Waterproof structure of motor

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: [0001] The invention relates to a waterproof structure of a motor, especially suitable for outdoor motors, and is a technical improvement on the existing waterproof structure of the motor. Background technique: [0002] At present, for motors installed axially, especially for outdoor use, the primary solution is to waterproof the shaft hole. Most motors are installed on the shaft with a waterproof cover, but due to the accumulation of water, it is easy to enter the In the shaft chamber, water vapor can condense into water droplets in the waterproof cover, which can flow into the motor along the shaft. This structure cannot play a role of complete waterproofing, which will affect the normal operation of the motor. Invention content: [0003] The purpose of the present invention is to provide a new type of waterproof structure of the motor, which has a simple structure and can effectively prevent water from entering the motor, so as to ensure the normal oper...
