Abstract
The invention provides a brake technical proposal with a water-cooled friction plate structure, which comprises a stator bearing shell with internal gears, a water-cooled static friction plate with external gears meshed in the stator bearing shell with internal gears and a brake wheel which is provided with external gears and assembled on the end of a rotating shaft; the external gears of the brake wheel are meshed in a kinetic friction plate with internal gears to form a revolving solid of a rotor; the kinetic friction plate and the static friction plate are overlaid in the axial direction to form a plurality of friction pairs and form a brake torque under the effect of the thrust force of a hydraulic cylinder piston. A brake torque is formed under the effect of the hydraulic cylinder. Contrarily, when the hydraulic cylinder loses pressure, a separate dish spring set rebounds; the piston returns; the separate dish spring set actuates the kinetic friction plate and the static friction plate to form gaps; the brake torque disappears. The description belongs to a normal open type brake; if a single-action hydraulic cylinder is displaced for a normal close type hydraulic cylinder with dish spring energy storage; the whole normal open type brake becomes the normal close type brake.
Description
Technical field:
What the present invention relates to is break, especially a kind of break that is suitable for the large braking moment of mine down-hole use.Structurally can adapt to chemical industry, working in mine under the environment that has explosive gas coal dust, has the function of flame proof.
Background technique:
In the prior art, Patent Office of known technology Shi You State Intellectual Property Office has authorized disclosed 2007200227947; No. 2007100160119 patents.This binomial patent discloses a kind of disk type braker, this scheme is in the measure of the inner employing of brake disc recirculated water cooling, while making to brake, the heat producing on brake disc, by circulating water, replaced, can make the temperature of brake disc can be not too high, thereby can make disk type braker be applied to have under the working environment of requirement of explosion proof, but its friction pair be all two of brake disc.The in the situation that of braking moment 50～160KN.m, disk track design is at Φ 2000～Φ 2500mm, bulky, at down-hole, use and sometimes have narrow limitation, must develop small volume for this reason, be suitable for bank working surface, the break that the flight conveyer of bank crossheading and the soft start of belt conveyer speed change are used.
Summary of the invention:
Object of the present invention designs exactly has constituent, universe formula friction plate structure, and braking moment is break open in usual and the normally closed brake that 50～160KN.m controls.
This programme is achieved by the following technical measures, and comprises the stator support housing with internal tooth, has the water-cooled static friction sheet of external tooth, and its external tooth is engaged on the stator support housing with internal tooth; The Brake drum with external tooth, be assemblied in running shaft end, its external tooth is engaged on the movable friction plate with internal tooth, forms the solid of rotation of rotor, movable friction plate and static friction sheet are in axial stack, form a plurality of friction pairs, and under the thrust of hydraulic cylinder piston, form braking moment, its braking moment is: the positive pressure that piston produces, friction pair quantity, braking radius, the product of friction factor.
This programme is realized by following technical measures: comprise the stator supporting base housing with internal tooth, its internal tooth and multi-disc have the water-cooled static friction sheet engagement of external tooth, the disc type end cap of its assembling single-action hydraulic cylinder location, end; The disc type end cap of hollow water-cooled pressure-bearing is assembled in its other end, forms the ring casing static part that bears moment of torsion.The braking gear teeth portion with external tooth, the movable friction plate with multi-disc with internal tooth meshes, and forms the solid of rotation being braked.The number of combinations of friction pair as requested braking moment size and change.The disc type end cap center portion of oil hydraulic cylinder location and the end cap center portion of hollow water-cooled pressure-bearing be running in bearings all, and bearing bore diameter is positioned at running shaft end, is positioned on same axis.
When a plurality of single-action hydraulic cylinders are sent into oil pressure, the separated dish spring of piston compression group, friction pair forms braking moment, on the contrary during oil hydraulic cylinder decompression, separated dish spring group bounce-back, backward stroke of the piston, separated dish spring group impels sound friction plate to form gap, and braking moment disappears.Constituent has total water supply hose, total backwater flexible pipe, and a plurality of tap water supply hoses, are all helix-deformed structure, adapt to the working method of friction plate axial displacement.The water-cooled static friction sheet with external tooth, its heart portion is annular hollow body, manufactures out annular hollow body.
Foregoing description belongs to break open in usual, if single-action hydraulic cylinder is replaced into the normal closed hydraulic cylinder with the accumulation of energy of dish spring, whole break open in usual, become normally closed brake, oil hydraulic cylinder pressurization pressure oil, braking moment disappears, pressure oil disappears, and braking moment produces.Each oil hydraulic cylinder feed flow is to be taken over and connected by annular pressure oil content.
Hydraulic system is comprised of conventional hydraulic station, and electro-hydraulic proportional valve has been sent in the change of its oil pressure, and PLC computer system forms, and because the controllability of oil pressure just can be implemented the controllability of braking moment, guarantees acceleration and the retardation of work mechanism.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to having the water-cooled static friction sheet of external tooth, obtain good water circulation, the heat producing in friction pair work, derives rapidly, solve heating, the spark of break, and set up the reliability of friction original paper; Friction element is all enclosed in to form and bears in the annular casing static part of moment of torsion, just can design according to the NBS of explosion-proof casing design, reach the requirement of explosion-proof type break, be applied to use in the industries such as chemical industry, coal, oil, as can be seen here, the present invention compared with prior art, has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
