Description
Technical field
It is the present invention relates to gearbox drive technical field more particularly to a kind of without mode connects for screw and with eccentric adjustable mechanism
Worm-cam reduction box.
Background technology
Worm-cam reduction box is that a kind of input shaft turns around, and output shaft turns 1/n（N is integer）The equipment of circle, in order to carry
In high precision, together with cam needs are brought into close contact with roller, but can not kill, in case frictional force between the two is excessive,
When roller runs, part of damage, due to the error for fabricating, it is difficult to ensure that the tolerance of each part all meets the requirements, Duo Geling
Part is combined, and will also result in error accumulation, in order to eliminate error, removes the gap between roller and cam, and need to use can
The structure of cam position is adjusted, by cam fine setting in all directions, itself and roller is fit together.
At present, the worm-cam reduction box of close structural is by screw 1, taper roll bearing 2, end cap 3, camshaft 4, O-shaped
The parts such as rubber seal 5, cam 6, space collar 7, open end cap 8, lip-type packing 9, casing 10, roller 11 are constituted, end
Lid 3 and open end cap 8 are used for positioning cone roller bearing 2, determine that circular cone is rolled by the thickness of match grinding end cap and open end cap
The clearance of sub- bearing, meanwhile, the thickness of end cap and open end cap after part is measured, can be finely tuned come match grinding by dimension chain,
Adjustable taper roll bearing 2, camshaft 4 and the overall side-play amount in axial direction of cam 6, make cam be laterally moved to Theoretical Design position
Put, but this structure cannot realize cam radial direction fine setting, it is impossible to ensure that cam and roller 11 are fitted by the square, it is impossible to eliminate due to
The error that manufacture and assembling are caused, causes indexing accuracy not high, and match grinding is not suitable for batch production.And due to end cap, open
Mouth end cap and screw protrusion casing, cause the installing space of casing to increase.Therefore, prior art has the following disadvantages：1. connect
Screw and end cap quantity are excessive, cause manufacturing cost to increase；2. attachment screw and end cap protrusion casing, cause reduction box to install empty
Between it is excessive, install inconvenience；3. the gap between reduction box roller and cam cannot be eliminated, causes indexing accuracy not high.
The content of the invention
It is an object of the invention to overcome drawbacks described above, there is provided a kind of worm screw without mode connects for screw and with eccentric adjustable mechanism
Cam deceleration case, had both solved the problems, such as gapless compress engagement between reduction box roller and cam；Solve again because of connection spiral shell
Nail and end cap protrude casing, cause reduction box to install the problem of inconvenience.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：One kind is without mode connects for screw and band eccentric adjusting
The worm-cam reduction box of mechanism, including casing 10, camshaft 4, cam 6, roller 11, taper roll bearing 2, O-shaped rubber are close
Seal 5, space collar 7, lip-type packing 9, wherein, taper roll bearing 2 is arranged on two axle journals of camshaft 4, and cam 6 is pacified
On camshaft 4, and engaged with the compression of roller 11, space collar 7 is arranged between camshaft 4 and the inner ring of taper roll bearing 2,
Setting-up eccentricity set 1 is coordinated using gap in the left and right sides bearing saddle bore of casing 10, eccentric bushing 1 it is cylindrical with boss,
Mounting and adjusting end cap 3 in left side eccentric bushing 1, the mounting and adjusting open end cap 8 in right side eccentric bushing 1, taper roll bearing 2 is installed
Between eccentric bushing 1 and two axle journals of camshaft 4, the outside table of adjustment end cap 3 and the not prominent casing 10 of adjustment open end cap 8
Face.
Preferably, coordinated using screw thread between eccentric bushing 1 and adjustment end cap 3 and adjustment open end cap 8 and coupled.
The beneficial effect that the present invention possesses：1. the axial location of cam and radial position can be adjusted simultaneously, is adjusted
End cap and the paired of adjustment open end cap use, and the taper roll bearing of mounted in pairs can be positioned and end-play is adjusted
It is whole, again can be overall to cam and taper roll bearing to be adjusted axially in the case where clearance requirement is met；By rotation
Eccentric bushing, the gap between removal roller and cam, reduces error indirectly, increases indexing accuracy.2. without mode connects for screw, knot is simplified
Structure, reduces number of parts, reduces cost；3. axially mounted space is saved.

Specific embodiment
Specific embodiment of the invention is described further below in conjunction with the accompanying drawings.
As shown in Fig. 1~2, a kind of worm-cam reduction box without mode connects for screw and with eccentric adjustable mechanism, including casing
10th, camshaft 4, cam 6, roller 11, taper roll bearing 2, O-shaped rubber seal 5, space collar 7, lip-type packing 9, its
In, taper roll bearing 2 is arranged on two axle journals of camshaft 4, and cam 6 is arranged on camshaft 4, and is compressed with roller 11
Engagement, space collar 7 is arranged between camshaft 4 and the inner ring of taper roll bearing 2, in the left and right sides bearing saddle bore of casing 10
Interference setting-up eccentricity set 1, eccentric bushing 1 it is cylindrical with boss, play axial limiting.Installed in eccentric bushing 1 in left side and adjusted
Whole end cap 3, the mounting and adjusting open end cap 8 in right side eccentric bushing 1, taper roll bearing 2 is arranged on eccentric bushing 1 and camshaft 4
Two axle journals between, adjustment end cap 3 and adjustment open end cap 8 protrude casing 10 outer surface.
Coordinated using screw thread between eccentric bushing 1 and adjustment end cap 3 and adjustment open end cap 8 and coupled, the circle of mounted in pairs
Taper roller bearing 2 is used to bear external load and locating shaft and cam, and two eccentric bushings 1 are used to support taper roll bearing, profit
With the hole rotating eccentricity set on eccentric bushing, while the radial position of adjustment axis 4 and cam 6, adjustment end cap 3 and adjustment open end cap
8 are used to fix the axial location of taper roll bearing, while adjusting the axial location of camshaft and cam.By adjusting cam
Radial position, makes cam press tightly against roller, eliminates gap, improves indexing accuracy.
By that using end cap and adjustment open end cap is adjusted, can be determined the taper roll bearing of mounted in pairs in pairs
Position and end-play adjustment, again can be overall to cam and taper roll bearing to enter axially in the case where clearance requirement is met
Row adjustment.By rotating adjustment end cap and adjustment open end cap, the fine thread using it between eccentric bushing axially enter
Move back, accurate adjustment can be carried out to the amount of feeding while sealing is ensured, it is ensured that the axial position of taper roll bearing clearance and cam
Put precision.By rotating eccentricity set, the gap between removal roller and cam, reduces error indirectly, increases indexing accuracy.
When eccentric bushing is adjusted, while frock is inserted in 2 holes of eccentric bushing, rotating eccentricity set, makes eccentric bushing together
Maximum eccentric location following change, and then change the gap of the radial position of axle and cam, adjustment cam and roller.In regulation
During eccentric bushing, 360 ° of offset can be back and forth adjusted, as long as rotating eccentricity set, you can while adjusting between cam and roller
Radial clearance, eliminates error.
The present invention is not limited to above-mentioned implementation method, in the ken that art those of ordinary skill possesses
It is interior, can also be made a variety of changes on the premise of present inventive concept and principle is not departed from.
