Abstract
This utility model relates to a kind of seven groove labyrinth bearing cover plates, including closure portion and flange end, flange end is arranged on closure portion excircle, the multiple locking hole of circumference uniform distribution on flange end, closure portion is provided with wears shaft through-hole, and wearing the inwall of shaft through-hole and being provided with seven roads is labyrinth seal groove.Described seven roads are that any one road sealing groove degree of depth of non-edge in labyrinth seal groove is more than other seal groove degree of depth.Wearing of closure portion, the seal groove that seven roads are labyrinth-like is set on shaft through-hole, labyrinth seal groove effectively prevents wearing spindle oil and reveals and abrasion, coordinate any one road sealing groove degree of depth of non-edge more than other seal groove degree of depth, improve sealing property further, increase the service life.
Description
Technical field
This utility model relates to a kind of bearing cover, a kind of seven groove labyrinth bearing cover plates.
Background technology
General bearing is respectively provided with oil lubrication, and wherein lubricating oil is easily along wearing axle leakage, causes lubricant pollution and axle
Hold lack of lubrication, existing be typically employed in bearing cover in install oil sealing additional, oil-sealing sleeve is connected on to wear and prevents wearing spindle oil on axle and let out
Dew, but oil sealing life-time service weares and teares, air slaking cause seal failure, there is serviceability hidden danger.
Summary of the invention
For the deficiency of bearing cover oil sealing sealing of the prior art, this utility model provide a kind of compact conformation,
Simply, good sealing effect, service life length seven groove labyrinth bearing cover plates.
The beneficial effects of the utility model are: a kind of seven groove labyrinth bearing cover plates, including closure portion and flange end, flange end
Being arranged on closure portion excircle, the multiple locking hole of circumference uniform distribution on flange end, closure portion is provided with wears shaft through-hole, wears shaft through-hole
Inwall to be provided with seven roads be labyrinth seal groove.
Further, described seven roads are that any one road sealing groove degree of depth of non-edge in labyrinth seal groove is more than other sealings
Groove depth.
Cover plate is connected by the locking hole locking of flange end to be installed, and installs stable；Arrange on shaft through-hole wearing of closure portion
Seven roads are the seal groove of labyrinth-like, and labyrinth seal groove effectively prevents wearing spindle oil and reveals and abrasion, coordinates any of non-edge
One seal groove degree of depth, more than other seal groove degree of depth, improves sealing property further, increases the service life.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: closure portion 1, flange end 2, locking hole 3, wear shaft through-hole 4, labyrinth seal groove, 5.
Detailed description of the invention
It is described further below in conjunction with drawings and Examples.
Shown in Fig. 1: a kind of seven groove labyrinth bearing cover plates include closure portion 1 and flange end 2, and flange end 2 is arranged at closure portion 1
On excircle, the multiple locking hole of circumference uniform distribution 3 on flange end 2, closure portion 1 is provided with wears shaft through-hole 4, wears the inwall of shaft through-hole 4
Being provided with seven roads is labyrinth seal groove 5.Seven roads are that any one road sealing groove degree of depth of non-edge in labyrinth seal groove is more than other
The seal groove degree of depth.
