Description
Technical field
The utility model relates to reducer technology field more particularly to a kind of gear reduction units of oil sealing position-adjustable.
Background technique
Retarder be it is a kind of by being enclosed in the intracorporal gear drive of rigid crust, worm-drive, pinion-endless screw transmission are formed
Individual components, the speed reduction gearing being commonly used between driving link and working machine.In prime mover and working machine or executing agency
Between play a part of to match revolving speed and transmit torque, using extremely wide in modern mechanical.It is often filled with inside speed reducer
Lubricating oil, for the lubrication and cooling between mechanical part.Oil sealing is the mechanical organ for seal grease, is usually used in mechanical biography
Motivation structure, the component for needing to lubricate in transmission parts is isolated with power output component for it, is unlikely to allow oil seepage.Major part subtracts
Shaft in fast machine is all sealed using oil sealing.Since oil sealing needs to fit closely with axis, axis when in use, needs high speed to revolve
Turn, prolonged use will lead to oil seal lip and the contact position of axis wears into ditch together, cause the failure of oil sealing oil leak.It is common
Solution be increase shaft and oil sealing contact position hardness, but when long-time after still will appear abrasion, can not be complete
It totally disappeared and remove.Whole shaft can only be replaced after there is abrasion, since shaft manufacturing cost is high, causes maintenance cost height.
Chinese patent application publication number CN202674173U, publication date are on 01 16th, 2013, entitled " high leakproofness
Worm-gear speed reducer " discloses a kind of speed reducer, and the leakproofness of speed reducer present in the solution prior art is poor to ask
Topic.But oil sealing used in the invention and prior art difference are little, still will appear and use for a long time, oil sealing wears shaft, leads
The problem of causing oil leak.
Summary of the invention
The utility model in order to overcome the shortcomings in the prior art, provides a kind of The gear deceleration of oil sealing position-adjustable
The advantages that oil sealing position of machine, the speed reducer is adjustable, and regulative mode is simple, and sealing effect is good, and adjustable range is big.
To achieve the goals above, the utility model uses following technical scheme:
A kind of gear reduction unit of oil sealing position-adjustable, characterized in that including cabinet, shaft, oil sealing, adjusting block and case
Lid；The case lid is fixed with cabinet, and the oil sealing is arranged on adjusting block；Case lid is equipped with through-hole, and the through-hole, which is equipped with, to be adjusted
Save bolt；The adjusting bolt includes sequentially connected thread segment, interlude, circular shaft section and bolt head, bolt head and thread segment
Divide the opposite sides in case lid, the circular shaft section is rotatably assorted with the through-hole on case lid, and thread segment is threadedly coupled with adjusting block,
Bolt head and case lid compress；The adjusting bolt is equipped with compressed spring, and the compressed spring is set in the centre for adjusting bolt
Duan Shang.Compressed spring end thereof contacts, another end in contact of compressed spring.The circular shaft section of the adjusting bolt and the through-hole on case lid
Rotation is matched, and guarantees that adjusting bolt can rotate freely.Adjusting bolt described in the utility model passes through compressed spring and adjusting block connects
It connects, it is ensured that in use process, compressed spring is not fallen out.When adjusting bolt relative to adjusting block back-out, due to compression
The elastic force of spring, for adjusting block far from case lid, the contact position of oil sealing and shaft is mobile to case lid direction.When adjust bolt relative to
When adjusting block precession, since compressed spring can stretch, adjusting block is close to case lid, and the contact position of oil sealing and shaft is to far from case
Lid direction is mobile.After the completion of adjusting, due to compressed spring and adjust bolt collective effect, adjusting block not in the case where by external force not
It can move, increase the reliability of oil sealing sealing.The direction of rotation for adjusting bolt is different, and the mobile direction of adjusting block is also different,
Adjusting block can also can both be adjusted to far from the movement of case lid direction to close to the movement of case lid direction according to actual selection
The moving direction of oil sealing.
Preferably, the adjusting block is equipped with circlip and baffle ring, the baffle ring is fixed with adjusting block, circlip
It is clamped with adjusting block, the oil sealing is arranged between baffle ring and circlip, and circlip and baffle ring clamp oil sealing.The gear
The internal diameter of ring is greater than the diameter of shaft herein, it is ensured that shaft is not contacted with baffle ring, will not generate friction.Outside the oil sealing
Diameter is slightly larger than the internal diameter of adjusting block, it is ensured that oil sealing and adjusting block are in close contact, and increase sealing effect.The oil sealing and shaft
It is close to, it is ensured that the sealing effect of oil sealing.Oil sealing is fixed on adjusting block by baffle ring and circlip, and fixed form can
It leans on, while can dismantle.Oil sealing relative axle is more easy to wear, it is therefore desirable to periodically be replaced, present apparatus dismounting side in replacement
Just, replacing construction is saved
Preferably, the adjusting block is equipped with tapped blind hole, the tapped blind hole and the thread segment adjusted on bolt are suitable
Match.Tapped blind hole is obstructed close to speed reducer interior side, can prevent from leaking out by tapped blind hole, guarantee the sealing of speed reducer
Property.
Preferably, being additionally provided with sealing ring on the adjusting block, the sealing ring is contacted with cabinet.Since adjusting block can be with
Mobile, adjusting block outer diameter is slightly less than the aperture of cabinet circular hole herein, can there is small gap between the two, and sealing ring can be into
The leakproofness of one step stiffening device.
Preferably, the case lid is fixed with cabinet by multiple fixing bolts.It needs to dismantle in maintenance, using bolt
Connect easy to disassemble, renewal part.
The beneficial effects of the utility model are: (1) structure is simple, it is easy to process；(2) when shaft and oil sealing joint place occur
When abrasion, the bonding position of adjustable shaft and oil sealing；(3) oil sealing is easy to adjust, fixed reliable；(4) model is adjusted in oil sealing
It encloses greatly, it can bidirectional modulation；(5) shaft dismounting, maintenance are convenient, and oil seal replacement is convenient；(6) speed reducer good airproof performance.
