Abstract
The invention discloses a combined coupling, which is used for metal plate strap straightening equipment. The end, with a key slot, of a synchronizing universal coupling with ball and sacker is connected with a first worm shaft of a multi-roller straightener pressing mechanism. An internal spacer bush is arranged on a second worm shaft at the other end, without the key slot, of the synchronizing universal coupling with ball and sacker. Adjusting screws are arranged between the internal spacer bush and an internal expansion sleeve. An external expansion sleeve is sleeved outside the internal expansion sleeve, and is sleeved in a hole of the synchronizing universal coupling with ball and sacker. In the combined coupling, one end of the synchronizing universal coupling with ball and sacker is made into the hole with a relatively greater diameter, the combined expansion sleeve is arranged into the hole at one end of the synchronizing universal coupling with ball and sacker, and the synchronizing universal coupling with ball and sacker and the second worm shaft are locked and loosened conveniently and rapidly by the adjusting screws, so synchronism between the first and second worm shafts still can be well ensued when a relatively greater coaxiality error exists between the worm shaft on an operating side and the worm shaft on a drive side; and simultaneously, when the coupling is assembled, the first and second worm shafts are not required to rotate, so working rollers can be ensured to always keep relatively higher parallelism accuracy, and the coupling is convenient to assemble and disassemble.
Description
Technical field
The present invention relates to iron and steel and non-ferrous metal industry technical field, is a kind of Combined coupler for metal plate and belt equipment for straightening specifically.
Background technique
Coupling between multi-roll straightening machine screw-down fore side and back flow side worm screw has expansion sleeve type coupling, the universal synchronous coupling of Rzeppa type and three kinds of forms of elastic dowel pin shaft coupling both at home and abroad at present, all there is different defects in these three kinds of coupling: (1) expansion sleeve type coupling is combined by two pairs of expansion sleeves and a transmission shaft, although mounting or dismounting are convenient, all can guarantee that any rotation does not occur for fore side worm screw and back flow side worm screw during mounting or dismounting, but this coupling requires very high to the coaxality between fore side worm screw and back flow side worm screw, because the coaxiality error of two worm shafts can make two pairs of expansion sleeve type coupling strength of mutually spraining in rotary course, between expansion sleeve, there is skidding, this skid to accumulate will cause the inconsistent of fore side leading screw and back flow side leading screw displacement amount, and the moment of torsion of depressing motor is larger, this phenomenon is more obvious, causing multi-roll straightening machine upper roller system work roll and lower roll is the not parallel of work roll, due to fore side worm screw and back flow side worm screw apart from each other, coaxiality error between two worm shafts is difficult to control, therefore with expansion sleeve type coupling, occur skidding also just inevitable, so the parallelism that up-down rollers is work roll will check frequently, adjust, working service is extremely inconvenient.(2) the universal synchronous coupling of Rzeppa type: even if this coupling fore side worm shaft and back flow side worm shaft form an angle, still can guarantee the synchronization accuracy of transmission, but position that will be to keyway during the mounting or dismounting of this coupling, cause fore side worm screw or back flow side worm screw must have certain rotation when dress coupling, this rotation will affect the parallelism precision of work roll, affects the correction quality of strip.(3) elastic dowel pin shaft coupling: elastic dowel pin shaft coupling is also a kind of cased muff coupling, this coupling requires also very high to the coaxality of fore side worm shaft and back flow side worm shaft, during simultaneously this coupling assembling, while also existing pin-and-hole position, between fore side worm shaft and back flow side worm shaft, to there is certain angle that relatively rotates, this rotation angle impacts the parallelism precision of work roll, thereby affects the final correction quality of strip.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of Combined coupler, the universal synchronous coupling of Rzeppa type and expansion sleeve are combined, and the worm shaft of fore side and back flow side does not need any rotation, guarantees that two worm shafts have very high synchronization accuracy.
For achieving the above object, one end of synchro-nizing universal coupling with ball and sacker band keyway of the present invention and the worm shaft one of multi-roll straightening machine screw-down are connected; On the worm shaft two with the other end of keyway, inner spacing collar is not housed, adjusting screw is contained between inner spacing collar and interior expansion sleeve, for adjusting the matching gap of outer expansion sleeve and synchro-nizing universal coupling with ball and sacker and interior expansion sleeve and worm shaft two, interior expansion sleeve overcoat has outer expansion sleeve, and outer expansion sleeve is contained in the hole of synchro-nizing universal coupling with ball and sacker.
The present invention compared with prior art, a hole that diameter is larger is made in one end of synchro-nizing universal coupling with ball and sacker, combined type expansion sleeve is packed in the hole of ball cage coupling one end, by the matching gap (or magnitude of interference) of the outer expansion sleeve of adjusting screw adjustment and synchro-nizing universal coupling with ball and sacker and interior expansion sleeve and worm shaft two, when fore side worm shaft and the larger coaxiality error of back flow side worm shaft existence, the synchronism of worm shaft one, two still can be guaranteed well; Meanwhile, while filling this coupling, worm shaft one, two does not need to do any rotation, can guarantee that work roll remains higher parallelism precision, installs and removes very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged view of the built-up section of Fig. 1.
Embodiment
As shown in figure, Fig. 2, synchro-nizing universal coupling with ball and sacker 2 of the present invention is connected with one end of keyway and the worm shaft 1 of multi-roll straightening machine screw-down; On the worm shaft 25 with the other end of keyway, inner spacing collar 7 is not housed, adjusting screw 4 is contained between inner spacing collar 7 and interior expansion sleeve 6, interior expansion sleeve 6 overcoats have outer expansion sleeve 3, outer expansion sleeve 3 is contained in the hole of synchro-nizing universal coupling with ball and sacker 2, by adjusting screw 4, adjust the matching gap (or magnitude of interference) of outer expansion sleeve 3 and synchro-nizing universal coupling with ball and sacker 2 and interior expansion sleeve 6 and worm shaft 25, the effect of inner spacing collar 7 is the distances that move axially while controlling two interior expansion sleeve 6 swellings, prevents from cannot throwing off after swollen too tight of expansion sleeve.The tolerance of size of coupling endoporus is H7, surface roughness Ra 3.2, and outer expansion sleeve 3 and interior expansion sleeve 6 pass through adjusting screw 4 by worm shaft 25 and synchro-nizing universal coupling with ball and sacker 2 swellings.
Worm shaft in fore side screw-down 1 with depress motor direct connection, worm screw 25 axles in back flow side screw-down are by this coupling transferring power, and require two worm shafts to have very high synchronization accuracy.Because multi-roll straightening machine is when correcting strip, require the parallelism of upper and lower work roll very high, the parallelism between upper and lower work roll by the inspection of highi degree of accuracy leveling ruler, adjust its parallelism error≤0.03mm.When this coupling of dress, fore side worm shaft 1 and back flow side worm shaft 25 all can not have any rotation.Because wherein to rotate and will cause upper roller system work roll and lower roll be the not parallel of work roll to any worm shaft, make rectified strip occur the flatness defects such as Bian Lang.
The present invention can realize the Synchronous Transmission between the diaxon of certain drift angle, outer expansion sleeve 3 and interior expansion sleeve 6 can be locked synchro-nizing universal coupling with ball and sacker 2 and worm shaft 25, unclamp quickly and easily by adjusting screw 4, during these Combined coupler mounting or dismounting, the worm shaft of fore side and back flow side does not need any rotation.
