Abstract
The utility model discloses an internal rotor motor for a blower fan, comprising a cast iron shell (1), a plastic cover (2), a rotating shaft (3), and a waterproof cover (5). An end part of the rotating shaft (3) extends out of the plastic cover (2) and is provided with a threaded connecting rod (4). The waterproof cover (5) covers the end part of the rotating shaft (3). The threaded connecting rod (4) is sleeved with a first vibration isolator (6). One surface of the first vibration isolator (6) is attached to an external top surface (7) of the waterproof cover (5), and the other surface of the first vibration isolator (6) is provided with a plurality of elastic columns (10) uniformly and circumferentially distributed. An external surface of the waterproof cover (5) is provided with a plurality of reinforcing ribs (11) distributed in radial manner. The internal rotor motor is applicable in an operational environment requiring a high waterproof grade and is guaranteed in performance in the operational environment requiring a high waterproof grade.
Description
Technical field
The utility model relates to the blower fan technical field, specifically is a kind of blower fan inner rotor motor.
Background technology
A kind of blower fan inner rotor motor is arranged at present, it comprises cast housing, plastic jacket and rotating shaft, cast housing and plastic jacket axially are assembled together along rotating shaft, plastic jacket is provided with the through hole that stretches out for roller end, roller end is provided with for the whorl brace rod that connects wind wheel, whorl brace rod is used for axially locking wind wheel, because said structure only can reach the IPx4 classification of waterproof, so be not suitable for the environment for use of the higher classification of waterproof requirement of requirement.
The utility model content
The technical problems to be solved in the utility model is, a kind of blower fan inner rotor motor that is applicable to require the environment for use of high classification of waterproof requirement is provided, thereby ensures that blower fan requires performance in the environment for use with inner rotor motor at high classification of waterproof.
The technical solution of the utility model is, the utility model blower fan inner rotor motor, it comprises cast housing, plastic jacket and rotating shaft, cast housing and plastic jacket axially are assembled together along rotating shaft, plastic jacket is provided with the through hole that stretches out for roller end, roller end is provided with for the whorl brace rod that connects wind wheel, it also comprises the waterproof cover that roller end is covered, waterproof cover is provided with the first axial hole, the second axial hole that supplies whorl brace rod to pass, the end face of rotating shaft is provided with the axial projection of passing the first axial hole, be arranged with the first vibration isolator on the whorl brace rod, one surface of the first isolation cushion fits with the outer end face of waterproof cover, another surface of the first isolation cushion is provided with a plurality of circumferential equally distributed elastics, and the outer surface of described waterproof cover is provided with many reinforcements that distribute radially.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the utility model blower fan is provided with the waterproof cover that roller end is covered with inner rotor motor, like this, when not affecting the motor self performance, carry out waterproof by waterproof cover, make classification of waterproof of the present utility model can reach IPx6, so the utlity model has the advantage of the environment for use that is applicable to require high classification of waterproof requirement, thereby ensure the blower fan performance of inner rotor motor in high classification of waterproof requirement environment for use, the first vibration isolator can effectively intercept the vibrations of wind wheel simultaneously, elastic on the first isolation cushion can further intercept the vibrations of wind wheel, and at waterproof cover the intensity that reinforcement can the Effective Raise waterproof cover is set, prevent the waterproof cover distortion.
As improvement, described waterproof cover is truncated cone-shaped, and the inner top surface of waterproof cover and the end face of rotating shaft are affixed; Like this, the waterproof cover water guide of truncated cone-shaped is faster, more is conducive to the raising of the utility model water resistance.
As improvement, waterproof cover is aluminium lid, and like this, aluminium lid is corrosion-resistant, and intensity is good, and long service life more is conducive to the raising of the utility model life-span and reliability.
As improvement, be provided with the second vibration isolator between the inner top surface of described waterproof cover and the end face of rotating shaft, like this, have better vibration isolating effect, more be conducive to the raising of the utility model life-span and reliability.
