Embodiment
A kind of wind power generating set high speed shaft break; Comprise caliper pedestal 1, by moving caliper 2 and caliper 3 initiatively; Described caliper pedestal 1 is made up of the directional post 4 that spectacle base and two is parallel to each other; By moving caliper 2 is seat shape; Be provided with passive brake block 6 by the seat support of moving caliper 2, on the seat support of the left and right sides of passive brake block 6, be provided with passive brake block link stopper 7, be provided with connection by the moving caliper 2 and the following bolt hole 14 of caliper 3 initiatively by the chair back of moving caliper 2; Be set with guide pipe 5 respectively by the right ends of the chair back of moving caliper 2 back; Initiatively caliper 3 be the T font, the T font initiatively the afterbody of caliper 3 be provided with bolt hole 22, in the head of T font active caliper 3, be provided with oil cylinder 20; Piston 21 in the oil cylinder 20 stretches out downwards; The pistons end that stretches out is fixedly connected with initiatively brake block 8, is provided with the pouring orifice 10 of oil cylinder 20 in the side of T font active caliper 3, and connecting bolt 9 will be fixed together by moving caliper 2 and active caliper 3 through last bolt hole 22 and following bolt hole 14; What link together is actively socketed on two directional posts 4 of caliper pedestal 1 by moving caliper 2 and active caliper 3 through guide pipe 5; Be provided with the brake disc 19 of wind power generating set high speed shaft at the active brake block 8 of active caliper 3 and between, initiatively be provided with initiatively brake block Returnning spring 11 between the head of caliper 3, be provided with the caliper attachment post 15 that resets by the afterbody of moving caliper 2 at active brake block 8 and T font by the passive brake block 6 of moving caliper 2; Caliper pedestal 1 is provided with the caliper base 16 that resets by the spectacle base, resets and is provided with caliper Returnning spring 17 between the base 16 at reset attachment post 15 and caliper of caliper.
Top at the directional post 4 of caliper pedestal 1 is provided with directional post gland 18, on active caliper 3, is respectively arranged with the oil pressure monitoring sensor 13 of brake block abrasion detection sensor 12 and oil cylinder 20.
Break of the present invention is in working procedure; At first the sealing plug in the pouring orifice 10 is taken out, connect break design oil pressure, after pressure oil gets into the oil pocket of oil cylinder 20; Promoting piston 21 outwards moves; Thereby the upper surface contact friction of promotion active brake block 8 and brake disc 19 contacts with brake disc 19 simultaneously at active brake block 8, and brake disc 19 is given reaction force of oil of oil cylinder 20 through active brake block 8 and piston 21; This reaction force is transmitted to oil cylinder 20 upper walls; Thereby what promote to be fixed together is moved upward along the directional post 4 that two on the caliper pedestal 1 is parallel to each other by moving caliper 2 and active caliper 3 integral body, finally drives the lower surface friction of passive brake block 6 and brake disc 19, produces braking action.When declutching, only need release the oil pressure in the oil cylinder 20, active brake block Returnning spring 11 will drive active brake block 8 and reset, and caliper Returnning spring 17 drives whole caliper and resets, and reaches and moves back the effect impartial apart from the gap.
This break project organization, major advantage is: the loading, unloading brake block is very convenient, only need lay down block fastening screw trip bolt, brake block resetting means and block, brake block is transferred to change to install get final product; Reaction time is short, generally is not more than 0.3 second, and declutching, it is quick to reset; Intelligent brake block wearing and tearing and the temperature of detecting; The braking moment adjustable extent is big, long service life, and easy maintenance has avoided changing repeatedly machine product, and maintenance cost is low.
The superiority and inferiority and the braking moment of high speed shaft break braking effect have direct relation, and braking moment is main relevant with Properties of Friction Materials, oil pressure size, therefore as long as assurance oil pressure, seal ring, Properties of Friction Materials are stablized and just can be guaranteed the superior of braking effect.Between the general 0-16Mpa of this break design work oil pressure; Organic composite friction material dynamic friction coefficient 0.4, static friction coefficient 0.35-0.45, maximum service pressure 4N/mm
2, operating temperature is not more than 250 ℃; Sintered friction material dynamic friction coefficient 0.35 ± 0.05, static friction coefficient 0.35-0.4, maximum service pressure 4N/mm
