Abstract

The utility model discloses a hydraulic multiple-disc brake which is suitable for mechanical brake in the hoisting industry, the mine industry, the mechanical industry and the like. The hydraulic multiple-disc brake is characterized in that brake discs are arranged on an internal spline of a shell by an external spline; friction plates are arranged on an external spline of a motor shaft by an internal spline; the brake discs and the friction plates are in staggered arrangement with intervals and are arranged between a front cover and a piston; the piston is arranged in a cylinder body; an adjusting bolt penetrating through a rear cover is arranged on the piston; a spring is arranged between the piston and the rear cover; an oil filling port and an oil filling bolt are arranged on the shell; an oil cylinder is arranged between the cylinder body and the piston; a sealing ring is arranged at the clearance between the cylinder body and the piston; the front cover is connected with the shell by a bolt; the shell and the cylinder body are connected with the rear cover by bolts; and the whole brake is connected on a base by bolts. The brake moment of the brake can be adjusted according to different devices as required; in addition, the hydraulic multiple-disc brake has the advantages of simple structure, small size, low cost, labor-saving operation and convenient installation and maintenance.

Description

The hydraulic multiple disc break

Technical field: the utility model relates to a kind of braking machinery, and particularly a kind of hydraulic multiple disc break is applicable to the mechanical braking in the industries such as lifting, transportation, metallurgy, mine, machinery, chemical industry, harbour.

Background technique: traditional drum-type, disk type braker are after wheel footpath, disk track, power source and profile are determined, moment is determined immediately, because of moment is limited in scope, it can not be adjusted the requirement that braking moment varies in size according to distinct device, its complex structure in addition again, volume is big, adjusts, keeps in repair all inconveniences, therefore can not satisfy user's demand.

Model utility content: in order to solve the complex structure that exists in above-mentioned drum-type, the disk type braker, volume is big, installation, maintenance problems such as all inconvenience and braking moment size is non-adjustable, the purpose of this utility model is to provide a kind of braking moment adjustable size, and simple in structure, volume is little, easily processing, braking is reliable, rapid operation, and installation, maintenance is hydraulic multiple disc break easily all.

The technical solution of the utility model realizes in the following manner:

A kind of hydraulic multiple disc break, it comprises protecgulum, shell, cylinder body, piston, brake disc, friction plate, bonnet and spring, it is characterized in that: brake disc is contained on the internal spline of shell by external splines, friction plate is contained on the external splines of motor shaft by internal spline, brake disc and friction plate are staggered to be spaced, and be contained between protecgulum and the piston, piston is contained in the cylinder body, the adjustment bolt that passes bonnet is housed on the piston, between piston and the bonnet spring is housed, oil hole is arranged on the shell, the oiling bolt is arranged on the oil hole, between cylinder body and the piston oil cylinder is arranged, the gap location of cylinder body and piston is equipped with seal ring, protecgulum is connected with shell by bolt, shell, cylinder body is connected with bonnet by bolt, and whole break is connected on the pedestal by bolt.

Good effect of the present utility model is:

1. to have braking moment adjustable for this product, and adjustment range is big, and it can be adjusted the requirement that braking moment varies in size according to distinct device, only can realize by the quantity that increases (subtracting) brake disc and friction plate.

2. this product is when keeping in repair or being in an emergency, and manually bolt is adjusted in rotation, can in time declutch, so that workpiece arrives specified position.

3. this product structure is simple, volume is little, easy processing, cost are low, and installation, maintenance all makes things convenient for.

4. the shell of this product is provided with oil hole, so that lubricated brake disc can move brake disc smoothly on shell.

Description of drawings:

Fig. 1 is a general structure schematic representation of the present utility model

Fig. 2 is the left view of Fig. 1

Fig. 3 is the A portion enlarged view of Fig. 2

Fig. 4 is the B portion enlarged view of Fig. 2

Embodiment: the utility model is elaborated below in conjunction with accompanying drawing

By concrete structure of the present utility model as can be seen among Fig. 1, Fig. 2, Fig. 3, Fig. 4, it is made up of protecgulum 3, shell 4, cylinder body 8, piston 10, brake disc 1, friction plate 2, bonnet 11, spring 14 etc.

Brake disc 1 is contained on the internal spline of shell 4 by external splines, friction plate 2 is contained on the external splines of motor shaft 18 by internal spline, both interlock brake disc 1 and friction plate 2 and are spaced, and be contained between protecgulum 3 and the piston 10, piston 10 is contained in the cylinder body 8, adjustment bolt 13 passes bonnet 11 and is contained on the piston 10, spring 14 is housed in the piston 10, spring 14 ends withstand on the bonnet 11, oil hole 5 is arranged on the shell 4, oiling bolt 6 is arranged on the oil hole 5, between cylinder body 8 and the piston 10 oil cylinder 9 is arranged, the gap location of cylinder body 8 and piston 10 is equipped with seal ring 7, and protecgulum 3 is connected with shell 4 by bolt 16, shell 4, cylinder body 8 is connected with bonnet 11 by bolt 15, and whole break is connected on the pedestal 17 by bolt 12.

Working principle of the present utility model is: when work mechanism is worked, feed pressure oil in the oil cylinder 9, under the effect of pressure oil, piston 10 moves to bonnet 11 directions, pressure spring 14, and unclamp roof pressure to brake disc 1 and friction plate 2, brake disc 1 is separated with friction plate 2, realize declutching.

During braking, pressure oil in the oil cylinder 9 discharges, spring 14 release pressures, promoting piston 10 simultaneously moves to protecgulum 3 directions, piston 10 tight brake disc 1 of extruding and friction plates 2, because the internal spline on the friction plate 2 links to each other with the external splines on the motor shaft 18, motor stall under frictional force action realizes brake sticking brake.

The manual work principle is: when being in an emergency or keep in repair, pressure oil discharges, and this moment, bolt 13 was adjusted in rotation, and drives piston 10 and move to bonnet 11 directions, realizes declutching.

When between brake disc 1 and the shell 4 grating being arranged, to back out oiling bolt 6 and in oil hole 5, add butter, lubricated brake disc 1 and shell 4 make brake disc 1 motion smoothly on shell 4.
