Abstract
The utility model discloses a chain hoist which comprises a few-tooth-difference speed reducer and a hoist body, wherein the center shaft of the hoist body and the few-tooth-difference speed reducer are connected to drive a hoist body chain wheel. The chain hoist has the advantages as follows: a small-modulus and small-diameter gear of a planetary reducer is absent, and stress of an eccentric bearing is smaller than that of a cycloidal pin gear speed reducer, therefore, the chain hoist is long in service life, low in cost and safe and reliable to work.
Description
Technical field
The utility model relates to a kind of ring-chain hoist.
Background technology
Slowly rising ring-chain hoist has the ring-chain hoist of planetary reducer and the ring-chain hoist of cycloidal pin reductor at present, the reducer gear modulus of planetary reducer ring-chain hoist is little, tooth is not durable, outside diameter of gear small-bore small axle diameter is also little, between axis hole, can not execute bearing, and hole axle can wear and tear, axle is easy to break, the reductor capacity eccentric bearing of cycloidal pin reductor ring-chain hoist is stressed large, and part tooling cost is high, and cycloidal-pin wheel material valency is high.
Utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of low cost of manufacture, long service life, safe and reliable ring-chain hoist.
The technical solution adopted in the utility model is:
A ring-chain hoist, comprises few teeth difference reductor and cucurbit body, and cucurbit body center shaft is connected driving cucurbit sprocket body with few teeth difference reductor.
Further, described few teeth difference reductor mainly consists of internally toothed annulus, satellite gear, eccentric bushing, motor shaft, capacity eccentric bearing, concentric bearings, motor bearings, plain thrust bearing, bearing pin guide, pin dish, input magazine motor body, delivery casing and motor stator, and input magazine motor body, internally toothed annulus and delivery casing form few teeth difference and slow down
The shell of machine, assemble with input magazine motor body, delivery casing seam respectively at internally toothed annulus two ends, motor stator is installed in the external end face of input magazine motor, motor shaft is assemblied in the assembly opening of input magazine motor body by motor bearings and concentric bearings, eccentric bushing is socketed on motor shaft, and eccentric bushing has two contrary bias of relative motor shaft axis direction, and two bias drive two satellite gears by capacity eccentric bearing, two satellite gears and internally toothed annulus engagement, pin dish is connected with satellite gear by bearing pin guide.
Further, between described pin dish and delivery casing, be equipped with self-lubricating bearing.
Further, described cucurbit body comprises cucurbit body center shaft, cucurbit body header board, cucurbit sprocket body and sprocket shaft bearing, cucurbit body header board is connected with delivery casing seam, cucurbit body center shaft one end is connected with pin dish, the other end is assemblied in the hole on cucurbit body header board by sprocket shaft bearing, and is connected with cucurbit sprocket body.
The utility model has the advantage of: there is no the little modulus small diameter gear of planetary reducer, capacity eccentric bearing is stressed large less than cycloidal planetary gear speed reducer, so this ring-chain hoist life-span is long, cost is low, safe and reliable.

The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of ring-chain hoist, comprise few teeth difference reductor and cucurbit body, described few teeth difference reductor is mainly by internally toothed annulus 1, satellite gear 2, eccentric bushing 3, motor shaft 4, capacity eccentric bearing 5, concentric bearings 6, motor bearings 7, plain thrust bearing, bearing pin guide 9, pin dish 10, input magazine motor body 11, delivery casing
12 and motor stator 20 form, input magazine motor body 11, internally toothed annulus 1 and delivery casing 12 form the shell of few teeth difference reductor, internally toothed annulus 1 two ends respectively with input magazine motor body 11, delivery casing 12 seam assemblings, motor stator 20 is installed in input magazine motor body 11 outer faces, motor shaft 4 is assemblied in the assembly opening of input magazine motor body 11 by motor bearings 7 and concentric bearings 6, eccentric bushing 3 is socketed on motor shaft 4, eccentric bushing 3 has two contrary bias of relative motor shaft 4 axis directions, two bias drive two satellite gears 2 by capacity eccentric bearing 5, two satellite gears 2 mesh with internally toothed annulus 1, pin dish 10 is connected with satellite gear 2 by bearing pin guide 9.Between described pin dish 10 and delivery casing 12, be equipped with self-lubricating bearing 16.
Described cucurbit body comprises cucurbit body center shaft 14, cucurbit body header board 15, cucurbit sprocket body 18 and sprocket shaft bearing 19, cucurbit body header board 15 is connected with delivery casing 12 seams, cucurbit body center shaft 14 one end are connected with pin dish 10, the other end is assemblied in the hole on cucurbit body header board 15 by sprocket shaft bearing 19, and is connected with cucurbit sprocket body 18.
When work, motor shaft 4 and eccentric bushing 3 rotations make two satellite gears 2 and internally toothed annulus 1 engaged transmission, two satellite gears 2 produce capacity eccentric bearing 5 rotations around separately, with the axle center revolution around internally toothed annulus 1, the revolution of two satellite gears 2 is rotated by bearing pin guide 9 band untie-sell dishes 10, pin dish 10 drives again cucurbit body center shaft 14, and cucurbit body center shaft 14, by the reductor deceleration cucurbit sprocket body 18 of cucurbit body, completes the transmission of whole ring-chain hoist.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,
All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
