(2) liquid viscosity soft starting device.It is the soft starting device that a kind of shearing force of utilizing oil film is come carry-over moment; mainly contain active friction plate and form from movable friction plate; it has advantages such as flexible transmission, stepless speed regulation, overload protection equally; and its velocity ratio can reach 1, but its very high to the requirement of hydraulic oil and lubricant oil.It need be installed in the volume that has increased drive unit between prime mover and the retarder virtually.
Summary of the invention
In order to solve drive unit power loss, big, the bulky problem of heating value, the purpose of this utility model provides a kind of retarder that has the sticking clutch of liquid that plays buffering and reduce percussion in heavy mechanical equipment.
The technical solution of the utility model is the partition wall of fixing belt bearing saddle bore in the casing at retarder, and described partition wall is divided into one-level speed change space and two stage speed change space with box house; Input shaft and jack shaft are installed in the bearing saddle bore in one-level speed change space, input shaft comprises one-level deceleration driving gear and input axis body, jack shaft inserts one-level deceleration driven gear and uses flat key to be linked together, and the one-level deceleration driving gear is meshed with one-level deceleration driven gear; In bottom, two stage speed change space sun wheel shaft is set, sun wheel shaft connects by gear coupling with jack shaft, described sun wheel shaft comprises sun gear axis body and sun gear, sun gear is meshed with planet wheel, planet wheel also meshes with gear ring, at gear ring movable friction plate is arranged fixedly, the below of movable friction plate arranges the static friction sheet, and the static friction sheet is fixed on the casing.Planet wheel comprises planet wheel body, planet wheel shaft and output shaft.One end of sun wheel shaft is connected with jack shaft, and the other end is fixed on the sun gear.
When moving under the promotion of control piston in hydraulic system, the joint of control movable friction plate and static friction sheet is controlled the motion of gear ring, and then the transmission of control input shaft and output shaft.
The beneficial effects of the utility model are that retarder and soft start are combined as a whole, and work in same casing, reduce volume, save the space, and working principle is simple, the transmission efficiency height, and slip is little, can satisfy the needs of heavy mechanical equipment.
