Abstract
The utility model discloses an insulating properties is good, simple structure, simple to operate's insulating bearing housing, including bearing housing body and end cover, be provided with first, two through -holes on bearing housing body and the end cover, the bolt passes first, two through -holes and links firmly bearing housing body and end cover, and bearing housing body and end cover, bolt contact's position covers and is equipped with insulating spacer. Bearing housing body and end cover, bolt contact's position covers and is equipped with insulating spacer, keeps apart in order to reach insulating purpose through insulating spacer between end cover and the bearing housing body during assembly, prevents the production of shaft current, can reduce bearing vibration simultaneously, and the protection bearing is not damaged.
Description
Technical field
The utility model is related to motor manufacturing technology, and in particular to a kind of insulating bearing carrier ring.
Background technology
Motor reel electric current cannot prevent, especially particularly evident in big-and-middle-sized adjustable frequency motor, badly influence
The service life of bearing of motor.Under normal circumstances, there is the presence of lubricating oil film between rotating shaft and bearing, play a part of insulation,
Shaft current will not be produced.But when shaft voltage increases to certain numerical value, especially in motor start-up or bearing oil starvation, bearing
Interior lubricating oil film is not stably formed, and shaft voltage will puncture oil film electric discharge and form loop, and shaft current is by from bearing and rotating shaft
Metal contact passes through, and many small ruts are then burnt on bearing inner surface, and it is good fit with bearing to destroy axle, so as to
Cause the bearing cannot normal work.
In prior art, generally use insulation bearing or add insulating pad on bearing holder (housing, cover), but insulation bearing price
Costliness, maintenance cost is high, once damage the insulation bearing that need to more renew；And bearing holder (housing, cover) adds insulating pad with low cost, but knot
Structure is complicated, assemble loaded down with trivial details, and insulating pad easily causes bear vibration, damages bearing.
Utility model content
The utility model discloses a kind of good insulation preformance, simple structure, insulating bearing carrier ring easy for installation.
To achieve these goals, the technical solution adopted in the utility model is：A kind of insulating bearing carrier ring, including bearing holder (housing, cover)
Body and end cap, are provided with first and second through hole on bearing holder (housing, cover) body and end cap, bolt passes through first and second through hole by bearing holder (housing, cover) sheet
Body and end cap are connected, and bearing holder (housing, cover) body is covered with insulating cell with end cap, the position of threaded bolt contacts.
Bearing holder (housing, cover) body is covered with insulating cell with end cap, the position of threaded bolt contacts, end cap and bearing holder (housing, cover) body during assembling
Between isolate to reach the purpose of insulation by insulating cell, prevent the generation of shaft current, while bear vibration can be reduced, protect
Shield bearing is not damaged by.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
A kind of insulating bearing carrier ring, including bearing holder (housing, cover) body 10 and end cap 20, are provided with bearing holder (housing, cover) body 10 and end cap 20
First and second through hole 11,21, bolt 30 is connected bearing holder (housing, cover) body 10 and end cap 20 through first and second through hole 11,21, bearing holder (housing, cover)
The position that body 10 is contacted with end cap 20, bolt 30 is covered with insulating cell 12.Bearing holder (housing, cover) body 10 connects with end cap 20, bolt 30
Tactile position is covered with insulating cell 12, isolates to reach by insulating cell 12 between end cap 20 and bearing holder (housing, cover) body 10 during assembling
To the purpose of insulation, the generation of shaft current is prevented, while bear vibration can be reduced, protection bearing is not damaged by；Simultaneously can be with
Be effectively prevented iron filings, the failure of insulation that dust causes.
Preferably, the uniform integral type lining plastic of insulating cell 12 is in the outer surface of bearing holder (housing, cover) body 10 and the hole of first through hole 11
On wall.Lining plastic process is carried out to bearing holder (housing, cover) body 10 with special mould and plastic coating process, insulating cell 12 and bearing holder (housing, cover) is made
Body 10 is integral type, significantly reduces the vibration of bearing, and integral plastic lined structure, good looking appearance, I＆M side
Just.
Further, the end of bearing holder (housing, cover) body 10 is provided with flange 13, and first through hole 11 is arranged on flange 13, flange 13
The assembling being provided with beneficial to bearing holder (housing, cover) body 10 and lid 20.
Claims (3)
