Abstract
The invention provides a gear-like rack mechanism which comprises a rolling wheel (1), a shaft (2), a supporting body (3), a screw (4), roll balls (5), a guide pipe (6) and the like. The rolling wheel (1) is matched with shaft holes (31) through the shaft (2), the screw (4) is inserted in to a hole (33), a raceway body (32), a roll ball groove (11), a roll ball groove (41) and the guide pipe (6) form a closed circulation raceway, and the roll balls (5) roll in the raceway. The screw (4) is provided with the spiral roll ball grooves (41), the groove shape of the roll ball groove (41) is arranged to be capable of containing the roll balls (5); the roll ball groove (11) in the rolling wheel (1) and the roll ball groove (41) form the raceway of the roll balls (5), the raceway in the shape of a sweeping-out spiral line. The raceway body (32) on the supporting body (3) is processed according to the spiral line of the roll ball groove (41), and when the roll ball (5) enter or roll out of the raceway body (32), a roll ball guiding structure is arranged to enable the roll ball to go in and out of the raceway conveniently. The gear-like rack mechanism has the advantages of being low in friction coefficient and high in precision, and can meet part of the requirements of a gear rack transmission mechanism.
Description
Technical field
The present invention relates to a kind of mechanical transmission mechanism, particularly relate to a kind of type gear rackwork.
Background technique
Rack pinion and ball-screw-transmission, have a wide range of applications in manufacturing automation.Ball-screw-transmission precision is high, rubs little, is widely used, and is made up of, can only carries out the straight line motion of nut nut, screw rod and ball etc.And rack pinion, transmission efficiency is low, and precision is low.
Summary of the invention
Be overcome the technical disadvantages of rack pinion and ball-screw-transmission in technical problem to be solved by this invention, provide a kind of rolling type type gear rackwork.
Technological scheme of the present invention: a kind of type gear rackwork, comprise roller 1, axle 2, support 3, screw rod 4, ball 5, conduit 6 etc., described roller 1 is coordinated with axis hole 31 by axle 2; In described screw rod 4 patchhole 33; The circulation raceway that described raceway 32, ball grooves 11, ball grooves 41 and conduit 6 composition is closed, ball 5 is being rolled into interior rolling.
Described screw rod 4 is processed with spiralling ball grooves 41, and the flute profile of ball grooves 41 is as the criterion to hold ball 5; Ball grooves 11 on described roller 1 and ball grooves 41 form the raceway of ball 5, and its shape is that helix scans.
Raceway 32 on described support 3 goes out according to the helix processing of ball grooves 41, has ball guide structure, facilitate ball to pass in and out raceway when ball 5 enters or roll out raceway 32.
The invention has the beneficial effects as follows: the invention provides a kind of type gear rackwork, there is low coefficient of friction, high-precision feature, and the needs realizing part rack and pinion drive mechanism.

In figure: 1 roller, 2 axles, 3 supports, 4 screw rods, 5 balls, 6 conduits, 11 ball grooves, 31 axis holes, 32 ball grooves, 33 holes, 41 ball grooves.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1 and Figure 2, a kind of type gear rackwork of the present invention, comprise roller 1, axle 2, support 3, screw rod 4, ball 5, conduit 6 etc., roller 1 is coordinated with axis hole 31 by axle 2, in screw rod 4 patchhole 33.As shown in Figure 3, Figure 4, the circulation raceway that raceway 32, ball grooves 11, ball grooves 41 and conduit 6 composition is closed, ball 5 is being rolled into interior rolling.When screw rod 4 rotates, promote ball 5 what close and be rolled into interior rolling, and pushing rolling wheels 1 rotates around axle 2, completes transmission requirement.
As shown in Figure 1, Figure 2, Figure 3 shows, screw rod 4 is processed with spiralling ball grooves 41, and the parameter of helix requires to determine with transmission, and the flute profile of ball grooves 41 is as the criterion to hold ball 5, can be multistage curve, can also be single curve; Ball grooves 11 on roller 1 and ball grooves 41 form the raceway of ball 5, and its shape is that helix scans, and the flute profile of ball grooves 11 is as the criterion to hold ball 5, and can be multistage curve, can also be single curve.Raceway 32 on support 3 goes out according to the helix processing of ball grooves 41, has ball guide structure, facilitate ball to pass in and out raceway when ball 5 enters or roll out raceway 32.
The foregoing is only one embodiment of the present of invention, do not limit the present invention, all at basic conception according to the present invention, any amendment done, equivalent replacement, improvement etc., all should be included among protection scope of the present invention.
