastic coating layer, one end of the plastic coating layer forming an insertion part, an installation frame being fitted on the outside of the insertion part, and a rubber ring being fastened to the outside of the installation frame; several outwardly protruding pressing parts are distributed around the insertion part, and the inner wall of the installation frame and the pressing parts are fitted together to form an interference fit.

[0007] In the aforementioned injection-molded end cap for a dryer motor, one end of the bearing cap forms a first bend extending radially outward, and the other end of the bearing cap forms a second bend extending radially inward. A Z-shaped covering surface is formed between the first bend, the bearing cap, and the second bend, and the inner end of the plastic coating layer is completely fitted with the covering surface.

[0008] In the aforementioned injection-molded end cap for a dryer motor, the bearing cap extends to the outside of the plastic coating layer at one end near the second bend and forms a bushing for connecting the motor shaft.

[0009] In the aforementioned injection-molded end cap for a dryer motor, the middle part of the second bend forms an outwardly protruding step, and the end of the plastic coating completely covers the step.

[0010] In the aforementioned injection-molded end cap for a dryer motor, the plastic coating layer has several mounting feet distributed around its perimeter for bolting the motor housing.

[0011] In the aforementioned injection-molded end cap for a dryer motor, the plastic coating layer has a positioning ring on the side near the mounting foot for fastening and connecting to the motor housing, and a locking block on one side of the positioning ring for fastening and connecting to the motor housing. The positioning ring is used to radially limit the plastic coating layer relative to the motor housing, and the locking block is used to circumferentially limit the plastic coating layer relative to the motor housing.

[0012] In the aforementioned injection-molded end cap for a dryer motor, the pressing part is elongated and completely covers the outer wall of the insertion part along the axial direction of the insertion part.

[0013] In the aforementioned injection-molded end cap for a dryer motor, the outer wall of the mounting frame forms an annular mounting groove, the rubber ring is fastened and connected in the mounting groove, and the outer ring of the rubber ring extends to the outside of the mounting groove and is used to connect the dryer frame.

[0014] Compared with the prior art, this utility model has the following characteristics: (1) By limiting the structure of the injection molded end cap, this utility model can combine the original bearing end cap and bearing connector, so that the inner side of the bearing cap can be connected to the motor shaft through the bearing, and the outer side of the bearing cap can extend to the outer side of the end of the dryer motor and be connected to the dryer frame through the rubber ring. Thus, while realizing the function of fixing the dryer motor, the bearing connector between the motor shaft and the dryer frame is eliminated, reducing the production cost of the dryer motor. (2) By fastening the mounting frame to the pressing part and forming an interference fit, and fastening the rubber ring to the outside of the mounting frame, the rubber ring can be axially fixed relative to the dryer motor after installation, so that the outer ring of the rubber ring can limit the dryer motor by friction after it is attached to the dryer frame, thereby improving the installation stability of the dryer motor in the dryer frame. (3) By limiting the structure of the clamping part, the fixing effect of the mounting frame after insertion can be improved and the possibility of the mounting frame being disengaged can be reduced; by limiting the shape and connection structure of the bearing cover and the plastic coating layer, the connection stability between the plastic coating layer and the bearing cover can be improved on the one hand, and the overall structural strength of the injection molded end cap can be improved on the other hand. Therefore, this utility model simplifies the installation structure of the dryer motor, thereby improving the assembly convenience and installation stability of the dryer motor.

[0016] The markings in the attached diagram are as follows: 1-bearing cap, 2-plastic coating layer, 3-insertion part, 4-mounting frame, 5-rubber ring, 6-pressing part, 101-first bend, 102-second bend, 103-shaft sleeve, 104-step part, 201-mounting foot, 202-positioning ring, 203-block, 401-mounting groove. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example. A molded end cap for a dryer motor, configured as follows: Figure 1 As shown, the bearing includes a bearing cover 1, the bearing cover 1 is covered with a plastic coating layer 2, one end of the plastic coating layer 2 forms a plug-in part 3, a plastic mounting frame 4 is sleeved on the outside of the plug-in part 3, and a rubber ring 5 is fastened to the outside of the mounting frame 4; several outwardly protruding pressing parts 6 are distributed around the plug-in part 3, and the inner wall of the mounting frame 4 and the pressing parts 6 are fitted together to form an interference fit.

[0019] One end of the bearing cover 1 forms a first bend 101 extending radially outward, and the other end of the bearing cover 1 forms a second bend 102 extending radially inward. A Z-shaped covering surface is formed between the first bend 101, the bearing cover 1, and the second bend 102. The inner end of the plastic coating layer 2 is completely attached to the covering surface. The structural cooperation between the covering surface and the plastic coating layer 2 can improve the connection stability and structural strength between the plastic coating layer 2 and the bearing cover 1, and reduce the possibility of the bearing cover 1 deforming and falling off.

[0020] The bearing cap 1 extends to the outside of the plastic coating layer 2 at one end near the second bend 102 and forms a bushing 103 for connecting the motor shaft.

[0021] The second bending portion 102 forms an outwardly protruding step portion 104 in the middle. The end of the plastic coating layer 2 completely covers the step portion 104. The step portion 104 can further improve the deformation resistance of the bearing cover 1 and the connection stability between the plastic coating layer 2 and the bearing cover 1.

[0022] The plastic coating layer 2 has several mounting feet 201 distributed around its perimeter for bolting the motor housing.

[0023] The plastic coating layer 2 has a positioning ring 202 for fastening and connecting the motor housing on the side near the mounting foot 201. A locking block 203 for fastening and connecting the motor housing is provided on one side of the positioning ring 202. The positioning ring 202 is used to radially limit the plastic coating layer 2 relative to the motor housing, and the locking block 203 is used to circumferentially limit the plastic coating layer 2 relative to the motor housing.

[0024] The clamping part 6 is elongated and completely covers the outer wall of the insertion part 3 along the axial direction of the insertion part 3. After the mounting frame 4 is inserted, a local deformation is formed at the connection of the clamping part 6, thereby relying on the deformation of the mounting frame 4 to completely clamp the insertion part 3, reducing the possibility of the mounting frame 4 falling off later.

[0025] The outer wall of the mounting frame 4 forms an annular mounting groove 401. The rubber ring 5 is fastened and connected in the mounting groove 401. The outer ring of the rubber ring 5 extends to the outside of the mounting groove 401 and is used to connect the dryer rack. The cooperation between the mounting groove 401 and the clamping part 6 enables the rubber ring 5 to form an axial limit relative to the plastic coating layer 2 after installation, preventing the possibility of the rubber ring 5 falling off or moving axially during subsequent use.

[0026] The working principle of this utility model is as follows: This utility model combines the original bearing end cover used for rotatably connecting the motor shaft and the bearing connector used for connecting the dryer frame. After installation, the injection-molded end cover can connect to the motor shaft via the bearing cover 1, and connect to the dryer frame through the cooperation of the mounting frame 4 and the rubber ring 5, thereby achieving the connection and fixation of the dryer motor within the dryer frame. Based on this, manufacturers can install the injection-molded end cover in one go during assembly, thus improving the assembly efficiency of the dryer motor.
