Description
Technical field
The utility model belongs to driving parts technical field, is related to a kind of gear, more particularly to a kind of backlash adjustment gear.
Background technology
Theoretically a pair of of gear in engagement should without sideshake, but in practice to compensation due to processing, installation error and
Change in size caused by temperature change, to prevent from being stuck, wheel coast side of tooth must there are certain backlash,
With the presence of sideshake, sideshake is used for preventing from making the gear teeth block due to error and thermal deformation gear drive, and gives the flank of tooth
Between lubricating oil film there are space, but sideshake brings idle running to mechanism in reversion again simultaneously, prevents mechanism from being accurately positioned, is
It reduces or eliminates the adverse effect that sideshake is brought to mechanism, needs to use backlash adjustment gear.
Current most common clearance elimination gear is that spring disappears gap by elastic original paper automatic compensation gap, is connected to using spring
Two plate gears together are engaged on coupling gear simultaneously, wherein a plate gear is fixed with axis, another plate gear is empty set in axis
On floating gear piece, when gear rotates, the gap between engaging tooth and working flank, by another of spring straining floating
Gear tooth is filled up.This structure be widely used in it is gear-driven disappear in gap, but by spring disappear gap there are it is long when
Between reduced using rear spring, the undesirable problem of the gap that disappears effect.
Invention content
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, provides a kind of manufacture simple in structure
Backlash adjustment gear at low cost and that the service life is longer.
The purpose of this utility model can be realized by following technical proposal：A kind of backlash adjustment gear, including phase interworking
The master gear and pinion of setting are closed, the master gear extends centrally out the axle sleeve to form integral structure, the pair tooth
The center of wheel offers axis hole and is sheathed on axle sleeve by axis hole clearance fit, which is characterized in that the master gear and secondary tooth
Circumferential and uniformly offer the identical screw hole one in several positions on the flank of tooth of wheel, the master gear and pinion pass through in spiral shell
Screwing bolts form one at hole one, and adjustable column is symmetrically arranged on the flank of tooth of the master gear, is opened up on the pinion
There is the through-hole passed through for adjustable column, being located at through-hole edge on the flank of tooth of the pinion has lug, the top of the adjustable column
End offers and the matched screw hole two of lug and has screwed screw rod in screw hole two.
The technique effect of this backlash adjustment gear is：Due to the gap width of transmission system middle gear, the whole of equipment can be influenced
Body positioning accuracy, so in the transmission system of equipment, it is necessary to eliminate this gap width, this backlash adjustment gear uses interlocking tooth method
Reduce backlash, so that gear drive positioning accuracy is improved, and reduce gear noise, gap is adjusted by twin-screw, is locked after adjustment
Tightly, prevent backlash from changing, axial restraint bolt forced locking after adjusting gap increases the stability of product, and backlash becomes larger mill
It can repeat to adjust after damage, it is simple in structure easy to adjust, it is cost-effective.
In a kind of above-mentioned backlash adjustment gear, the master gear is identical with the number of teeth of pinion.
In a kind of above-mentioned backlash adjustment gear, it is structure as a whole between the master gear and adjustable column, the pair
It is structure as a whole between gear and lug.
In a kind of above-mentioned backlash adjustment gear, the bolt is identical as the quantity of screw hole one and is four.
In a kind of above-mentioned backlash adjustment gear, gasket is arranged on the bolt.
Compared with prior art, this backlash adjustment gear adjusts gap by twin-screw, has by bolt strong fastening
Backlash is easy to adjust and can repeat to adjust the advantages of the service life is longer.
