Description
The utility model belongs to weight-lifting equipment and relates to a kind of nutating deceleration Electric Chain Blocks.
The Electric Chain Blocks of producing both at home and abroad adopts secondary or three grades of fixed axis gear speed reduction gearings, mostly though can satisfy the requirement of various lifting operations at present, exist the structure heaviness in various degree, part is many, and volume and weight is bigger than normal, and processing and manufacturing cost problem of higher.The Electric Chain Blocks made of introduction of foreign technology particularly, adopt aluminum alloy die-casting technological, need equipment investments such as particular manufacturing craft investment and machining center higher, make its price be higher than the steel-wire rope type electric block of identical hoisting capacity for many years, influence the development of Electric Chain Blocks.
The purpose of this utility model is to overcome the deficiencies in the prior art, and the theoretical design-calculated nutating of a kind of application nutating deceleration Electric Chain Blocks is provided.Can not only satisfy the requirement of various lifting operations, and have simple in structurely, part is few, and volume is little, and lightweight advantage reaches purpose of high quality and at a reasonable price.
The utility model is achieved through the following technical solutions: a kind of nutating deceleration Electric Chain Blocks, comprise band brake motor, boatswain chair, erecting by overhang, lead chain inhibiting device and electric control system.Described speed reduction gearing is the nutating retarder, and overload protection clutches is equipped with in portion within it.The nutating retarder is by the finishing bevel gear cuter (4) of the relative ingear band of coaxial line hollow shaft, form with nutation cone gear (7), the nutating producer edge type strainer (9) that is loaded on nutation cone gear (7) back and circumferential locating pair (17).Nutating producer edge type strainer (9) is loaded on the input shaft (12), and the rotation axis of its cam spigot surface becomes a slanted angle with input shaft (12) axis.Described overload protection clutches is made up of clutch sleeve (13) that is loaded on edge type strainer (9) endoporus and the adjustment nut (14) that is loaded on edge type strainer (9) positive friction lining (10), tie-plate (11), disk spring (16) and is loaded on edge type strainer (9) back side; clutch sleeve (13) one ends have boss to block disk spring (16), and the other end has screw thread to connect adjustment nut (14).Described lead the chain inhibiting device by last chain guides (24) and be loaded on 2 travel switches (26) of its underpart, down lead carrier bar (25), limit lever (18), lead chain case (19) and coupled coil spring (20) is formed.Motor (1) links to each other with input shaft (12) by flat key muff coupling (5), and sprocket wheel (23) is loaded on the hollow shaft of hollow shaft finishing bevel gear cuter (4).
It is little, in light weight that the utility model not only has a volume, the few and low advantage of tooling cost of part, and output mechanism generally small Tooth Number Difference Planetary Transmission is simple.Ingear tooth logarithm can reach more than 10% of full-depth tooth number simultaneously, and load-carrying capacity can improve 1-3 doubly.So, just can reduce to gear material the requirement of heat treatment and working accuracy.Reduce raw MAT'L and tooling cost, price also can reduce, and realizes that price is lower than the target of identical hoisting capacity steel-wire rope type electric block.
Be described further below in conjunction with embodiment of the present utility model.
Description of drawings:
Fig. 1-the utility model structure cutaway view.
Fig. 2-the utility model is led chain inhibiting device part-structure figure.
(1) motor, (2) boatswain chair, (3) upper lift ring, (4) hollow shaft finishing bevel gear cuter, (5) flat key muff coupling, (6) reducing gearbox, (7) nutation cone gear, (8) bearing, (9) nutating producer edge type strainer, (10) friction lining, (11) tie-plate, (12) input shaft, (13) safety clutch cover, (14) adjustment nut, (15) pad, (16) disk spring, (17) are locating pair circumferentially, (18) limit lever, (19) lead chain case, (20) lead the chain spring, (21) suspension hook assembly, (22) chain, (23) sprocket wheel, (24) go up chain guides, lead carrier bar under (25), (26) travel switch, (27) boatswain chair tie bolt.
Fig. 1, Fig. 2 show an embodiment of the present utility model.The outgoing side of motor (1) connects boatswain chair (2), it is an integral body that the left end flange of reducer shell (6) is connected with 4 bolts (27) with boatswain chair (2), motor (1), sprocket wheel (23), upper lift ring (3) and erecting by overhang is installed between boatswain chair (2) and motor flange and is led the chain inhibiting device.The output shaft of motor (1) links to each other by flat key muff coupling (5) with input shaft (12), and passes from hollow shaft finishing bevel gear cuter (4) interstitial hole.Input shaft (12) cooperates with nutating producer edge type strainer (9) by clutch sleeve (13), and edge type strainer (9) matches with nutation cone gear (7) again through bearing (8).Hollow shaft finishing bevel gear cuter (4) is that outer cone-Ping bores fit form with nutation cone gear (7).2 pairs of circumferential locating pairs (17) are loaded on the inwall of reducer shell (6).
During work, handle motor (1) starting by electric control system, drive input shaft (12) high speed revolution by coupler (5), axle (12) is through clutch sleeve (13), tie-plate (11), and friction lining (10) drives contrite gear (9) rotation.At this moment, be contained in bearing (8) and nutation cone gear (7) on the edge type strainer (9) and be subjected to the constraint of circumferential locating pair (17), can not rotate with edge type strainer (9), oscillating motion can only circulate, and form on-cycle folding engagement with the hollow shaft finishing bevel gear cuter (4) that is contained in coaxial line, the gear teeth that make nutation cone gear (7) along the circumferential direction circulation constantly and hollow shaft finishing bevel gear cuter (4) enter engagement, withdraw from engagement again, the motion of realization side set, thereby drive hollow shaft finishing bevel gear cuter (4) low speed rotation, and drive sprocket wheel (23) and chain (22) and suspension hook assembly (21) realization lifting operation.Lead chain spring (20) when the shelves iron of the baffle plate of suspension hook assembly (21) or chain (22) tail end collides, drive and lead chain case (19) and limit lever (18) promotes travel switch (26), control suspension hook and stop lifting.
In addition; by adjustment nut (14), change the setting pressure of dish spring (16), when external load surpasses 1.5 times of rated loads; produce between tie-plate of safety clutch (11) and friction lining (10) and skid, the safe operation of protection motor, nutation cone gear and chain elevator system.
Embodiment two, and hollow shaft finishing bevel gear cuter (4) is outer cone-outer cone fit form with nutation cone gear (7), and other are identical with embodiment one.
