Description
Technical field
The present invention relates to a kind of handwheels, are specifically designed a kind of precision machinery hand used in fine adjustment or measurement process
Wheel.Belong to accurate mechanical equipment manufacturing technology field.
Background technique
General The gear deceleration needs multistage；Volume difficulty is small again for differential soft tooth transmission, and Gu Te labors the design of needle tooth speed reducing hand wheel.
To reduce " equal power " mechanism is specially designed to the friction of pinwheel again, to reduce abrasion, prolonged the service life.Many years are manufactured experimently real
Gradually improvement, it was demonstrated that the present invention is rationally perfect.
Summary of the invention
The object of the present invention is to provide a kind of needle teeth (same main shaft) living and can thickness tune handwheel.
The present invention mainly by fixed bearing A, B wheel, fine tuning handwheel C, movable post gear E, jam plate D, fine motion axle sleeve J, main shaft M,
Two-way clutch is swollen spring K, coarse adjustment handwheel N is constituted, and B wheel includes needle G, equal power ring L living, and movable post gear E includes movable post H, main shaft M with
Coarse adjustment handwheel N, two-way clutch is swollen, and spring K is connected, and movable post wheel E is locked on fine motion axle sleeve J through jam plate D, and fine motion axle sleeve J is through double
Main shaft M is transmitted in the swollen spring K of clutch.
By the swollen spring K of two-way clutch, main shaft M is separated with fine motion axle sleeve J when coarse adjustment handwheel N is adjusted, when fine tuning handwheel C is adjusted
Main shaft M closes fine motion axle sleeve J through swollen spring K.
Fine tuning handwheel C is with a thickness of 15mm, the eccentric hoop interplanting of each needle G living in diameter 50mm, B wheel in fine tuning handwheel C
It will be sequentially inserted into movable post gear E (can micro- rotation) gap movable post H with lower, when fine tuning handwheel C turn one is enclosed, movable post tooth
The mobile movable post of E is taken turns, then 16 circle movable post gear E rotation of fine tuning handwheel C rotation, one circle.
Coarse adjustment handwheel N is with a thickness of 10mm, diameter 15mm.
When in each needle G living insertion gap movable post H in B wheel equal power ring L will be inserted into each needle G living in opposite of seam outwardly against
The eccentric strap of fine tuning handwheel C, without causing the needle point of needle G living to scratch movable post H.
The quantity of movable post H is n=16, and needle G quantity living is n+1=17, and not limiting n can use other values.
Advantages of the present invention:
" needle tooth speed reducing hand wheel living " is devised in precision machinery is adjusted to minimize, handwheel；After manufacturing experimently and trying out,
Group's linkage " equal power ring " is increased on n+1 needle living again, so that movable post will not be scratched.Using effect is favourable, and the service life is big
To increase.Again for that can realize thickness tune without generating difference gap in same main shaft, positive and negative two have been redesigned to equal energy " clutch "
" swollen spring " mechanism, so that thickness (speed) tune is extremely convenient on demand.
Detailed description of the invention
Fig. 1 needle tooth (same main shaft) living is simultaneous can thickness tune handwheel schematic diagram.
The fixed support of A, B wheel, needle G, fine tuning handwheel C, movable post gear E living, movable post H, equal power ring L, jam plate D, fine motion axle sleeve
J, two-way clutch is swollen spring K, main shaft M, coarse adjustment handwheel N, dust-proof transparent panel I (and motion state of observable L, G) are fixed on main shaft M
Position axle sleeve (and locking lid on trimming hand wheel) F.
Fig. 2 is the a-a radial cross-section of Fig. 1
Specific embodiment
The present invention is described further with reference to the accompanying drawing.
Scheming (1) is overall structure along main shaft sectional view (only having drawn cut-away section line)；Scheme the a-a radial direction section view that (2) are Fig. 1
Scheme (non-cross-hatching).It is as follows by scheming its operating principle known to (2):
1. B is taken turns Zhi Ding by fixed bearing A.Each needle G living in B wheel will be sequentially inserted under the eccentric strap effect of handwheel C
In movable post gear E (can micro- rotation) gap movable post H (while power ring L will be inserted into opposite each needle living of seam outwardly against bias
Ring, without causing the needle point of G to scratch movable post H), when C turn one is enclosed, the mobile cylinder of movable post wheel E, then handwheel C rotation 16
Circle, one circle of movable post wheel E rotation.Since movable post wheel E is locked on fine motion axle sleeve J through jam plate D, then fine motion axle sleeve is driven through swollen spring K
In main shaft M, M is made also to rotate with it a circle, realizes 1: 16 fine tuning deceleration.
But it is too slow long to dislike trimming hand wheel to adjust (especially in adjustment process) again sometimes, and needs quickly to be transferred to predetermined value attached
Closely, therefore devise " two-way clutch is swollen spring " mechanism again so that when needed can directly turn main shaft thick (fast) tuning knob N without
Slow down.No matter coarse adjustment button N is dextrorotation or derotation to the design, and swollen spring K can all be made " to leave " fine motion axle sleeve J and rotate freely；When only
Fine motion handwheel C is adjusted when uncomfortable coarse adjustment button N, " two-way clutch is swollen spring " makes fine motion wheel case J " close " main shaft at swollen spring again
M, so that main shaft M fine motion with fine motion axle sleeve J, reaches deceleration purpose.The upper end locking closure F of fine motion handwheel C becomes the upper end main shaft M
Positioning shaft sleeve has transparent dust-proof plate I (also serving as L, G motion state peep hole) under driving hole.It is on probation through manufacturing experimently, as long as processing
Technique reaches requirement, and using effect is fine.
2. the top and bottom of two-way clutch is swollen spring K are close to hooking in the corresponding aperture of main shaft M, when directly using consolidating
When being connected in the coarse adjustment button N dextrorotation of main shaft, hole is still hooked on K spring, and K is driven to embrace to M, and then pine stretches in lower opening end hook under K, real
Existing " pine from " fine motion covers J, and eccentric bushing C locks E by each needle (the work needle being especially inserted into) living and takes turns when fine motion handwheel is not turned
Each column is without fine motion, therefore the free dextrorotation of main shaft M；When coarse adjustment button N is left-handed, K spring lower end is still hooked, and dragging K is embraced to rise to the bait to M, K
Then pine stretches in hole, " pine from " fine motion set J and it is freely left-handed.Therefore mechanism realizes same main shaft and can thickness tune.
3. how elastic force ring L realizes " equal power "? there is endless groove on each needle G living, the periphery of elastic force ring L is close to each needle
Needle bullet outer circumferential side living can also be made the ball cap end of needle living close to eccentric bushing C, to reduce each needle point pair living by the outside of annular groove
The pressure of each cylinder H of movable post wheel, plays the role of equal power.The especially consistency of each needle and B wheel, E wheel point in processing and manufacturing
The accuracy error of degree can all be such that pressure between each needle column differs, and equal power ring L can then play the role of " equal power ", reduce each work
Frictional force between needle and movable post and can prolong the service life.
