Abstract

The utility model relates to a small waterproof motor used in the fields such as fountain spray irrigation. The small waterproof motor comprises a motor body and a motor fixed inside the motor body, wherein two ends of the motor body are provided with a front cover and a rear cover; the front cover and the rear cover are connected with two ends of the motor body respectively via a first O-type sealing ring and a second O-type sealing ring; the lead wire of the motor are led out via a through hole in the rear cover; the center of the outer wall of the rear cover is provided with an inner thread groove; the inner thread groove is internally provided with a sealing nut; a sealing ring is arranged in the place where the sealing nut and the inner thread groove are connected; a main shaft is sleeved and fixed with the rotary shaft of the motor; the main shaft is sleeved with the front cover via a sliding bearing; and a skeleton sealing ring is arranged in the place where the main shaft and the inner wall of the front cover are connected. According to the small waterproof motor, motor body sealing is used, reasonable matching among the sliding bearing, the skeleton sealing ring, the O-type sealing rings and the like are adopted, the motor is tightly waterproof, frictional resistance applied to the motor bearing is minimal, the efficiency is high, and the service life is long.

Description

Small-sized waterproof machine

Technical field

The utility model relates to a kind of waterproof machine, particularly relates to a kind of small-sized waterproof machine using for fields such as fountain sprinkling irrigations.

Background technology

Waterproof machine is mainly used for driving movable machinery equipment under water, as movable machinery of fountain spray irrigation system etc., because motor need to be arranged under water, and the operation of working in water for a long time, so ensure the tight water proofing property of motor, particularly motor output revolving shaft, due to ceaselessly motion, the most easily causes sealing bad and leaks, and therefore movable sealing is a crucial problem.

The motor using due to fountain sprinkling irrigation equipment is generally micro-machine, the motor using in prior art, and sealing is not often very desirable; Sealing tension, can cause the suffered frictional resistance of motor bearings too large, causes motor output loss too large, causes electric efficiency greatly to reduce, and not only wastes energy, and the serious motor that also can cause can not turn round; Sealed pine, but can cause motor to infilter and anhydrate in the process of operation, damage motor, the life-span of motor is reduced, strengthen cost, therefore, the reasonability design of the sealing to waterproof machine is a major issue, not only needs to ensure the strict water-tight performance of motor, also will make the suffered resistance minimum of motor bearings simultaneously, be convenient to flexible rotating, reduce the loss of electric machine.

Summary of the invention

The utility model is in order to address the above problem, a kind of use body sealing is provided, and adopt the reasonable coordinations such as sliding bearing, backbone sealing ring and O RunddichtringO, when making the tight waterproof of motor, the frictional resistance minimum that motor bearings is suffered, and efficiency is high, the small-sized waterproof machine of long service life.

The technical solution of the utility model is:

A kind of small-sized waterproof machine, comprise body and be fixed on the motor in body, the two ends of body are provided with protecgulum and bonnet, described protecgulum is connected with body two ends with the 2nd O RunddichtringO by an O RunddichtringO respectively with bonnet, motor down-lead is drawn by the through hole of bonnet, the center of described rear cover outer wall is provided with an internal thread groove, in internal thread groove, be provided with a sealing nut, the junction of described sealing nut and internal thread groove is provided with sealing ring, in the rotating shaft of described motor, be fixed by socket a main shaft, described main shaft is socketed in protecgulum by sliding bearing, the junction of described main shaft and protecgulum inwall is provided with a backbone sealing ring.

Described machine shaft is provided with an abutment sleeve, and machine shaft is fixedly connected with by a pin with main shaft.

Front end in described body is also provided with a bearing pedestal, is provided with a rolling bearing in bearing pedestal, and described collar bush is connected in rolling bearing, and bearing pedestal is fixedly connected by hold-down screw and body inwall flange.

The front end outer wall of described body is provided with outer wall flange, and protecgulum is connected by hold-down nut with outer wall flange.

Useful good effect of the present utility model is:

The utility model by being fixed by socket a main shaft on machine shaft, and be connected with bearing by rolling bearing, and the protecgulum place at body arranges sliding bearing and backbone sealing ring, in increasing tight water resistance, reduce to greatest extent the friction of motion resistance of motor bearings, make the delivery efficiency of motor high, loss is few, and increase O RunddichtringO by the protecgulum at body and bonnet place, in not affecting motor operation, for increasing, motor integral waterproofing performance ensures, and the utility model removes and installs conveniently, easy access and replacing, cost is low.
