Abstract
The utility model discloses a motor sealing structure including sealing rubber arranged on a rear cover of a motor. A pure-nylon waterproof joint and a waterproof shell are arranged on the rear cover of the motor at positions corresponding to a power cable. A waterproof quick joint is arranged outside the rear cover of the motor at an outlet of the power cable. By adopting the dual waterproof structure for sealing and resisting water, so that gaps in the inner part of the motor sealing structure are eliminated and the good sealing effect is guaranteed. And a power cable adaption process is avoided, so that risks caused by vibration are avoided and the working reliability of the motor is improved.
Description
Technical field
The utility model relates to technical field of motors, especially relates to a kind of motor sealing structure.
Background technology
At present, the power cable joint of the motor part caulking gums that adopt carry out single sealing more, the inner terminal block switching power cable that adopts, and power cable is drawn from the indentation, there of rear end cap.
As shown in Figure 2, there is following problem in existing motor sealing structure: flat caulking gum 1 structure, and strict to Work piece sealing place requirement on machining accuracy, thus the increase expense; The assembling process difficulty is large, careless slightlyly will cause drainage, and water will flow into motors from breach 8, cause burn-down of electric motor; Motor lead-out wire is in the switching of terminal block 6 places, and great majority are that bolt 7 connects herein, are in the motor of the motor, particularly long-term vibration of adverse circumstances, the danger that can exist bolt to get loose.
The utility model content
Technical problem to be solved in the utility model provides a kind of motor sealing structure, to reach good sealing effectiveness, improves the purpose of the reliability of machine operation.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of motor sealing structure, comprise the caulking gum on the motor rear cover, and corresponding power cable place is provided with full nylon water joint and waterproof case on motor rear cover.
The outside of described motor rear cover is provided with the waterproof fast joint at the power cable place of drawing.
The utility model compared with prior art, have the following advantages: carry out water-tight by two waterproof constructions, thereby guarantee that there is not breach in inside, has good sealing effectiveness, there is not again the power cable switching process, thereby avoid the risk because of the vibrations generation, improved the reliability of machine operation.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is the utility model motor sealing structure schematic diagram.
Fig. 2 is existing motor sealing structure schematic diagram.
Among the figure: 1. caulking gum, 2. full nylon water joint, 3. power cable, 4. waterproof fast joint, 5. waterproof case, 6. terminal block, 7. bolt, 8. breach.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of motor sealing structure, comprise the caulking gum 1 on the motor rear cover, corresponding power cable place is provided with full nylon water joint 2 and waterproof case 5 on motor rear cover, carry out water-tight by two waterproof constructions, thereby guarantee that there is not breach in inside, have good sealing effectiveness.
Further, be provided with waterproof fast joint 4 in the outside of motor rear cover at power cable 3 places of drawing, improve sealing effectiveness.
In the utility model, there is not switching process in the power cable of motor, thereby avoids the risk that produces because of vibrations, has improved the reliability of machine operation, and this structure adopts parts to be the standard component product, and cost is low, dependable performance.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
