Abstract
The utility model relates to a motor and discloses a motor provided with a waterproof structure. The existing motor has poor waterproof effect, so that the water can flow into the motor through a motor shaft easily. A waterproof cover rubs with the motor shaft to generate noise and vibration, so that the performance is reduced, the waterproof cover can deform easily, and the motor cannot operate smoothly, thereby influencing the performance. The motor provided with the waterproof structure comprises a motor box body, the motor shaft, an end cover and a waterproof cover, wherein the motor shaft is arranged in the motor box body in a penetrating way, the end cover is fixedly arranged at the right end of the motor box body, and the waterproof cover is arranged at the outer side of the end cover and is sleeved on the motor shaft. The motor provided with the waterproof structure is characterized in that an arc-shaped diversion edge is arranged at the end cover; the waterproof cover is in a bowl shape, and the diversion edge of the end cover internally stretches into the waterproof cover. The right side of the arc-shaped diversion edge is high so as to prevent the water from entering the motor chamber of the end cover along the edge cover, the water can slide to the outside of the end cover along the diversion edge so as to avoid entering the end cover, meanwhile, as the diversion edge is arranged in the waterproof cover, water, impurities and the like can be prevented from entering the motor through the gap of the motor shaft and the end cover.
Description
Technical field
The utility model relates to a kind of motor.
Background technology
At present, the existing used motor of air conditioner as shown in Figure 1, include motor shaft 11 and be arranged on the end cap 5 of motor shaft 11 outer ends, bearing 8, bearing chamber 6 and motor shaft stretch out hole 10, bucker 1, taper introducing port 2, secure fit face 3, the assembling and positioning face 4 that is used for the location of bearing 8, its fit are that the taper introducing port 2 of bucker 1 puts in the motor shaft that end cap 5 makes and stretches out in the hole 10, and its assembling and positioning face 4 contacts with the outer face of bearing 8.Bucker 1, with its taper introducing port 2, secure fit face 3, the 4 integral molded plastic moulding of assembling and positioning face.The shortcoming that this structure exists is that waterproof effect is bad, and water still can stretch out hole 10 by motor shaft easily and flow to motor.Bucker 1 is easy to stretch out hole 10 with motor shaft and produces friction, causes wearing and tearing and produce rubbish to enter motor shaft, produces noise and vibration, makes decreased performance.Because bucker 1 is an elastomeric material, when installing, make 4 distortion of assembling and positioning face easily, cause motor rotation not smooth, influence performance.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, and a kind of motor of the water-bound of setting up defences is provided, and is good to reach water resistance, the purpose of stable work in work.For this reason, the utility model is taked following technical scheme.
A kind of motor of the water-bound of setting up defences, comprise motor case body, be arranged in motor case body motor shaft, be fixedly arranged on the end cap of motor case body right-hand member and be located at the end cap outside and be socketed in bucker on the motor shaft, it is characterized in that: described end cap is provided with arc water conservancy diversion limit; Described bucker is bowl-shape, stretches in the bucker in the water conservancy diversion limit of end cap.Right side, arc water conservancy diversion limit height stops during water enters motor cavity in the end cap along end cap, and water, is avoided entering in the end cap along the landing of water conservancy diversion limit to end cap.The water conservancy diversion limit is positioned at bucker simultaneously, avoids water, impurity etc. to enter in the motor by the gap of motor shaft and end cap.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
The middle part of bucker is provided with pilot hole, and described motor shaft is provided with the location notch that matches with the bucker pilot hole.Bucker is stuck in finishes assembling in the pilot hole, easy to assembly and since bucker not with the end cap friction, avoid abrasive particle to enter motor shaft, prevent to produce noise and vibration, guarantee properties of product.
Described end cap is bent to form the bearing chamber that matches with bearing to the right, turns up after bearing chamber closes up to form arc water conservancy diversion limit.End cover structure is simple, adopts arc water conservancy diversion limit can prevent that stress is concentrated, and easy to process.
The middle part of end cap is provided with the arc axis hole with the motor shaft matched in clearance, and described axis hole is positioned at the inboard on water conservancy diversion limit.The inboard on end cap water conservancy diversion limit is an axis hole, and axis hole is similar to water conservancy diversion limit shape, makes the wall thickness between axis hole and the water conservancy diversion limit even.
Described bucker is the rubber waterproof cover, and its openend outside is provided with the dash limit of turning up.To the location notch of motor shaft, easy to assembly, the location is reliable by the strain clamping for the rubber waterproof cover.The dash limit of turning up can be avoided the water in the bucker outside to fall into motor cover covering, and prevents that overflowing the water conservancy diversion limit behind the hypervolia enters in the motor cavity water.
Beneficial effect: the water conservancy diversion limit stops during water enters motor cavity in the end cap along end cap; Because the water conservancy diversion limit is positioned at bucker, reduce water and enter in the water conservancy diversion limit of end cap, further avoid water, impurity etc. to enter in the motor case.To the location notch of motor shaft, easy to assembly, the location is reliable by the strain clamping for the rubber waterproof cover.

Embodiment
Below in conjunction with Figure of description the technical solution of the utility model is described in further detail.
As shown in Figure 2, the utility model comprises motor case body 10, is arranged in the motor shaft 1 of motor case body 10, is fixedly arranged on the end cap 2 of motor case body 10 right-hand members and is located at end cap 2 outsides and is socketed in bucker 3 on the motor shaft 1, end cap 2 is bent to form the bearing chamber 7 that matches with bearing to the right, and turning up after bearing chamber 7 closes up forms arc water conservancy diversion limit 4; The middle part of end cap 2 is provided with the arc axis hole 8 with motor shaft 1 matched in clearance, and axis hole 8 is positioned at the inboard on water conservancy diversion limit 4, and the shape of axis hole 8 and water conservancy diversion limit 4 are similar to make the wall thickness between axis hole 8 and the water conservancy diversion limit 4 even, prevents stress, is convenient to processing and manufacturing.Bucker 3 is bowl-shape, and the openend outside is provided with the dash limit 9 of turning up, and stretches in the bucker 3 in the water conservancy diversion limit 4 of end cap 2, and the middle part of bucker 3 is provided with pilot hole 5, and motor shaft 1 is provided with the location notch 6 that matches with bucker pilot hole 5; For the ease of processing with install, bucker 3 is a rubber waterproof cover 3, and by its strain, clamping is gone in the location notch 6 on the motor shaft 1, finishes assembling.
After other parts of motor are finished assembling, carry out the assembling of bucker 3 at last.Only bucker 3 need be pushed in the location notch 6 along motor shaft 1 gently during assembling and get final product.
