Abstract
The utility model discloses a waterproof sealing ring of a motor. The waterproof sealing ring consists of a mounting portion (1) at the front end and a water retaining portion (4) at the rear end, wherein the mounting portion (1) at the front end is provided with a cavity (11) inside and sleeved outside a bearing chamber (3) of a motor end cap (2), a rotating shaft (6) can penetrate through a shaft hole (12) arranged in the middle of the water retaining portion (4) at the rear end, the cavity (11) is communicated with the shaft hole (12), the water retaining portion (4) at the rear end radially expands outwards gradually, and a groove (5) is formed at the joint of the outer side surface of the water retaining portion (4) and the bottom end surface of the mounting portion (1). The waterproof sealing ring has simple structure, easy installation, low manufacturing cost and perfect waterproof effect, effectively prevents radial water flowing to the rotating shaft of the motor and entering the motor bearing chamber, protects motor bearings and then guarantees operation reliability of the motor.
Description
Technical field:
The utility model relates to a kind of waterproof grommet of motor.
Background technology:
Traditional motor, gapped between machine shaft and end cap, needs are installed the sealing ring of dustproof and waterproof, but in the existing sealing ring, some sealing ring tightness are bad, and some prevent that in order to reach dust or water from infiltrating in the motor, complicated structure is set, influences the operate as normal of motor.
Popular on the market a kind of sealing ring uses vinyl cover as the water-tight dustproof construction, and vinyl cover is locked and rotates with axle in rotating shaft, but the waterproof effect imperfection, aging easily and easy the damage; The labyrinth structure of employing or other more complicated hermetically-sealed constructions are also arranged, and complex manufacturing process is installed also very inconvenience, and cost is higher.
Summary of the invention:
In order to address the above problem, the purpose of this utility model is to provide a kind of simple in structure, waterproof grommet that the motor that easy manufacturing cost is lower, waterproof effect is desirable is installed.
The purpose of this utility model is achieved by following technical proposals.
A kind of waterproof grommet of motor, form by the installation portion of front end and the retaining section of rear end, the installation portion the inside of front end is provided with cavity and is nested in the bearing chamber outside of electric motor end cap, the axis hole that setting can supply rotating shaft to pass through in the middle of the retaining section of rear end, cavity is communicated with axis hole, radially open gradually outward the retaining section of rear end, and the joint of the bottom face of the lateral surface of retaining section and the installation portion of front end forms groove.
The installation portion of above-mentioned described front end is cylindric.
The retaining section lateral surface of above-mentioned described rear end is horn-like.
The medial surface of above-mentioned described retaining section can be the face of cylinder, also can be taper seat.
Above-mentioned described installation portion and retaining section rubber integrated injection molding.
The beneficial effects of the utility model are: 1) simple in structure, to install easily, and low cost of manufacture adopts the rubber manufacturing to have certain elasticity, and not fragile, the life-span is longer; 2) rear end of sealing ring forms open outward tubaeform retaining section; the joint of the bottom face of the lateral surface of retaining section and the installation portion of front end forms groove; radially flowing water is collected in the groove and is discharged; waterproof effect ideal radially; effectively having stoped radially, flowing water flows into the motor the inside along machine shaft; protect motor, and then guaranteed the functional reliability of motor.
