The invention can realize the motion transmission at a longer distance, is suitable for overspeed starting due to good rigidity and great low flexibility of the steel belt and suitable for various harsh environments due to excellent heat resistance and corrosion resistance, can not generate the inertial oscillation of a similar gear and a synchronous belt and has high positioning accuracy during starting and stopping.
Description
Technical field
The present invention relates to a kind of Steel Belt Transmission mechanism, need specifically to be used to the high-speed starting stepless change, the transmission that span is bigger belongs to the precision mechanical transmission technical field.
Background technique
In existing procucts, precision mechanical transmission is many with engagement driving and belt transmission.Engagement driving is made and installation precision requires very high.And be difficult for realizing stepless change, two distance between shafts are difficult to realize with engagement driving when big.There is slip in the course of the work in belt, so can not realize accurate location, in precision drive, is difficult to use.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of Steel Belt Transmission mechanism is provided, this driving mechanism can be realized the transmission of movement of longer distance; The steel band good rigidly, stretchability and little, transmission accuracy is high, can be applicable to the startup of hypervelocity.
According to technological scheme provided by the invention, a kind of Steel Belt Transmission mechanism comprises motor, motor seat, coupling, load connecting base, transmission shaft, jump ring, roller bearing follower, compact heap, bearing, steel band connecting base, fixed base; Said bearing is placed in the bearing hole of load connecting base, the rotatingshaft load connecting base of packing into, and fix with the retainer nut; Said motor seat is fixed on the load connecting base; Coupling is contained in the axle head of transmission shaft, and motor is fixedly connected with the motor seat; The roller bearing follower compact heap of packing into inserts and jump ring is snapped in the jump ring groove on the pin with pin; The steel band connecting base fixed base of packing into; Steel band passes the load connecting base and fixes with the steel band connecting base at two ends.
Said compact heap and load connecting base cooperate by bolt, the axial displacement of restriction steel band between transmission shaft and roller bearing follower.Said load connecting base is connected with load.
Compared with present technology the present invention has the following advantages:
1, can realize the transmission of movement of longer distance.2, steel band good rigidly, stretchability and little is applicable to the startup of hypervelocity.3, superior stepless change.4, heat-and corrosion-resistant property is good, is applicable to various arduous environment.5, can the similar gear of output, be with the sort of inertial oscillation synchronously, Location accuracy is high when starting and stopping.6, simple in structure, installation requirement is low, and is with low cost.7, steel band is as thin as a wafer machinable, can realize the miniaturization of equipment.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe
As shown in Figure 1, comprise 1, motor seat 2, coupling 3, load connecting base 4, transmission shaft 5, jump ring 6, pin 7, roller bearing follower 8, compact heap 9, bearing 10, retainer nut 11, steel band 12, steel band connecting base 13, fixed base 14.
Earlier bearing 10 is placed in the bearing hole of load connecting base 4, fixes then with the rotatingshaft 5 load connecting base 4 of packing into, and with retainer nut 11; Said motor seat 2 is fixed on the load connecting base 4.Pack into the axle head of transmission shaft 5 of coupling 3, motor 1 is fixing with motor seat 2, adjusts coupling position and locking afterwards.Said load connecting base 4 is connected with load.Roller bearing follower 8 compact heap 9 of packing into will be sold 7 then and insert and jump ring 6 is snapped in the jump ring groove on the pin.Steel band connecting base 13 fixed base 14 of packing into.Steel band 12 passes load connecting base 4 and fixing with the steel band connecting base 13 at two ends, compact heap 9 and the 4 assembling adjustment of load connecting base.
The present invention adopts transmission shaft 5 and 4 assemblings of load connecting base, has played good Location accuracy and leading role through bearing 10.Steel band 12 is fixed on the fixed base 14 through steel band connecting base 13, thereby has limited the radial-play of steel band.Compact heap 9 and load connecting base 4 be by bolt, thereby limited the axial displacement of steel band 12 between transmission shaft 5 and roller bearing follower 8, thereby guaranteed enough contact friction forces.Utilize coupling 3 that the power of motor 1 is accurately passed to transmission shaft 5, thereby rotatablely moving of transmission shaft 5 changed into straight line motion.The sense of rotation that changes motor 1 can realize straight reciprocating motion accurately.
The present invention adopts motor 1 to be power source.Motor seat 2 connects motor 1 and load connecting base 4 through bolt.Coupling 3 is given the transmission of power of motor 1 transmission shaft 5, jump ring 6 and is sold 7, has limited the position of roller bearing follower 8 at compact heap 9, thereby guarantees transmission accuracy.Bearing 10 and load connecting base 4 have guaranteed the positional accuracy and the running accuracy of transmission shaft, and retainer nut 11 has limited the play of transmission shaft, has guaranteed transmission accuracy.Steel band 12 is fixed through bolt and steel band fixed base 13, fixed base 14, has guaranteed the installation precision of steel band.
The present invention adopts stretchability and little steel band 12 as driving medium, and compact heap 9 forces 8 pairs of steel bands of roller bearing follower 12 to produce enough precompressions, makes the frictional force between itself and the transmission shaft 5 enough drag load.Frictional force between transmission shaft 5 and the steel band 12 obtains through the precompression that roller bearing follower 8 applies, thereby adjustment roller bearing follower 8 can obtain good transmission performance with pressure.
Working principle of the present invention and working procedure:
When work, motor driven running shaft, running shaft rely on the roller bearing follower to press steel band, lean on its frictional force, will rotatablely move and change into straight line motion, thereby realize high-speed starting, accurate location, stepless change etc.
Notice of the present invention:
1. steel strip surface can not be rough and uneven in surface, and can not be oily.
2. roller bearing follower, bearing is answered intermittent oiling, keeps good lubricated.
