Abstract
The utility model discloses a split type traction machine. At present, in a permanent magnet gear-free traction machine used at home, a traction sheave and a brake wheel are integrally formed or assembled into a whole; sound generated by friction brake comprises sound generated by ejecting off a brake by a spring; the sound is directly transmitted to the traction sheave; and the sound of the traction sheave is transmitted to a car through a steel wire rope, so that the comfortableness of customers taking the elevator is greatly influenced. The split type traction machine comprises an enclosure, a rotating shaft, a brake device and the traction sheave arranged on the rotating shaft. The split type traction machine is characterized in that the brake device comprises a brake wheel arranged at one end of the rotating shaft; and the traction sheave and the brake wheel are of a split type structure. The brake wheel and the traction sheave are separated and are respectively arranged on the shaft; and due to the adoption of the structure, the phenomenon that the noise generated by the brake system during the operation is transmitted to the car is avoided and further the comfortableness is improved.

As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Described brake equipment also comprises the drg that is fixed in casing, two brake control levers that are symmetrically set in the traction sheave periphery, be located at brake shoe seat on the brake control lever, be fixed in the inboard brake shoe of brake shoe seat; Described brake shoe seat is connected through the seat locating dowel pin with brake control lever; One end of brake control lever is connected with drg, and the other end of brake control lever is through bar locating dowel pin and casing switching.
Described drg comprise two can promote push rod that two brake control levers, one end moves outward, with the push rod parallel guide rod, described guide rod passes two brake control levers, socket can make the spring that moves in the brake control lever on the guide rod in the brake control lever outside.
Described brake shoe is fixed on the brake shoe seat through flathead screw.
Be provided with tack coat between described brake shoe seat and the brake shoe.Reinforcement brake shoe seat is connected with brake shoe.
Be respectively equipped with bearing in the rotating shaft of described traction sheave both sides, described bearing is supported on traction sheave on the casing through end cap, and the rotating shaft in the bearing outside is provided with described brake wheel.
Beneficial effect: brake wheel and traction sheave split, both are respectively installed on the axle, and the noise that this structure has been stopped to produce in the brake system operational process passes to car, has improved traveling comfort.
Description of drawings
Fig. 1 is the utility model master TV structure scheme drawing.
Fig. 2 is the utility model side-looking structural representation.
Among the figure: 1-casing, 2-rotating shaft, 3-traction sheave, 4-brake wheel, 5-drg, 6-brake control lever, 7-brake shoe seat, 8-brake shoe, 9-seat locating dowel pin, 10-bar locating dowel pin, 11-push rod, 12-guide rod, 13-spring.
The specific embodiment
Below in conjunction with Figure of description the technical scheme of the utility model is done further detailed description.
The utility model comprises casing 1, rotating shaft 2, brake equipment, is located at the traction sheave 3 in the rotating shaft 2, drg that brake equipment comprises the brake wheel 4 of being located at rotating shaft 2 one ends, be fixed in casing 15, two be symmetrically set in traction sheave 3 peripheries brake control lever 6, be located at brake shoe seat 7 on the brake control lever 6, be fixed in the inboard brake shoe 8 of brake shoe seat 7; Brake shoe seat 7 is connected through seat locating dowel pin 9 with brake control lever 6; One end of brake control lever 6 is connected with drg 5; The other end of brake control lever 6 is through bar locating dowel pin 10 and casing 1 switching; Drg 5 comprise two can promote push rod 11 that two brake control levers, 6 one ends move outward, with push rod 11 parallel guide rod 12; Guide rod 12 passes two brake control levers 6, and socket can make the spring 13 that moves in the brake control lever 6 on the guide rod 12 in brake control lever 6 outsides.Brake shoe 8 is fixed on the brake shoe seat 7 through flathead screw.For strengthening being connected of brake shoe 8 and brake shoe seat 7, between brake shoe seat 7 and brake shoe 8, be provided with tack coat.
For increasing the load ability of towing machine; Be respectively equipped with bearing in the rotating shaft 2 of traction sheave 3 both sides; Bearing is supported on traction sheave 3 on the casing 1 through end cap, and the rotating shaft 2 in the bearing outside is provided with brake wheel 4, and brake wheel 4 is installed in respectively on the different shaft parts of rotating shaft 2 with traction sheave 3; The noise transfer of effectively avoiding brake equipment is produced is given casing, improves the traveling comfort of taking.
During use, give the order of drg 5 energisings or outage through instruction.The thrust of drg 5 is on push rod 11 during energising, and brake control lever 6 push rods move outside 11 places; This power makes brake control lever 6 upper springs 13 make also outer moving by compression here simultaneously; Moving brake shoe seat 7 outer the moving of the outer shipper pole of brake control lever 6 make brake shoe 8 leave brake wheel 4 surfaces, and elevator normally moves.Drg 5 no thrusts during outage, the power on the spring 13 make the state before brake control lever 6 recovers energising, and the towing machine rotating speed drops near zero-speed, brake shoe 8 and brake wheel 4 cylindrical friction brakinges, and elevator stops.In above process; Flexible and the brake shoe 8 and brake wheel 4 contact frictions of drg 5 open closed, spring 13 all can be sounded; If brake wheel 4 will pass to car to top said sound through steel rope with traction sheave 3 one, influence the comfort of elevator, the present technique scheme is brake wheel 4 and traction sheave 3 splits; Both are respectively installed on the axle, stopped the noise that brake equipment produces and pass to car in operational process.
