Abstract

The utility model relates to a worm pump with a ring and a gear, which is composed of a star gear, a worm, and an upper and a lower pump body, wherein, the gear teeth of the star gear is composed of a plurality of circular disks which are uniformly distributed and installed on a wheel hub, and the radial section of a helical groove of the worm is a circular shape. The utility model has the characteristics of simple structure, stable work, easy fabrication, high efficiency and long service life. The media from gases to high-viscosity liquid or multiphase fluid can be conveyed by the utility model.

Description

Worm pump with a ring and a gear
The utility model belongs to a kind of positive displacement worm pump.
Existing worm pump is by having the spiral fluted rotor and carrying and supercharging mechanical (gas or liquid) with the displacement fluid that the star-wheel and the shell of its gear motion are formed.Accompanying drawing 1 is the structural drawing of existing star-wheel Worm type oil hydraulic pump.It is made up of two star-wheels and a worm screw.Star-wheel (2) becomes the spatial vertical interlaced arrangement with the rotational axis of worm screw (4).Its gear motion is equivalent to the worm and gear transmission, and star-wheel is equivalent to worm gear.The spiral chute two ends of worm screw (4) communicate with oil sucting cavity (7) and oil-discharging cavity (6) respectively, with the star-wheel gear teeth of spiral chute engagement the spiral chute separated into two parts, separately with oil sucting cavity and oil-discharging cavity.By the gear motion of star-wheel and worm screw, realize the continuous alternate of spiral chute two-part volume, realize the compression and the conveying of liquid or gas, star-wheel is different with the shape of worm screw, can be made into difform worm pump.Advantages such as this worm pump has simple in structure, and the pulsation of worm screw stress balance, discharge capacity is little obtain the attention of a lot of industries.But it exists following shortcoming: (1) worm screw is that hourglass worm, the worm spiral groove curved surface of a bull is the non-straight grained helical of opening up that helix angle alters a great deal, can't be with the machining such as the car of routine, mill, mill etc. processes, generally can only be similar to processing or use non-traditional machining with the numerical control method, the processing cost height, and be difficult to guarantee precision.(2) because the profile of tooth of star-wheel has the fixedly line of rabbet joint, and with the worm meshing campaign, star-wheel is easy to wear, the wearing and tearing post gap can't compensate.The efficient of pump is reduced greatly.Above shortcoming especially worm screw is difficult to processing, has limited promoting the use of of star-wheel worm pump greatly.
The purpose of this utility model, provide a kind of novel star-wheel worm pump, the profile of tooth of star-wheel has brand-new shape, spiral chute on the worm screw has new sectional shape, and it can keep existing all advantages of star-wheel worm pump, and can overcome worm screw and be difficult to process the shortcoming easy to wear with star-wheel, its long service life, the efficient height, processing technology is easy, the accuracy of manufacturing height.
The technical solution that the utility model proposes is: encircle the star-wheel worm pump by the garden that star-wheel, worm screw and the upper and lower pump housing are formed, the gear teeth that its major technique feature is a star-wheel coil (8) by some gardens to be formed, the garden dish evenly distributes and is installed on the wheel hub (4),, locking fixing with nut (5).Whole star wheel structure is installed in the upper and lower pump housing (6) and (11) by central shaft (10).Worm screw (1) is connected with main shaft (3) by key (12), the axis of main shaft (3) and the perpendicular interlaced arrangement of star-wheel central shaft (10), and main shaft (3) is contained in the upper and lower pump housing (6) and (11), and the spiral chute radial cross section on the worm screw is shaped as garden shape.Have fluid on the upper and lower pump housing (6) and (11) and enter chamber (7) and discharge side (2).
Each star-wheel garden dish garden Zhou Shangke of garden ring star-wheel worm pump is equipped with seal ring (9), and garden ring star-wheel can be one, two, more than three or three.
Technological guidance's thought of the present utility model is to make garden its working principle of ring star-wheel worm pump that is proposed identical with existing star-wheel worm pump, promptly utilizes the conjugate movement of worm screw and garden ring star-wheel to form worm spiral groove curved surface.Do not interfere again in order to obtain maximum actual volume, spiral chute maximum depth radially is the radius of star-wheel garden ring.Therefore, the radial cross section of the worm spiral groove of conjugation is all the part in garden with it.If the garden anchor ring of star-wheel is become milling cutter or emery wheel, in the time of milling cutter or emery wheel self rotation, the motion that work is identical with the worm screw conjugate movement with star-wheel can process the worm spiral groove.Therefore, the worm screw of garden ring star-wheel worm pump can be processed with milling or grinding, has solved the unmanageable problem of general star-wheel worm pump worm screw.Star-wheel is made up of the garden dish, makes easily than integrated type star-wheel, and the garden mill decreases the back and changes easily.On the dish of garden O-ring seal is housed, seal ring can be made with high-abrasive material, to improve the life-span.When seal ring has certain wearing and tearing, the elasticity of reliable sealing circle compensates.
This model utility has tangible economic effect and use value.Because the worm screw of this pump can accurately be cut and grinding, and star-wheel can add seal ring, so the pump chamber sealing is very high, can make the compressor of high compression ratio.This pump worm screw and star-wheel because make easily, available height is hard, high-abrasive material manufacturing, the worm screw that makes pump and star-wheel wear resistance improve, but transfer of highly viscous contains the very high medium of solid particle ratio.So from gas to the high viscosity liquid or the medium of multimachine fluid all can carry.Efficient height, long service life.
Accompanying drawing 1 is existing star-wheel worm pump structural drawing.
Accompanying drawing 2 is garden ring star-wheel worm pump structural drawing.
In the accompanying drawing 1: the 1-worm screw, the 2-star-wheel, the 3-lower pump body, the 5-upper pump casing, the 4-main shaft, the 6-discharge side, 7-enters the chamber.
In the accompanying drawing 2: the 1-worm screw, the 2-discharge side, the 3-main shaft, the 4-wheel hub, the 5-nut, the 6-upper pump casing, 7-enters the chamber, 8-garden dish, 9-seal ring, 10-star-wheel central shaft, 11-lower pump body, 12-key.
Accompanying drawing 2 is embodiments of the present utility model, this star-wheel worm pump is made up of worm screw of two star-wheels, star-wheel is arranged symmetrically in the worm screw both sides, and respectively with worm meshing, power (torque) is imported by main shaft (3), driving worm screw (1) rotates, worm screw and garden dish (8) gear motion drive star-wheel central shaft (10) and rotate, fluid enters the spiral chute of worm screw (1) from entering chamber (7), along with the engagement of worm screw (1) with garden dish (8), with spiral chute with enter that the chamber separates and be communicated with discharge side (2), along with the continuation gear motion of worm screw (1) with garden dish (8), the spiral chute volume reduces gradually, and fluid is discharged from discharge side (2), realizes the conveying of fluid.
