Abstract
The utility model relates to a friction hydraulic brake, which comprises a main shaft, a casing body, a bearing support, a bearing, inner friction plates, outer friction plates, a compression spring, pistons, an oil seal seat and an intermediate connection disk. The main shaft is supported on the bearing support through the bearing; a plurality of the inner friction plates and the pistons are sequentially arranged along the direction of a shaft end; the plurality of the inner friction plates are equally spaced and placed on the main shaft; piston cavities and a plurality of the outer friction plates are arranged on the inner side of the casing body at the positions corresponding to the pistons and the inner friction plates; the number and the spacing of the outer friction plates are similar to those of the inner friction plates; the inner friction plates and the outer friction plates are arrayed axially at intervals; the compression spring is placed among the intermediate connection disk and the pistons; and the compression spring enables one end surface of each piston to be tightly abutted to each friction plate when the piston cavities are in the state of having no hydraulic pressure oil, thereby enabling the inner friction plates and the outer friction plates to be combined. The friction hydraulic brake has the advantages of fine braking performance, long service life, convenient and flexible operation, simple structure, convenient maintenance, low cost and capabilities of realizing serialized and standardized design for products and facilitating popularization and application.
Description
Technical field
The utility model relates to break, relates in particular to the friction type hydraulic brake.
Background technique
Existing Hoisting Machinery is the braking torque that reaches higher, need add a cover braking device.This braking device is made up of more part, and cost is higher and take sizable space, makes installation, maintenance and uses all quite inconvenience.And the environment that this break uses is generally comparatively abominable, and this increases the maintenance frequency, each maintenance since its take up room greatly, component make that to remove and install workload big, the maintenance cost height more.
Summary of the invention
The purpose of this utility model is to overcome the drawback of above-mentioned prior art, and provide a kind of simple in structure, braking moment is big, volume is little, long service life, friction type hydraulic brake easy to maintenance.It is realized by following technological scheme:
Comprise main shaft, housing, bearing support, bearing, interior friction plate, outside friction disc, pressure spring, piston, oil sealing base and middle land, main shaft is bearing on the bearing support by bearing, oil sealing base is sealed on bearing support and is equipped with on the end face of bearing one end, one end face of housing is connected with the other end of bearing support, the other end is connected with an end face of middle land, be in main shaft one end in the housing, be equipped with friction plate and piston in several successively along the axle head direction, friction plate equidistantly places on the main shaft in several, piston cavity and several quantity and identical with interior friction plate at interval outside friction disc are set respectively on the position of inboard corresponding piston of housing and interior friction plate, outside friction disc alternately vertically in making, between middle land and piston, be equipped with pressure spring, do not have in described piston cavity under the state of pressure liquid oil, pressure spring is tight against at described friction plate piston one end face, outside friction disc combination in making.
Be provided with filler opening at housing corresponding to the radial position of piston cavity.
Bearing support and oil sealing base are provided with outside framework oil seal respectively corresponding to place, described position of bearings.
Break of the present utility model is to aim at the crankshaft-link rod radial column to be plugged with a plurality of friction discs, braking moment is big and steady, abrasion is even, long service life, has good braking ability, can design the quantity of antifriction sheet according to the size of required braking torque, can realize the seriation and the standardized designs of product, help promoting the use of; Because simple in structure, volume is little, makes easy to maintenancely, and user cost is low; Simultaneously flexible to operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 main shaft, 2 oil sealing bases, 3,6 outside framework oil seals, 4 needle bearings, 5 bearing supports, 7 housings, 8 pistons, 9 pressure springs, 10 middle lands, 11 outside friction discs, 12 interior friction plates, 13 seal rings, 14 oil inlet and outlets.
Embodiment
Below in conjunction with drawings and Examples the utility model and advantage thereof are described further.
Contrast Fig. 1, break of the present utility model mainly is made up of parts such as interior friction plate 12, outside friction disc 11, main shaft 1, pressure spring 9, piston 8, housing 7, oil sealing base 2, bearing support 5, middle lands 10.Main shaft 1 is bearing on the bearing support 5 by needle bearing 4.Oil sealing base 2 is sealed on bearing support 5 and is equipped with on the end face of bearing 4 one ends, and connects with screw.One end of housing 7 is connected with screw with the other end of bearing support, and the other end is connected with screw with an end of middle land.In bearing support 5 and oil sealing base 2, be respectively arranged with outside framework oil seal 3,6 corresponding to bearing 4 positions.Be in an end of the main shaft 1 in the housing, be equipped with friction plate 12 and piston 8 in several successively along the axle head direction, friction plate 12 equidistantly places on the main shaft 1 in several.Be provided with filler opening 14 at housing corresponding to the radial position in cylinder hole.Cylinder hole and several quantity and identical with interior friction plate at interval outside friction disc 11 are set respectively on the position of housing 7 inboard corresponding pistons 8 and interior friction plate 12, and outside friction disc alternately vertically in making.Piston 8 is equipped with seal ring 13, is used for sealing the interior liquid oil of oil pocket of cylinder hole and piston formation.Be drilled with one group of blind hole of varying number on piston 8 ear end faces, in put pressure spring 9, in the middle of an end of pressure spring 9 is against on the land 10.
During work, piston 8 is under the effect of spring 9, and friction plate 12 combines with outside friction disc 11 in promoting, even motor under the effect of high pressure oil, can not rotate, this state is a Normally closed type.When the hydraulic oil that connects certain pressure at oil inlet and outlet 14 places, pressure oil will promote the tension force that piston 8 overcomes pressure spring 9, produce motion, and friction plate 12 is thrown off revolution with outside friction disc 11 in making.Pressure oil off-load in piston 8, piston 8 make inside and outside friction plate combination under the tension force effect of pressure spring 9, promptly recover normally off again.Utilize inside and outside friction plate combination and throw off this two states, but but make oil hydraulic motor transfer of torque fast braking again.
Size according to braking torque, under the prerequisite of the radial dimension that does not need to change break,, regulate braking moment by the quantity of increase and decrease friction plate, can realize the seriation and the standardized designs of the utility model product, help promoting the use of of the utility model product.
