Abstract
A ball collision coupling belongs to mechanical transmission parts of rotational movement in mechanical engineering. The present invention includes the driving end, the driven end, wedge-shaped block and ball. There is annular recess inside of one end and the ring groove on the other end adopted by the driving and driven ends. At least three wedge-shape blocks is fixed in the annular recess of two ends, and the number in the driving end is different from the driven end. The driving end centers the driven end each other and there is some place between radial and axial direction. The two end can rotate freely and don't effect each other. The ball is installed in the hollow of two panels. The invention can decrease the loading torque of the driving axis when it enables and the need of neutrality of two axis.
Description
Technical field
The present invention relates to a kind of steel-ball collision-type coupler, be used for transmitting the motion between the diaxon, belong to the mechanical part of conveying rotary motion in the mechanical engineering.
Background technique
Coupling is the axle that is used for connecting two sections separation, and the two is together turned round, and is a kind of component commonly used in order to transmitting movement and moment of torsion.Common coupling can be divided into rigid coupling and flexible coupling.Rigid coupling is made up of rigid member, and is simple in structure, do not have the ability of buffering absorbing, requires the higher to neutrality of diaxon during use, can produce very big load torque to prime mover during startup; The flexible coupling kind is more, relies on the relative displacement of element or the resiliently deformable compensating error of elastic element usually, and cost is higher, and volume is bigger, uses also to be subjected to certain limitation.
Summary of the invention
The purpose of this invention is to provide a kind of steel-ball collision-type coupler, with overcome existing rigid coupling to diaxon neutrality is required high, during startup prime mover is produced defective than the heavy load moment of torsion; It is low to have cost simultaneously, and volume is little, uses advantage flexibly.
Technological scheme of the present invention is as follows: a kind of steel-ball collision-type coupler, it is characterized in that: described coupling is by drive end, driven end, wedge-shaped blocks and steel ball are formed, described drive end and driven end all adopt a side inside to have circular groove, opposite side to stretch out the disk of axle journal, and the center of drive end and driven end is respectively equipped with driving shaft center hole and driven shaft center hole; At least each evenly fixes three wedge-shaped blockss in the circular groove of drive end and driven end, and the quantity of the interior wedge-shaped blocks of drive end circular groove should be different with the quantity of wedge-shaped blocks in the driven end circular groove; The mutual centering of described drive end and driven end, radially with axially leave certain interval, the two can be rotated freely and not influence each other; Described steel ball is contained in the cavity that forms after the two disk centerings.
The preferred technical solution of the present invention is: the quantity of the interior wedge-shaped blocks of the quantity of wedge-shaped blocks and driven end circular groove is relatively prime in the described drive end circular groove.
Centering between drive end of the present invention and the driven end is adopted flange and groove structure.
The present invention compared with prior art has the following advantages and the high-lighting effect: steel-ball collision-type coupler provided by the invention, because drive end and driven end directly do not link together, can reduce the load torque of driving shaft greatly during startup; The coaxiality error of the adjustable gaps joint diaxon between drive end and the driven end is to reduce diaxon requirement of neutral; Have simple in structurely simultaneously, volume is little, and cost is low, uses flexibly, and is reliable and be convenient to advantage such as maintenance.

Embodiment
With reference to the accompanying drawings principle of the present invention, structure and working procedure are further described.
Fig. 1 is the overall structure schematic representation of steel-ball collision-type coupler, and this coupling is mainly by drive end 1, driven end 2, and wedge-shaped blocks 3 and steel ball 4 are formed, and drive end and driven end all adopt a side inside to have circular groove 5, opposite side to stretch out the disk of axle journal 6.There is a drive end center hole 7 at the drive end center, and drive end links to each other with the input shaft (not shown) by this center hole in use.There is a driven end center hole 8 at the driven end center, and driven end links to each other with the output shaft (not shown) by this center hole in use.Wedge-shaped blocks 3 by connecting bolt 9 by in the uniform ring shaped slot 5 that is fixed on drive end and driven end, at least each evenly fixes three wedge-shaped blockss in the circular groove of drive end and driven end, and the quantity of two ends wedge-shaped blocks should be different, preferably keep relatively prime, so at any time, the cavity that all has at least drive end, a driven end to surround is in not closed state, and steel ball can freely pass through.One hand-hole 12 is arranged on the outer rim of driven end, be used for injecting steel ball, inject the back sealing.
During installation, the microcephaly of wedge-shaped blocks 3 points to the center of ring shaped slot; The mutual centering of drive end and driven end, and at the radial and axial certain interval that leaves, the size of this gap to be being as the criterion less than steel ball size, and guarantee that drive end and driven end can freely rotate, tight pressure mutually.Centering between drive end and the driven end can be adopted flange and groove structure, and the flange 10 on the drive end aligns with groove 11 on the driven end, and the two can freely rotate and is independent of each other.
Steel ball is injected in the cavity of drive end and driven end formation from hand-hole 12, hand-hole is sealed.The quantity of steel ball should satisfy following requirement: can not be very few, and the medium that causes transmitting kinetic energy is very little and can't transmitting movement and moment of torsion; Can not be too much, cause the steel ball can't unrestricted motion in cavity.
In the starting stage of coupling load, driving shaft drives the drive end rotation, and at this moment, steel ball 4 in the cavity is stirred in the side of wedge-shaped blocks, makes steel ball 4 have a certain size kinetic energy, passes cavity, arrives driven end.After arriving driven end, driven end is given with energy transfer in the side of steel ball 4 collision driven end wedge-shaped blockss, drives driven shaft and rotates, and reaches the effect of shaft coupling motion.
This coupling both can one-way only operation, can use again and transmit the occasion that circulation bidirectional rotatablely moves.
