Abstract
The utility model discloses a four-stage driving device for a single-chain block, relating to an important component for a transmission mechanism of a chain block. The structural characteristics of four-stage driving device for the single-chain block is that a the toothed edge on the right end of a nine teeth long axle (5) is engaged with the toothed edge of an I-stage driven gear (6), II-stage driving gear (7) is engaged with II-stage driven gear (3), an idler gear (4) is engaged with a piece gear (1), and a five teeth stub axle (2) is engaged with a splined hole gear (8). The parts are all arranged between an external wall board (9) and a left wall board (10) to form a four-stage driving device. With the integral structure of the four-stage device being compact, each part stressing uniformly, and the integrative drive being comparatively big, the lifting force of the chain block is greatly reduced; a chain block whose weight is 3-5 ton can adopt a single chain structure, the weight of the complete machine is greatly reduced, the volume is reduced, the structure of the chain block is simplified, the production cost is lowered, and the purposes of simple structure and labour saving are obtained.
Description
One, technical field:
The level Four driving device of the novel strand chain block of the utility model is a kind of transmission device that is used for chain block, is the vitals of strand chain block.
Two, background technology:
At present, the 3-5 ton chain block of domestic production all adopts double-stranded secondary transmission device, because messenger chain is short only little through the two stage speed change transmitting ratio, cause bigger hand in hand, double-stranded increase a chain and other annex than strand become complicated, volume of structure is increased, be difficult to reach use simple in structure labour-saving purpose.
Three, summary of the invention:
At above-mentioned existing problems, adopt double-stranded secondary transmission device to have defective for overcoming prior art, the utility model provides a kind of level Four driving device of strand chain block.
The level Four driving device of the utility model strand chain block: comprise plate gear (1), five tooth minor axises (2), II level driven gear (3), free gear (4), nine tooth major axis (5), I level driven gear (6), II level driving gear (7), splined hole gear (8), Side fascia (9), right wallboard (10), chain hoist wheel (11) composition, its technical characterictic is that the correct engagement of nine tooth major axis (5) right gear portions and I level driven gear (6) tooth portion constitutes 1 grade of transmission; I level driven gear (6) is coaxial with II level driving gear (7), makes the correct engagement of II level driving gear and II level driven gear (3), becomes 2 grades of transmissions by 1 grade of transmission; II level driven gear (3) is coaxial with free gear (4), makes free gear (4) and 3 grades of transmissions of plate gear (1) correct engagement structure; Plate gear (1) is coaxial with five tooth minor axises (2), and five tooth minor axises are by constituting the level Four transmission with splined hole gear (8) correct engagement; Each parts of level Four transmission are installed in the level Four driving device that becomes a strand chain block between Side fascia (9) and the right wallboard (10).The utility model advantage is: (one) is because the design of this four-stage device is ingenious, compact overall structure, each is partly stressed even, has load-carrying capacity preferably, and (two) transmission makes comprehensive transmitting ratio bigger through level Four, greatly reduce the chain block lifting power, make 3-5 ton chain block all can adopt single-stranded structure, the extremely big overall weight that reduces has been dwindled volume, simplify the structure of cucurbit, reduced productive costs.
Four, description of drawings:
Fig. 1 is the level Four transmission structures figure of chain block.
Among the figure: 1, plate gear, 2, five tooth minor axises, 3, II level driven gear, 4, free gear, 5, nine tooth major axis, 6, I level driven gear, 7, II level driving gear, 8, the splined hole gear, 9, Side fascia, 10, right wallboard, 11, chain hoist wheel.Illustrate: nine tooth major axis (5) are in the center in the middle of being installed in chain hoist wheel, nine tooth major axis and II level driving gear, II level driving gear and II level driven gear, free gear and plate gear, five teeth are short in meshing respectively with the splined hole wheel, constitute the level Four drive mechanism.。
Five, the specific embodiment:
In conjunction with Fig. 1, the utility model implementation process is described further:
Installation process at first: the bearing on chain hoist wheel and the right wallboard is closely cooperated; Respectively by press plate gear (1), II level driven gear (3), I level driven gear (6) is pressed into five tooth minor axises (2), free gear (4), II level driving gear (7) constitutes each parts, by major axis the free gear (4) after press-fiting is gone here and there together with chain hoist wheel (11), respectively five tooth minor axises (2) after press-fiting and II level driving gear (7) the right wallboard (10) of packing into is gone up in the corresponding steel bushing, make nine tooth major axis (5) and driving gear (7), II level driving gear (7) and II level driven gear (3), free gear (4) and plate gear (1), five tooth minor axises (2) mesh respectively with pattern chain hole tooth (8); The outer body of wall of assembling (9) is fixed each partly position at last; Use: pass through nine tooth major axis (5) and I level driven gear (6) during use, II level driving gear (7) and II level driven gear (3), free gear (4) and plate gear (1), five tooth minor axises (2) really mesh the bigger transmitting ratio of generation with the difference sky of splined hole gear (8), produce higher driving efficiency, make the operator with the less power that pulls hoisting heavy; Make operator's weight that easily descends by what above-mentioned route back transfer caused than big speed ratio during decline.
Claims (2)
1, a kind of level Four driving device of strand chain block, mainly comprise compositions such as plate gear, five tooth minor axises, nine tooth major axis, II level driving gear, splined hole gear, chain hoist wheel, wallboard, its technical characterictic is nine tooth long sleeves (5) right gear portions and the engagement of I level driven gear (6) tooth portion, II level driving gear (7) and II level driven gear (3) engagement, free gear (4) and plate gear (1) engagement, five tooth cottas (2) by with splined hole gear (8) engagement, more than each parts be installed between left wallboard (10) and the Side fascia (9).
2, according to the level Four driving device of claims 1, described each part engagement features is I level driven gear (6) and II level driving gear (7); II level driven gear (3) and free gear (4); Plate gear (1) is respectively a coaxial relation with five gear wheel shafts (2).
