Abstract
The utility model relates to a speed reducing mechanism for a hand-driven ring-chain hoist, which is characterized in that a fixing inner gear is coaxially connected with a hoisting chain wheel and a left plate through a supporting rod; an oscillating tooth frame is coaxially connected with the hoisting chain wheel; a straight groove on the radial circumference of the oscillating tooth frame is glidingly matched with oscillating teeth and an oscillating wheel bracket. A needle bearing is connected with the dual eccentricity end of an input shaft; the input shaft is inserted into a hole of the hoisting chain wheel; an outer ring of the needle bearing is glidingly matched with the oscillating teeth and the oscillating tooth bracket. When weight is lifted, a hand-driven chain wheel can be pulled by a hand-driven chain to drive the input shaft and the needle bearing to rotate following; the oscillating tooth bracket and one end of each oscillating tooth can move along an outer circle rollaway nest of the needle bearing. Because teeth of the fixing inner gear is one more than teeth of oscillating teeth, the oscillating tooth bracket can push the oscillating tooth frame to turn reversely with ne tooth for reducing speed through a radial straight hole wall, when the input shaft rotates a circle. The utility model has the advantages of high capability, high efficiency, high safety, low cost, etc.
Description
One, technical field:
The utility model relates to manual loop chain cucurbit speed reduction gearing, the movable tooth drive mechanism of specifically a kind of manual loop chain cucurbit.
Two, technical background:
The speed reduction gearing of at present existing all kinds of manual loop chain cucurbits slows down with multistage fixed axis gear transmission, and drive path long pass efficiency of movement is low, complex structure, fault rate height.Weight promotes or descends and all adopts ratchet, ratchet, and the brake mode of Friction disk is owing to ratchet, ratchet, Friction disk inefficacy easy to wear, shortcomings such as poor stability.、
Three, summary of the invention:
At the shortcoming that above-mentioned now all kinds of manual loop chain cucurbits exist, the utility model provides a kind of one-level rolling free gear engaged transmission, load-carrying capacity big, the efficient height, and have the movable tooth drive mechanism of the good manual loop chain cucurbit of self locking safety performance.The utility model movable tooth drive mechanism, the similar cycloidal-pin wheel transmission of structural principle, and no-output mechanism, mainly by fixed annulus, oscillating tooth carrier, oscillating tooth, the oscillating tooth holder, needle bearing, input shaft, chain hoist wheel, compositions such as left side board, it is characterized in that fixed annulus (1) and chain hoist wheel (7), left side board (10) the coaxial connection of strut bar (12), oscillating tooth carrier (2) and coaxial connection of chain hoist wheel (7), the circumference of oscillating tooth carrier (2) is straight trough and oscillating tooth (3) radially, oscillating tooth holder (4) bearing fit, the two eccentric end of input shaft (6) are connected with needle bearing (5), input shaft (6) inserts in chain hoist wheel (7) hole, needle bearing (5) periphery and oscillating tooth holder (4), oscillating tooth (3) bearing fit connects into the movable tooth drive mechanism of manual loop chain cucurbit by case (8) and backplate (9).Its role is to oscillating tooth (3) and arrange the eccentric input shaft of double-bank by 180 degree, motion steadily, total number of teeth in engagement is many, load-carrying capacity is big, and when the lifting weight stopped, oscillating tooth carrier (2) was because of the antagonistic force of weight generation simultaneously, force oscillating tooth (3), oscillating tooth holder (4) generation of double 180 ° of arrangements to apply symmetrical pressure toward input shaft, locked input shaft reaches self-locking, and weight can not descended voluntarily, has guaranteed safety.Advantage of the present utility model: the eccentric 180 ° of symmetries of input make stable drive; The many load-carrying capacitys of movable tooth drive mechanism total number of teeth in engagement are big, and speed ratio is big, the efficient height; Save the transmission device of original ratchet, ratchet Friction disk, simple in structure, low cost of manufacture; It is good to have the auto-lock function safety performance.
Four, description of drawings:
Fig. 1 looks intention for the structure of the movable tooth drive mechanism of manual loop chain cucurbit of the present utility model.
Among the figure: 1, fixed annulus; 2, oscillating tooth carrier; 3, oscillating tooth; 4, oscillating tooth holder; 5, needle bearing; 6, input shaft; 7, chain hoist wheel; 8, case; 9, backplate; 10, left side board; 11, pull sprocket wheel; 12, strut bar; 13, nut; 14, suspension hook;
Fig. 1 illustrates: fixed annulus (1) is for the circular arc inner gear of cycloidal curve, be connected with chain hoist wheel (7), left side board (10), strut bar (12), nut (13), concentric; Oscillating tooth carrier (2), with chain hoist wheel (7), coaxially be connected,, oscillating tooth carrier (2), with oscillating tooth holder (4), oscillating tooth (3) bearing fit; Input shaft (6) is two eccentric integral structures and needle bearing (5), chain hoist wheel (7) bearing fit; Needle bearing (5) outer ring and oscillating tooth holder (4), oscillating tooth (3) bearing fit; By case (8) and backplate (9), pull the movable tooth drive mechanism that sprocket wheel (11), suspension hook (14) connect into the hand draw ring chain block.
Five, the specific embodiment:
Below in conjunction with Fig. 1 implementation process of the present utility model is described further:
When promoting weight, pull sprocket wheel and drive input shaft (6) and needle bearing (5) by pulling chain pulling also along with rotation, one end of oscillating tooth holder (4) and oscillating tooth (3) is along the cup raceway motion of needle bearing (5), the radially straight hole crank motion on the oscillating tooth carrier (2) simultaneously, the many teeth of ratio of number of teeth oscillating tooth (3) because of its fixed annulus (1), therefore when input shaft (6) rotates a week, oscillating tooth (3), oscillating tooth holder (4) promotes oscillating tooth carrier (2) by the radially straight hole wall on the oscillating tooth carrier (2) and oppositely turns over a tooth, reach the deceleration purpose, because of oscillating tooth carrier (2) and coaxial connection of chain hoist wheel (7), promptly promote weight; When the lifting weight stops, because the antagonistic force of weight, force oscillating tooth (3), oscillating tooth holder (4) to produce symmetrical pressure by fixed annulus (1) and double eccentric 180 ° of symmetric offset spread needle bearings (5), reach self-locking and braking, weight does not descend, when reverse pulling pulls the sprocket wheel answer that promptly descends.
Claims (2)
1, the movable tooth drive mechanism of a kind of manual loop chain cucurbit, comprise fixed gear wheel, oscillating tooth carrier, oscillating tooth, the oscillating tooth holder, needle bearing, input shaft, chain hoist wheel, left side board, it is characterized in that fixed annulus (1) and chain hoist wheel (7), left side board (10) the coaxial connection of strut bar (12), oscillating tooth carrier (2) and coaxial connection of chain hoist wheel (7), the circumference of oscillating tooth carrier (2) is straight trough and oscillating tooth (3) radially, oscillating tooth holder (4) bearing fit, the two eccentric end of input shaft (6) are connected with needle bearing (5), input shaft (6) inserts in chain hoist wheel (7) hole, needle bearing (5) outer ring and oscillating tooth holder (4), oscillating tooth (3) bearing fit.
