Abstract
There is recessed put to get rid of the rotating shaft of oily tooth group's spindle nose and belong to technical field of mechanical transmission.Put tooth group 2, the oil sealing at two ends section 3 by axis body 1, the recessed of two ends and constituted.It is recessed to put tooth group 2 between axis body 1 and oil sealing section 3, made on the body of axis body 1.The recessed crest top land for putting tooth group 2 is flushed with the surface of axis body 1, is not hindered parts on axle and is loaded and unloaded.The recessed tooth group 2 and oil sealing section 3 put has an overlay segment 4, it is ensured that fall into recessed put in 2 sections of tooth group along the dirty lubricating oil in oil sealing side.It can effectively prevent lubricating oil from being leaked outside from seal clearance.For machine driving.
Description
Technical field
Machine driving.
Background technology
The shaft head seal part of various mechanical drive shafts, has outside framework oil seal and the various informative major class of sealing ring two.In order to subtract
Few lubricating oil permeates into seal clearance, disc is often added at seal in rotating shaft, using centrifugal force rotating shaft surface
Oil is radially thrown away.Oil return thread groove is also set in seal pair, using the axial pumping effect of thread groove, makes desire is past to leak
Defeated time annular seal space of lubricating oil.But for swashing the oil for splashing and being flowed down along oil sealing side wall, it is but close without effectively preventing it from entering
Seal the structural element in gap.
The content of the invention
There is recessed put to get rid of the rotating shaft technical problem to be solved of oily tooth group's spindle nose and be：Make to flow down and rotating shaft surface along oil sealing side wall
Lubricating oil, in axis of rotation, it is difficult to enter seal clearance.
The technical scheme of use is：Oil sealing medial surface in rotating shaft is made recessed put and is got rid of oily tooth group with inner.
Have it is recessed put get rid of the rotating shaft (Fig. 1) of oily tooth group's spindle nose by axis body 1, two ends it is recessed put tooth group 2, two ends oil sealing 3 structures of section
Into.It is recessed to put tooth group 2 between axis body 1 and oil sealing section 3, made on axis body 1.The recessed crest top land for putting tooth group 2 and the surface of axis body 1
Flush, do not hinder the handling of parts on axle.The recessed tooth group 2 and oil sealing section 3 put has an overlay segment 4, it is ensured that along the dirty profit in oil sealing side
Lubricating oil falls into recessed put in 2 sections of tooth group.
The beneficial effect for having the recessed rotating shaft put and get rid of oily tooth group's spindle nose is：The recessed lubricating oil put in 2 sections of tooth group is fallen into, because of its tooth
Radially there are enough teeth high in rotating shaft, lubricating oil can be stirred, it is turned with tooth spiral, produce centrifugal force and radially throw away, prevent
Enter axially into seal clearance.
Brief description of the drawings
Fig. 1 is that have the recessed pivot structure schematic diagram put and get rid of oily tooth group spindle nose.In figure：1- axis bodies；2- is recessed to put tooth group；3- oil sealings
Section；4- overlay segments.
Embodiment
The preferred embodiment of the application is realized, details are as follows for compares figure 1：
Recessed tooth group 2 of putting is cylindrical straight gear trapezoid cross section.In order to strengthen oil-throwing performance, the number of teeth is as far as possible more, and tooth height will try one's best
Greatly；But to make lubricating oil there is the time to fall between cog, must there is enough backlashes again.Backlash should improve and increase with axle speed
Plus.The number of teeth should increase and increase with the diameter of axle.Monodentate 10~20mm of length, tooth high 3mm, tooth top width 1mm, the wide 3mm of tooth root.Adjacent two tooth
Tooth root spacing 4mm, and sawteeth several weeks uniform rounding of circle.The length of overlay segment 4 is equal to the ending segment length of tooth length.
Device correlation parts on axis body 1.Oil sealing is installed in oil sealing section 3.
Claims (2)
1. there is the recessed rotating shaft put and get rid of oily tooth group spindle nose, including axis body (1), the oil sealing section (3) at two ends, it is characterized in that：By axis body
(1), the recessed of two ends puts tooth group (2), oil sealing section (3) composition at two ends；It is recessed put tooth group (2) between axis body (1) and oil sealing section (3) it
Between, made on axis body (1)；The recessed crest top land for putting tooth group (2) is flushed with axis body (1) surface；It is recessed to put tooth group (2) and oil sealing section
(3) there is an overlay segment (4).
2. according to claim 1 have the recessed rotating shaft put and get rid of oily tooth group spindle nose, it is characterized in that：It is recessed to put tooth group (2) for cylinder
Straight-tooth trapezoid cross section；Monodentate 10~20mm of length, tooth high 3mm, tooth top width 1mm, tooth root wide 3mm, adjacent two teeth tooth root spacing 4mm.
