Abstract
A radial-plunger type multiple-action inner curved hydraulic motor is mainly suitable for hydraulic devices in harsh working environment such as furnace front and the like and mainly formed by an output shaft, an installation seat, a gear ring, a plunger, a driving disk, a rear seat, an oil distribution disk, a brake, a brake spindle and the like. A rail of the hydraulic motor uses the gear ring processed according to a single curve rail formula to meet movement of the plunger. The use of various sealing rings is capable of realizing no evident leakage between a high-pressure cavity and a low-pressure cavity, and simultaneously tiny amount of leakage can meet lubrication need of bearings, thereby guaranteeing no excessively high temperature in running to damage machines.
Description
Technical field
The utility model relates to a kind of oil hydraulic motor, be specifically related to a kind of rugged environment that are applicable to, the instability of hydraulic system changes uses influence less to it, and it is less that the oil pocket sealing is influenced by hydraulic system, applicable to the radial plunger type multiple-action inner curved hydraulic motor of bad working environments.
Background technique
Oil hydraulic motor is a kind of hydraulic driving mode that is of wide application, the oil hydraulic motor that uses in casthouse equipment at present comes oil sealing with oil sealing usually, but blast furnace equipment hydraulic system piping layout is longer, the hydraulic system instability often takes place, the phenomenon of oil hydraulic motor leakage of oil and oil seal failure often takes place in present use, environment is abominable before the State of Blast Furnace simultaneously, causes the working life of conventional motor shorter.Traditional the type oil hydraulic motor trajective curve is a build-up curve simultaneously, and curve produces certain influence to the flow pulse rate of motor usually in the transition of accelerating sections and braking section.
Summary of the invention
The utility model purpose provides a kind of low speed high torque oil hydraulic motor that is applicable to that the stokehold is used, this motor track adopts the gear ring of simple curve track formula processing to satisfy plunger motion, the use needs that use the high strength sealing system to adapt to simultaneously to satisfy the stokehold environment.
The purpose of this utility model is achieved in that a kind of radial plunger type multiple-action inner curved hydraulic motor, comprise fitting seat and output shaft, output shaft is by location of the double cone roller bearing in the fitting seat and support, between two bearings, seal by rotating seal ring, output shaft is connected with drive plate by spline, fitting seat is connected gear ring with back seat by bolt, the gear ring two sides is equipped with seal ring, the a plurality of plungers of drive plate circumference in the chamber, tooth lacks the transmission of tooth difference common the composition on plunger on the drive plate and the gear ring, break is connected by bolt with back seat, the brake axle of break is connected with drive plate by spline, be provided with brake block at the brake axle end, brake block matches with sliding piston.10 plungers of drive plate circumference in the chamber have 8 teeth on the gear ring, constitute the typical tooth difference transmission of lacking.Gear ring processes according to complete simple curve formula.
The radial plunger type multiple-action inner curved hydraulic motor that the utility model provides, motor track adopt the gear ring of simple curve track formula processing to satisfy plunger motion; Tooth on drive plate upper plug and the gear ring is common forms few tooth difference transmission, is convenient to start, and the tangential force that plunger acts on the counter-force gained on the gear ring in the time of can guaranteeing any position can promote the drive plate rotation.Lowest starting pressure can reach 1.5MPa.The use of each RunddichtringO can allow not have significantly in the middle of high pressure and the low-pressure cavity and leak, and the leakage rate of trace can satisfy the lubricated needs of bearing simultaneously, and temperature can be not too high and damage in operation process to guarantee machine.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a sectional structure schematic representation of the present utility model.
Fig. 2 is a working principle schematic representation of the present utility model.
Fig. 3 is a gear ring track schematic representation of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of radial plunger type multiple-action inner curved hydraulic motor, comprise fitting seat 2 and output shaft 1, it is characterized in that: output shaft 1 is by 10 location of the double cone roller bearing in the fitting seat 2 and support, between two bearings, seal by rotating seal ring 13, output shaft 1 is connected with drive plate 5 by spline, fitting seat 2 is connected gear ring 3 with back seat 6 by bolt, gear ring 3 two sides are equipped with seal ring 14, the a plurality of plungers 4 of drive plate 5 circumference in the chamber, tooth lacks the transmission of tooth difference common the composition on plunger 4 on the drive plate 5 and the gear ring 3, break 9 and back seat 6 are connected by bolt, the brake axle 8 of break 9 is connected with drive plate 5 by spline, is provided with brake block 11 at brake axle 8 ends, and brake block 11 matches with sliding piston 12.
10 plungers of drive plate 5 circumference in the chamber have 8 teeth on the gear ring 3, constitute the typical tooth difference transmission of lacking.
Inner curve in the utility model is meant: the equidistant curve of curtate epicycloid (envelope), i.e. gear ring curve.
The simple curve formula that is adopted is:
Working procedure of the present utility model is as follows:
Radial plunger type multiple-action inner curved hydraulic motor is by output shaft 1, fitting seat 2, gear ring 3, plunger 4, drive plate 5, oil distribution casing 7, back seat 6, break 8 component such as grade are formed, and at first the low pressure oil that is provided by oil pump is moved backward by braking hydraulic fluid port 15 promotion sliding pistons 12, the friction plate of holding tightly is unclamped, the high pressure oil that is provided by oil pump enters drive plate 4 by the oil inlet hole of oil distribution casing 7 again, and then promotes plunger 4 and outwards move, owing to whenever all there being the tooth waist on plunger 4 and the gear ring 3 to contact, this will make hydraulic coupling decompose and produce tangential force and normal force, and wherein the tangential force transmitting torque makes drive plate 5 rotations.When plunger 4 arrived that the tooth root position begins to move inward on the gear rings 3, drive plate 5 can rotate to hydraulic fluid port the position of oil distribution casing oil outlet accordingly, plunger cavity by flowing out along oil outlet.Owing to 8 teeth are arranged on the gear ring 3, when plunger per 4 during through a tooth, plunger 4 is once reciprocating, and drive plate 5 rotates a circle, and plunger 4 to-and-fro motion 8 times are so form multifunctional working method.
