Abstract
The utility model discloses an electric ring chain hoist with a bearing type planetary mechanism which is used for lifting objects in building and installation engineering. The dynamic force of a motor 1 is slowed down by a bearing type planetary mechanism and is sent to a floating coupling brake disc 9 by a drive pin 6 which is provided with a load balancing lining ring 7; the floating coupling brake disc 9 is arranged on an input axis 19 which is screwed on a ring chain hoist 14; thus, the ring chain hoist 14 which is driven drives a hoisting chain 13 to lift and fall or to support objects. The utility model has the advantages of high transmission efficiency, small drive power, simple structure, convenient maintenance and repair, small volume, light weight, safe and reliable operation, and low cost.
Description
The utility model is the bont in a kind of building installation engineering, belongs to the construction hoisting machinery technical field.
Existing electric chain hoist is all with multistage fixed axis gear transmission, and because of its step of reduction is many, the power transmission route is long, thereby total driving efficiency is low, deceleration transmission section construction complexity, fault rate height, manufacturing, inconvenient maintenance, and machine volume is big, mounting or dismounting displacement inconvenience, productive costs height.
The purpose of this utility model then is the problem at above-mentioned existence, and a kind of driving efficiency height is provided, simple structure, and volume is little, and is in light weight, and is easy to make, keep in repair cheap bearing-type planetary mechanism electric chain hoist.
The purpose of this utility model can reach by following measure:
A kind of bearing-type planetary mechanism electric chain hoist, mainly by electrical motor 1, housing 10, bearing-type planetary mechanism 4, trundle 6, all carry lining ring 7, unsteady coupling/brake dish 9, loop chain cucurbit 14 constitutes, and it is characterized in that bearing-type planetary mechanism 4 is connected with housing 10 by fitted outside flat key 5, housing 10 usefulness bolts secondary 11 are connected with the right wallboard 22 of loop chain cucurbit 14, and usefulness bolt pair 3 is connected with electrical motor 1.
The utility model has following advantage compared to existing technology:
Simple in structure, easily manufactured, volume is little, and is in light weight, and productive costs is low, and safety of operation is reliable, and it is low to consume energy, and can be widely used in building installation engineering, is a kind of comparatively ideal energy-saving, integrated-type dead slow speed electric chain hoist.
Fig. 1 is a cutaway view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1: casing 10 usefulness bolt pairs 3,11 respectively with electrical motor 1, the right wallboard 22 of loop chain cucurbit 14 is connected, the output shaft 15 of electrical motor 1 is connected with the center gear of bearing-type planetary mechanism 4 16 usefulness flat keys 2, the outer ring 18 of bearing-type planetary mechanism 4 is connected with casing 10 usefulness fitted outside flat keys 5, the pinion carrier 17 of bearing-type planetary mechanism 4 is connected by several trundles 6 with unsteady coupling/brake dish 9, the left end of trundle 6 is equipped with and all carries lining ring 7, the left-handed multiple screw thread that floats on the input shaft 19 of coupling/brake dish 9 and loop chain cucurbit 14 screws mutually, ratchet 12 is fixed on the right wallboard 22, can stop ratchet 21 dextrorotation to be rotated.
When promoting article, electrical motor 1 at high speed dextrorotation is rotated, after its power increases square by 4 decelerations of bearing-type planetary mechanism, rotate with low speed dextrorotation by pinion carrier 17, and drive the coupling/brake dish 9 that floats by trundle 6 and on input shaft 19, withdraw from until spacing by nut 8, then with input shaft 19 to rotate with fast dextrorotation, so ratchet 21 rotates with unsteady coupling/brake dish 9 with input shaft 19, thereby make loop chain cucurbit 14 drive lifting chain 13 and promote article, trundle 6 is interference fit with the lining ring of being made by elastomeric material 7 that all carries, if when trundle 6 unbalance stress occurring in the transmission, all carry lining ring 7 and be out of shape thereupon, thereby make each trundle 6 stressed even; When supporting article to rest on when aerial, the gravity that acts on the lifting chain 13 makes input shaft 19 left-handed rotations by loop chain cucurbit 14, drive the coupling/brake dish 9 that floats and compress brake strip 20, ratchet 21 was blocked and can not rotate by ratchet 12 this moment, so loop chain cucurbit 14 is braking mode, can support that article rest in the air.When the decline article, the left-handed running of electrical motor 1 at high speed, pinion carrier 17 is with the left-handed rotation of low speed, driving the coupling/brake dish 9 that floats by trundle 6 rotates and take-off the brake friction lining 20, this moment, ratchet 12 blocked ratchet 21, so brake strip 20, ratchet 21 do not rotate, and input shaft 19 is done left-handed rotation with unsteady shaft coupling system dish 9 with trundle 6, makes loop chain cucurbit 14 drive lifting chain 13 decline article.
