Summary of the invention
The object of the invention is for above-mentioned situation, a kind of novel sphere pendulous device is provided, to break through the restriction to more than 800 tons of pressure stages large-scale rotary forging press.
Object of the present invention is realized by following technical proposals: a kind of sphere pendulous device for large-scale rotary forging press, comprise holder and be fixed on driving gearbox and the oil motor at its top, drift angle sleeve system in holder is fixedly connected with terminal pad by driving long key with described driving gearbox, described drift angle cover axial center is oscillating spindle, oscillating spindle lower end is bulb and yaw, and realize being rotationally connected by the cooperation of bulb and ball bowl, described ball bowl surface is arranged one deck high molecular abrasion-proof layer, and this ball bowl is also arranged a fuel feed hole from outside the contact surface through to bulb and ball bowl, enclose contact position at ball bowl bottom along ball bowl and bulb one and be fixedly connected with the oil collector being with cannelure by screw.
As preferred embodiment, described high molecular abrasion-proof layer is embedded on ball bowl.
As preferred embodiment, described oil collector exterior bottom offers outage.
As preferred embodiment, described oscillating spindle is Steel material, and described ball bowl is high-grade nodular cast iron, and described high molecular abrasion-proof layer is high molecular abrasion-proof material.The embedded nodular cast iron balls bowl of high molecular abrasion-proof material replaces acid bronze alloy ball bowl, can reduce manufacturing cost and maintain and replace cost.
As preferred embodiment, hydraulic oil motor is adopted to drive as power-actuated oil motor.The mode that hydraulic oil motor drives can realize the driving of remote power.
Beneficial effect of the present invention is as follows:
1, sleeve cording in drift angle is for floating compensation function, can realize the clearance automatic compensation after the small wearing and tearing of spherical pair;
2, on ball bowl body, arrange fuel feed hole as forced feed lubrication cooling oil duct, make its coefficient of sliding friction be reduced to 0.01-0.02 from 0.1-0.15, the frictional force on friction pair contact surface reduces greatly, and ensure that large-tonnage rotary forging press reliability of operation.
