Abstract
The invention discloses an interlocking tooth synchronous belt pulley component with reversal no-clearance drive, which is formed by the connection of a main belt pulley and a belt pulley pair which are provided with pin holes with different dimensions on the same diameter by a pin and a pin sleeve. The main belt pulley pin hole and the pin form an interference fit; the belt pulley pair pin hole and the pin form a clearance fit by the pin sleeve; the end surface where the two belt pulleys are contacted with each other is provided with a ring trough which is internally provided with a torsion spring; one end of the torsion spring hooks the main belt pulley pore and the other end thereof hooks the belt pulley pair pore so as to form the interlocking tooth synchronous belt pulley. The interlocking tooth synchronous belt pulley is engaged with a normal synchronous belt so as to compensate the side clearance between the belt and the gear which is caused by factors such as manufacture and installation, etc., thus ensuring the reversal transmission without clearance, improving the transmission precision of the synchronous belt transmission system and carrying out transverse position limitto the synchronous belt which can adjust the reversal instant driving torque by replacing the fixed position of the pin hole and changing the deformation degree of the torsion spring. The interlocking tooth synchronous belt pulley is suitable for long distance synchronous belt engagement transmission which achieves high motion precision by reversal driving torque.

Described secondary pulley pin-and-hole group is five pin-and-holes for every group, and the pin-and-hole of major and minor belt wheel is arranged in to be divided equally on the major and minor belt wheel on corresponding some belt wheel teeth position, when the different pin-and-holes of secondary pulley are installed, guarantees major and minor belt wheel tooth both sides profile of tooth correspondence.
Have the different through hole of diameter on the described spacing shim.
The beneficial effect that the present invention has is:
This assembly only requires that as band driving wheel use synchronously synchronous tape spool gets final product for the straight circular shaft of band keyway.By the engagement of this belt wheel and common synchronous band, can compensate the band and wheel running clearance that cause by factors such as manufacturing, installations, guarantee oppositely no gap transmission, improved the transmission accuracy of synchronization belt transmission system, and can carry out cross spacing synchronous band; In addition, this synchronous pulley can be by changing the pin-and-hole fixed position, and the amount of deformation that changes torsion spring is adjusted the instantaneous driving torque size of counter-rotating.This belt wheel is fit to reach by the counter-rotating driving torque the synchronous band of the long distance engagement driving of high kinematic accuracy.

Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, shown in Figure 3, the present invention has keyway 7 on main pulley 1, and axis hole cooperation place 3 sent out blue by the major-minor belt wheel is Spielpassung.As shown in Figure 5, have pin-and-hole on main pulley 1 and the secondary pulley 2 same diameters, two pin-and-holes on the main pulley 1 become 180 ° of distributions, the one group of pin-and-hole on the secondary pulley 2 and the pin-and-hole of another group same number are symmetrically distributed by center of rotation, wherein main pulley pin-and-hole 11 and pin 5 interference fit, have annular groove 10 in the main pulley 1, annular groove 10 is equipped with torsion spring 4, one end of torsion spring 4 catches on the torsion spring fixed hole 8 of main pulley 1, the other end of torsion spring 4 catches on the torsion spring fixed hole 8 of secondary pulley 2, the outside of main pulley 1 and secondary pulley 2 is equipped with main pulley rib 15 and secondary pulley rib 16 respectively, carries out spacing to the belt horizontal looseness.One group of pin-and-hole end face of 180 ° of distributions of secondary pulley rib 16 outer one-tenth is equipped with spacing shim 14, and pin cover 13 passes spacing shim 14 macropores, and pin overlaps 13 small end outside threads and is threaded with pin interior threaded hole 9, and secondary pulley pin-and-hole group 12 is a Spielpassung with pin cover 13.
Described secondary pulley pin-and-hole group is five pin-and-holes for 12 every groups, and the pin-and-hole of major and minor belt wheel is arranged in to be divided equally on the major and minor belt wheel on corresponding some belt wheel teeth position, when secondary pulley 2 different pin-and-holes are installed, guarantees major and minor belt wheel tooth both sides profile of tooth correspondence.
As shown in Figure 6, have the different through hole of diameter on the described spacing shim 14.
Working principle of the present invention is as follows:
As shown in Figure 1, intrinsic main pulley rib 15 on the main pulley 1 is along circumferentially being symmetrically distributed with two main pulley pin-and-holes 11, main pulley pin-and-hole 11 and pin 5 interference fit; Secondary pulley 2 is along circumferentially being symmetrically distributed with two groups or above secondary pulley pin-and-hole group 12; As shown in Figure 2, main pulley is sent out blue axle and secondary pulley and is sent out interporal lacuna blue and cooperate, and obtains axial coaxality; Overlap 13 outside threads by pin and be screwed into pin interior threaded hole 9, realize that pin overlaps the Spielpassung of 13 optical axis ends and secondary pulley pin-and-hole group 12, install when being with synchronously that pin overlaps 13 optical axis ends and enters secondary pulley pin-and-hole group 12, guarantee not side set of major-minor belt wheel tooth, the convenient tooth of band synchronously embeds pulley groove; Tensioning is synchronously behind the band, screw out screw cover 13 a little, spacing shim 14 is laterally moved, become the small aperture by the large aperture, do not allow screw to overlap 13 optical axis ends and enter secondary pulley pin-and-hole group 12, it is constant to satisfy between secondary pulley rib 16 and the main pulley rib 15 width, makes the belt cross spacing; At this moment, because of annular space between pin 5 and the secondary pulley pin-and-hole group 12 exists, main pulley 1 and secondary pulley 2 are because of torsion spring 4 effects, can rotate the formation side set mutually, compensating the backlash in the synchronous band transmission, effect is with 6 and main pulley 1, secondary pulley 2 are final realizes the transmissions of no gap as shown in Figure 4 synchronously.The synchronous pulley that above-mentioned principle constitutes is an independently assembly, only requires that synchronous band transmission shaft gets final product for band keyway circular shaft.As shown in Figure 3, torsion spring 4 is installed in the annular groove 10, has torsion spring fixed hole 8 in the annular groove 10, when torsion spring 4 is installed, two of torsion spring 4 is contained in respectively in the torsion spring fixed hole 8 of main pulley 1 and secondary pulley 2.During installation, by the cooperation of adjustment pin 5 with secondary pulley pin-and-hole group 12 different pin-and-holes, can make torsion spring 4 obtain different initial deformation amounts, the initial deformation amount is big more, and secondary pulley 2 instant reversal driving torques are big more.
