Abstract
The utility model relates to a gear mechanism with adjustable center distance, which comprises a driving wheel, a driven wheel and a distance adjusting gear assembly, wherein coaxial gear structures are arranged on the driving wheel and the driven wheel, and the distance adjusting gear assembly comprises a connecting crank arm, a gear mounting plate and two distance adjusting gears; the gear mounting plate is arranged on the connecting crank arm, two ends of the gear mounting plate are respectively provided with one distance adjusting gear, the two distance adjusting gears are meshed with each other, one of the distance adjusting gears is meshed with the gear on the driving wheel, and the other distance adjusting gear is meshed with the gear on the driven wheel; after the relative height or the interval of the driving wheel and the driven wheel are adjusted, the gear mounting plate can be rotated, so that the two distance adjusting gears can rotate within a certain range, and the adjusted driving wheel and the adjusted driven wheel are continuously matched, so that the requirements of plate polishing and brushing of different thicknesses are met.
Description
Technical Field
The utility model relates to a gear mechanism of adjustable centre-to-centre spacing.
Background
An upper roller back pressing wheel of the existing grinding and brushing machine is a fixed roller and cannot be adjusted up and down; a driven wheel gear is arranged on the upper roller, a driving wheel gear is arranged on the lower roller, and the driving wheel gear and the driven wheel gear are meshed through an idle wheel group consisting of two gears to carry out roller transmission; the central distance of the gear transmission device cannot be automatically adjusted, and the roller cannot be adjusted in height up and down; the requirements of the plate grinding and brushing with different thicknesses can not be met.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a gear mechanism of adjustable centre-to-centre spacing in order to overcome prior art not enough.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a gear mechanism with adjustable center distance comprises a driving wheel, a driven wheel and a distance adjusting gear assembly, wherein coaxial gear structures are arranged on the driving wheel and the driven wheel, and the distance adjusting gear assembly comprises a connecting crank arm, a gear mounting plate and two distance adjusting gears; the gear mounting plate is arranged on the connecting crank arm, two ends of the gear mounting plate are respectively provided with a distance adjusting gear, the two distance adjusting gears are meshed with each other, one of the distance adjusting gears is meshed with the gear on the driving wheel, and the other distance adjusting gear is meshed with the gear on the driven wheel.
Preferably, the connecting crank arm is L-shaped.
Preferably, the connecting crank arm is fixed, and the gear mounting plate is rotatably arranged on the connecting crank arm and matched with the connecting crank arm through a shaft pin.
Preferably, the gear mounting plate and the connecting crank arm are relatively fixed, and the connecting crank arm can rotate along the connecting part of the gear mounting plate and the connecting crank arm.
Preferably, the two pitch gears have the same structure.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the utility model discloses the gear mechanism of adjustable centre-to-centre spacing of scheme, after adjustment action wheel and the relative height or the interval from the driving wheel, rotatable gear mounting panel makes two roll adjustment gears at certain limit internal rotation, continues to match the action wheel after adjusting and from the driving wheel to satisfy the panel scrubbing requirement of different thickness.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a schematic diagram of a gear mechanism with adjustable center distance according to the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the gear mechanism with adjustable center distance of the present invention comprises a driving wheel 1, a driven wheel 2 and a distance adjusting gear assembly, wherein the driving wheel 1 and the driven wheel 2 are both provided with coaxial gear structures, and the distance adjusting gear assembly comprises a connecting crank arm 3, a gear mounting plate 4 and two distance adjusting gears 5; the gear mounting plate 4 is arranged on the connecting crank arm 3, two ends of the gear mounting plate 4 are respectively provided with one distance adjusting gear 5, the two distance adjusting gears 5 are identical in structure and meshed with each other, one of the distance adjusting gears 5 is meshed with a gear on the driving wheel 1, and the other distance adjusting gear 5 is meshed with a gear on the driven wheel 2.
The distance-adjusting gear assembly has two rotation modes, one mode is that the connecting crank arm 3 is fixed, the center of the gear mounting plate 4 is rotatably arranged on the connecting crank arm 3 and is matched through a shaft pin, and the gear mounting plate 4 is locked when in work; when the adjustment is needed, the shaft pin is loosened, and the gear mounting plate 4 can be rotated, so that the distance adjustment is carried out.
The other method is that the gear mounting plate 4 and the connecting crank arm 3 are relatively fixed, the connecting crank arm 3 is L-shaped, and the connecting crank arm 3 can drive the gear mounting plate 4 to rotate along the connecting part of the gear mounting plate 4 and the connecting crank arm 3, so that the distance adjustment is carried out.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
