Abstract
The utility model discloses a water-proof structure for a motor, which comprises a motor end cover (1) and a rotating shaft (3) penetrating out from a through hole (21) of a bearing chamber (2) on the end cover (1), wherein a bearing (5) is mounted in the bearing chamber (2) for supporting the rotating shaft (3); a waterproof cover (4) is mounted on the motor rotating shaft (3) and covered outside the bearing chamber (2); a lug boss (6) outwardly protruding is arranged on the top surface of the bearing chamber (2), and extends into the waterproof cover (4) to match with the motor rotating shaft (3); and a water retaining ring (7) is arranged at the top of the lug boss (6) and inside the waterproof cover (4), and is sleeved on the motor rotating shaft (3). The water-proof structure for the motor is particularly applicable to an outdoor motor to effectively prevent water from entering a shaft chamber along the end cover, thereby guaranteeing the normal working of the motor, and prolonging the service life of the motor.
Description
Technical field:
The utility model relates to a kind of waterproof construction of motor, is particularly useful for outdoor motor, is the technological improvement to existing waterproof structure for motor.
Background technology:
At present, axially go up the motor of installing, especially the motor of outdoor use, primary what solve is the water-proof function at axis hole place, and most of motor adopts bucker to be installed in the rotating shaft, but since ponding to scurry into axle easily outside end cap indoor, steam can condense into the globule in bucker simultaneously, can flow into motor along rotating shaft, this structure can not play complete waterproof effect, influences the motor operate as normal.
Summary of the invention:
The purpose of this utility model provides a kind of motor new waterproof structure, and it is simple in structure, effectively stops current to be scurried in the motor, guarantees the motor operate as normal, prolongs electrical machinery life.
The purpose of this utility model is achieved by following technical proposals.
A kind of waterproof construction of motor, comprise electric motor end cap and the rotating shaft that passes from the through hole of end cap upper bearing (metal) chamber, Bearing Installation is in bearing chamber and supporting revolving shaft, bucker is installed on the machine shaft and covers on the outside of bearing chamber, at the end face of bearing chamber to being protruded with boss, boss is enclosed within the machine shaft outside and cooperates with machine shaft, and boss stretches out into inside bucker.
The over top position of above-mentioned described boss, the inside of bucker are provided with retaining ring, and retaining ring is sleeved on the machine shaft.
Above-mentioned described boss is an annular.
Above-mentioned described retaining ring is an O shape, makes with elastomeric material.
Be provided with location notch in above-mentioned described top position at retaining ring, the rotating shaft, split washer is stuck in the location notch, and bucker is pressed on the split washer.
Above-mentioned described split washer is made by metal material.
Above-mentionedly describedly protrude flange on the end of boss, flange is positioned at the below of retaining ring.
The utility model compared with prior art, have following effect: 1) at the end face of bearing chamber to being protruded with boss, boss stretches out into cooperating to the bucker the inside and with machine shaft, in the over top position of boss, the inside of bucker retaining ring is set, retaining ring is sleeved on the machine shaft, and is simple in structure, effectively stops current to scurry into motor internal, guarantee the motor operate as normal, prolong electrical machinery life; 2) be provided with location notch in the top position of retaining ring, rotating shaft, split washer is stuck in the location notch, and bucker is pressed on the split washer, further sealed electric-motor, and flange is set on the boss, make motor be difficult for water inlet; 3) retaining ring is an O shape, makes with elastomeric material, and is with low cost, easily assembling.
