Abstract
The invention discloses a waterproof structure of a motor, which comprises a motor end cover (1) and a rotating shaft (3) penetrating out from a through hole (21) in a bearing chamber (2) on the motor end cover (1), wherein a bearing (5) is arranged in the bearing chamber (2) and used for supporting the rotating shaft (3), a waterproof cover (4) is arranged on the rotating shaft (3) of the motor and is covered outside the bearing chamber (2), a boss (6) protrudes outwards is arranged on the top surface of the bearing chamber (2), extends into the interior of the waterproof cover (4) and is matched with the rotating shaft (3) of the motor, and a water baffling ring (7) is arranged on a position above the top of the lug boss (6) and in the waterproof cover (4), and is sleeved on the rotating shaft (3) of the motor. The waterproof structure is especially suitable for an outdoor motor; and according to the waterproof structure, water flow is effectively prevented from flowing into the motor, normal working of the motor is ensured, and service life of the motor is prolonged.
Description
Technical field:
The present invention relates to a kind of waterproof construction of motor, be 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 motor, the especially outdoor use installed; 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 outside end cap, to scurry into axle easily 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 invention is to provide a kind of motor new waterproof structure, 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 objective of the invention is to be achieved through 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, and 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, processes 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 processed by metal material.
Above-mentionedly describedly on the end of boss, protrude flange, flange is positioned at the below of retaining ring.
The present invention compared with prior art has 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) in the top position of retaining ring, rotating shaft, be provided with location notch, 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, processes with elastomeric material, and is with low cost, is prone to assembling.
Description of drawings:
