Abstract
The utility model belongs to the technical field of motors, and especially relates to a waterproof rear cover structure with a fan motor. The structure comprises a motor shaft and a rear cover. One end of the motor shaft passes through the central hole of the rear cover and extends out of the rear cover. The motor shaft out of the rear cover is fixedly provided with a fan. The motor shaft is supported on the central hole of the rear cover through a bearing. A side of the bearing or two sides of the bearing are respectively provided with waterproof devices. Through arranging two oil seals and arranging lubricating oil or lubricating grease between the two oil seals, water is prevented from entering the motor from gaps between the motor shaft and the rear cover, thereby having a waterproof effect. The structure is simple in structure and low in cost. The lubricating oil or the lubricating grease has lubricating effect, improving quality of the motor. The structure solves potential safety hazard of an existing motor caused by inflow of water, so safety performance of motor use is greatly improved, and service life of the motor is prolonged.
Description
Technical field:
The utility model belongs to technical field of motors, refers in particular to a kind of waterproof rear cover structure with fan electromotor.
Background technology:
At present, band fan electromotor on market does not all have waterproof construction, particularly use in the more area of some rainwater, as: rainwater enters in motor from the gap between motor shaft and motor rear cover, cause the phenomenons such as electric leakage to have very large potential safety hazard, or cause motor to burn out because the gap between rainwater motor shaft and motor rear cover enters in motor, have a strong impact on productive life, reduced the useful life of motor and the quality of motor.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure, waterproof rear cover structure with fan electromotor of making motor energy waterproof.
The utility model is achieved in that
A kind of waterproof rear cover structure with fan electromotor, include motor shaft, bonnet, stretch out outside bonnet through the centre bore on bonnet one end of motor shaft, on motor shaft outside bonnet, be installed with fan, motor shaft is bearing in by bearing on the centre bore of bonnet, is respectively arranged with water-tight device in a side of bearing or the both sides of bearing.
Above-mentioned water-tight device is: include two side inner oil seal and outer oil seals that are disposed on bearing, the inner ring of inner oil seal and outer oil seal is sleeved on that motor shaft is outer, outer ring and center bore inner wall are combined closely, and is provided with lubricating oil or lubricating grease between two oil sealings.
Above-mentioned inner oil seal and outer oil seal are lip oil sealing, and arrange in opposite directions.
Above-mentioned bearing and outer oil seal are separately positioned on the both ends of the centre bore of bonnet, and inner oil seal is near bearing setting.
Above-mentioned water-tight device is: include the inner oil seal and the outer oil seal that are arranged on bearing both sides, the inner ring of inner oil seal and outer oil seal is sleeved on that motor shaft is outer, outer ring and center bore inner wall are combined closely, between inner oil seal and bearing, be provided with lubricating oil or lubricating grease between bearing and outer oil seal.
Above-mentioned inner oil seal and outer oil seal are separately positioned on the both ends of centre bore on bonnet.
Above-mentioned inner oil seal and outer oil seal are lip oil sealing, and arrange in opposite directions.
The advantage that the utility model is given prominence to is compared to existing technology:
1, the utility model is by the setting of two oil sealings, and lubricating oil or lubricating grease is set between two oil sealings, avoid water to enter in motor from the gap between motor shaft and bonnet, play the effect of waterproof, and simple in structure, cost is low, and the lubricating oil of setting or lubricating grease play lubricated effect, has improved quality and the quality of motor;
2, the utility model has solved the potential safety hazard that existing motor causes because of water inlet, and the security performance that motor uses improves greatly, has extended the useful life of motor;
3, the utility model maintenance cost is low, and it is convenient to change, good water-proof effect.
