Abstract
A variable-force damper for knotters comprises a knotter shaft, an eccentric friction plate, an elastic friction unit and a housing; the elastic friction unit comprises a left press plate, a left friction plate, a right friction plate, a right press plate, rivets, bolts, nuts, washers and springs; the housing comprises a support and guide rods; the eccentric friction plate and the knotter shaft are connected together and mounted on the housing together; the elastic friction unit is connected with the guide rods, and both sides of the eccentric friction plate are respectively superposed with the left friction plate and the right friction plate. The variable-force damper for the knitters is characterized in that: since the axis and the outer circle of the eccentric friction plate are not concentric, as the eccentric friction plate is rotated once, the contact areas between both sides of the eccentric friction plate as well as the left and the right friction plates are respectively periodically changed. The variable-force damper for the knitters, which is provided by the invention, has the characteristics of low-damp starting and high-damp braking.
Description
Technical field
The invention belongs to the agricultural machinery application, knotter is the vitals of herbage and agricultural crop straw picking up and bundling machine, and the present invention is specifically related to a kind of knotter variable force damping unit, is made up of knotter shaft, eccentric friction plate, elastic-friction device, support; The present invention provides the variable force damping unit of a kind of little damping startup, big damping brake.
Background technology
In existing technology, the damping unit resistance is constant during knotter work; Knotter shaft rotates a circle knotter work once; In order to guarantee the knotter even running; Knotter shaft must be installed damping unit, and the excessive knotter shaft of damping starts difficulty, brake fade when stopping that damping is too small; The present invention provides the variable force damping unit of a kind of little damping startup, big damping brake, can guarantee the knotter reliably working effectively.
Summary of the invention
The object of the invention is to provide a kind of knotter variable force damping unit.
The present invention realizes through following technical scheme:
A kind of knotter variable force damping unit is made up of knotter shaft, eccentric friction plate, elastic-friction device, support; The elastic-friction device is made up of left pressing plate, left friction plate, right friction plate, right pressing plate, rivet, bolt, nut, pad, spring; Support is made up of bearing, guide rod; Eccentric friction plate connects with knotter shaft and is rack-mount; The elastic-friction device connects with guide rod, and eccentric friction plate two sides overlap with left friction plate and right friction plate rubbing surface respectively.
Knotter variable force damping unit is characterised in that eccentric friction plate axle center and cylindrical decentraction, and eccentric friction plate rotates a circle, eccentric friction plate two sides respectively with the contact area cyclically-varying of left friction plate and right friction plate.

Embodiment
According to accompanying drawing the present invention is done further description:
A kind of knotter variable force damping unit is made up of knotter shaft (1), eccentric friction plate (2), elastic-friction device (3), support (4); Elastic-friction device (3) is made up of left pressing plate (5), left friction plate (6), right friction plate (7), right pressing plate (8), rivet (9), bolt (10), nut (11), pad (12), spring (13); Support (4) is made up of bearing (14), guide rod (15); Eccentric friction plate (2) connects with knotter shaft (1) and is installed on the support (4); Elastic-friction device (3) connects with guide rod (15), and eccentric friction plate (2) two sides overlap with left friction plate (6) and right friction plate (7) rubbing surface respectively.
Knotter variable force damping unit is characterized in that eccentric friction plate (2) axle center and cylindrical decentraction, and eccentric friction plate (2) rotates a circle, eccentric friction plate (2) two sides respectively with left friction plate (6) and right friction plate (7) contact area cyclically-varying.So the damping that knotter shaft (1) is produced also changes.
During work; Eccentric friction plate (2) two sides overlap with left friction plate (6) and right friction plate (7) rubbing surface respectively; Knotter shaft (1) drives eccentric friction plate (2) rotation, and left friction plate (6) and right friction plate (7) produce friction to eccentric friction plate (2) knotter shaft (1) is produced damping action under the pressure effect of spring.Because eccentric friction plate (2) axle center and cylindrical decentraction, eccentric friction plate (2) rotates a circle and left friction plate (6) and the variation of right friction plate (7) contact area generating period property, and the damping that like this knotter shaft (1) is produced also changes.Thereby can realize that the little damping of knotter shaft starts, the effect of big damping brake, can guarantee the knotter reliably working effectively.
