Abstract
The utility model provides a rivetless braking block, which is a member of a braking device. The friction belt material in the braking block and the fixed mode of the friction belt and a horseshoe are changed. The friction belt is pressed and is fixed on an arc surface of the horseshoe through a screw hole, a press plate, a washer, a screw bolt, etc., on the surface of both ends of the horseshoe. The brake block of the structural mode has the advantages that a braking wheel is not damaged, maintenance and repair are convenient, etc., and the service life can be improved more than one time.
Description
The utility model belongs to a kind of mechanical brake equipment parts.
Break is the important component part of metallurgical, mine mechanism and materials handling equipment, and the braking that relies on its to realize equipment stops and slowing down.Present break commonly used, means of fixation between the shoes of its brake shoe and the friction band, traditional practice is will rub to be with several rivets to be fixed on the shoes both at home and abroad.Facts have proved that there is following drawback in the brake shoe of this kind means of fixation.
1, the abrasion through after a while is with in friction, and rivet head exposes, and very easily scratches the Brake drum surface, makes it to form scraggly big minor groove, reduces the working life of equipment braking effect and Brake drum; 2, install, dismantle, overhaul difficulty, influence equipment operation rate; 3, cost of overhaul height and labor strength are big.
The purpose of this utility model is at above-mentioned drawback, and a kind of no rivet brake shoe that provides is by material and the measures such as means of fixation of friction band with shoes that changes its friction band, to remedy above-mentioned deficiency.
The purpose of this utility model is achieved in that with the planing of shoes both ends of the surface and is drilled to screw that screw quantity is relevant with the friction bandwidth.Two of manufacturing and shoes end face aperture, the pressing plate that pitch-row is identical, the width of pressing plate is decided on the thickness of friction band, be advisable with 1/2nd places that push down the friction tape thickness, the chord length of friction band should be slightly larger than the chord length of shoes, be equipped with corresponding packing ring, bolt etc., the friction band tightly can be fixed on the shoes by lock bolt, pressing plate.For raising compresses effect and wear resistance, the material of friction band can be selected the high asbestos-phenolic resin of intensity or some intensity other material good than high wear resistance for use, replaces original asbestos rubber friction band.Certainly, the brake shoe of this mode of structure, its geometrical shape can be various.
Below in conjunction with description of drawings structure of the present utility model once and means of fixation.
Fig. 1 is a plan view of the present utility model.
As shown in the figure, shoes 1, friction be with 2, pressing plate 3, packing ring 4, bolt 5.The arc friction is put on the cambered surface of shoes 1 with 2, because harness is wiped the chord length that is slightly larger than shoes 1 with 2 chord length, and rub and be with 2 to have certain resistance to flexure again, so friction can be with 2 tightly to be fixed on shoes 1 cambered surface by lock bolt 5, packing ring 4, pressing plate 3.
Technological scheme after the enforcement has changed the material of former friction band and traditional means of fixation, becomes no rivet compression type, has overcome thus because of rivet exposes the phenomenon of damaging the Brake drum surface, has improved the equipment braking effect, has prolonged the working life of Brake drum; In addition, easy installation and removal, once the time changed only is original 1/10th, has improved equipment operation rate, and has reduced operator's labor intensity.
The utility model is simple in structure, and is easily manufactured, and effect is obvious, and be enhanced about more than once working life.
Claims (1)
1, no rivet brake shoe, form by shoes (1), friction band (2), it is characterized in that, arc friction band (2) is put on the cambered surface of shoes (1), and the friction band (2) of chord length that will be slightly larger than shoes (1) by the bolt (5) on shoes (1) both ends of the surface, packing ring (4), pressing plate (3) is fixedly on the cambered surface of shoes (1).
