Abstract
The utility model relates to a cantilever wheel type planetary gear traction engine which is composed of two stages of planetary gear speed reducers, a traction wheel 12, an engine block 1 and a friction type electromagnetic brake, both a first-stage planetary gear and a second-stage planetary gear adopt helical gear structures, both ends of inner holes of an inner gear ring bracket 14 are respectively meshed with a first-stage inner gear ring 8 and a second-stage inner gear ring 15, and an outer ring is inserted into a cantilever type gear box shell 16 and endures loads at one end connected with the engine block 1, which causes that the traction wheel 12 and the gear box shell 16 can rotate in positive and negative directions. The utility model has the advantages of small size, light weight, high efficiency, low noise, high machining accuracy and simple assembly. A single-point support is adopted.
Description
The utility model relates to a kind of wheeled planetary wheel towing machine of cantilever of elevator special use.
The towing machine of elevator use at present generally is the worm-and-wheel towing machine.Need two point to support when this class towing machine is installed, volume is big, weight is big, efficient is low.
The purpose of this utility model just provides the wheeled planetary wheel towing machine of cantilever that a kind of single-point supports, volume is little, in light weight, efficient is high, noise is little.
Solution of the present utility model is such: by secondary planetary gear retarder, traction sheave 12, body 1, friction-type magnet stopper; Form the utility model.Have in it and body 1 bonded assembly internally toothed annulus carriage 14, mesh with one-level internally toothed annulus 8, secondary internally toothed annulus 15 respectively at internally toothed annulus carriage 14 endoporus two ends, its outer ring is inserted in the cantilevered gear-box case and is being born load with body 1 coupling end, one section inoperative position that one-level internally toothed annulus 8 stretches out in the internally toothed annulus carriage 14 links to each other with body 1 location, thereby shortened the axial dimension of epicyclic gear box greatly, make two shaft strengths of cantilever structure more even rationally with load, make it to realize the structure of single-point support, only body 1 need be fixed and just can work.
The utility model has the advantages that single-point supports, volume is little, in light weight, efficient is high, noise is little, working accuracy is high, assembling is simple.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model A-A cutaway views.
Accompanying drawing 3 is deceleration principle schematic.
The utility model is by the secondary planetary gear retarder, traction sheave 12, body 1, friction-type magnet stopper are formed, have in it and body 1 bonded assembly internally toothed annulus carriage 14, internally toothed annulus carriage 14 endoporus two ends respectively with the one-level internally toothed annulus 8 of sun and planet gear, the engagement of secondary internally toothed annulus 15 keys, its outer ring insert in cantilevered gear-box case 16 and with body 1 coupling end with being loaded; One section inoperative position that one-level internally toothed annulus 8 stretches out in the internally toothed annulus carriage 14 links to each other with body 1 location.One end and the traction sheave 12 of cantilevered gear-box case 16 are fastening, and bearing pre-tightened is fixed by radial seal assembly 10, utilize bearing to bear the load of traction sheave 12, the other end and secondary planet assembly 17 are fastening, thereby traction sheave 12 and gear-box case 16 can be rotated by both forward and reverse directions, finish takeoff output by traction sheave 12.
Because the special construction of internally toothed annulus carriage 14, making one-level internally toothed annulus 8, secondary internally toothed annulus 15 is to stretch into from the both sides of internally toothed annulus carriage respectively and 14 engagements of internally toothed annulus carriage.Bearing seat 6 left sides have the datum hole of seam and body 1 to locate fastening and withstand one-level internally toothed annulus 8 location.First planetary wheel is come under the unsteady situation to be meshed with input shaft, internally toothed annulus.It is to be connected with several bolts M that body 1 is connected with one-level internally toothed annulus carriage 14, one is band nut counter sink between several bolts hole of opening on the body 1 are adjacent, (as accompanying drawing 1 upper bolt hole), another is not for being with nut counter sink (as accompanying drawing 1 lower bolt hole), be not with the nut counter sink consistent with mounting hole on the bearing seat 6, with overbolt M that body 1, one-level internally toothed annulus carriage 14 and bearing seat 6 is fastening, lag bolt M is only fastening with internally toothed annulus carriage 14 and body 1.
For reducing mechanicalness noise, be provided with sound insulation vibration damping retaining rubber lacquer disk(-sc) 7 and sound-absorbing damping circle 11 at the two ends of one-level internally toothed annulus 8, in the middle of the sound insulation vibration damping retaining rubber disc 7 position, tapering, garden of holes, garden and input shaft 2 near, formation sound-absorbing barrier plays vibration isolation, damping, noise reduction effect.The outside face that inserts in the cantilevered gear-box case 16 at internally toothed annulus carriage 14 is provided with the absorbing sound and lowering noise pitch prill, to absorb the gear transmission noise that internally toothed annulus 15 reaches carriage 14.
Magnet stopper is to be made of input gear axle 2, magnet stopper 3, braking asbestos friction dish 5, is with two groups of O type circles 4 between the spline radial fit of braking asbestos friction dish 5 and input gear axle 2.
The stage casing of body 1 is an octagon, and both ends of the surface garden arc design makes that body is 1 in light weight, intensity is high, it is generous to have attractive appearance.
In the present embodiment, O type circle is installed at one-level internally toothed annulus 8 inoperative positions.The I and II planetary wheel all adopts the helical wheel structure.
