Abstract
An anti-backlash gear. Relates to an anti-backlash gear. The eccentric shaft comprises an eccentric head, a shaft body and a square head, wherein the eccentric head is movably arranged in the kidney-shaped groove, the shaft body is movably connected with the through hole B corresponding to the pinion, the square head extends out of the through hole B corresponding to the through hole A, and the fastening piece penetrates through the through hole A in the pinion to be connected with the threaded hole in the main gear. The utility model discloses it is effectual to eliminate the crack, and operation adjustment is convenient.
Description
Technical field
The utility model relates to a kind of clearance elimination gear.
Background technique
In the gear transmission, between meshed gears certain clearance can appear, along with the growth of service time, and the profile of tooth wearing and tearing, the gap of gear can increase gradually between engagement.In the machinery with precision drive requirement, this gap can have a strong impact on the precision of equipment operation.
The model utility content
The utility model provides a kind of clearance elimination gear of the gap between the meshed gears of crack of disappearing at above problem.
The technical solution of the utility model is: comprise master gear, also comprise pinion, eccentric shaft and fastening piece, pinion has identical tooth proportions with master gear, on end face of master gear, be provided with the some tapped holes that are distributed in same circumference, on this circumference, also be provided with a kidney slot, kidney slot is radially laid on described end face, corresponding described tapped hole and kidney slot are provided with through hole A on the described pinion, through hole B, described eccentric shaft comprises eccentric head, axis body, square toes, eccentric head is movably arranged in the kidney slot, through hole B corresponding on axis body and the pinion flexibly connects, square toes stretch out corresponding through hole B, and the through hole A that described fastening piece passes on the pinion links to each other with tapped hole on the master gear.
Clearance elimination gear of the present utility model is made of major-minor gear arranged side by side, is provided with an eccentric shaft between two gears.When the major-minor gear and and its meshed gears between when having the gap, reverse the square toes of eccentric shaft, make pinion with respect to the master gear backward rotation, be equivalent to enlarge the tooth proportions of clearance elimination gear, by fastening piece that both are fixedly connected immediately then.So just eliminated the gap.The utility model crack that disappears is effective, operates easy to adjust.
