Abstract
The utility model provides an encoder insulation system for hauler, belong to the manufacturing technical field of hauler in the elevator system, establish hauler frame (1) of pivot (9) and bearing (2) in mainly by establishing, arrange enclosing cover (7) behind the bearing of hauler frame (1) terminal surface in, arrange encoder (3) in enclosing cover (7) behind the bearing in, arrange pivot (9) and bearing behind enclosing cover (7) in and the insulating cover of the axle (5) and bearing rear cover end cover (6) that correspond the position of encoder (3) in, arrange copper inserts (4) etc. in the insulating cover of axle (5) in. The utility model relates to a rationally, compact structure, through with insulating material axle insulation cover and bearing back enclosing cover pot head insulating with encoder contact department, stop the influence to encoder feedback signal such as electric field, magnetic field, ensure that feedback signal is accurate, also make the motor under the not good condition of ground connection, still can normal operating, can prolong hauler and encoder life-span.
Description
Technical field
The utility model relates to a kind of towing machine coder insulation system, belongs to the manufacturing technology field of towing machine in the elevator device.
Background technology
The towing machine that uses in the existing elevator device generally is installed on machine room or is directly installed on the hoistway.Elevator is all just installed by elevator producer after the completion of building basic structure.And unit in charge of construction is very few to the mounting condition understanding of towing machine, not understands even.In concrete work progress, be easy to occur the bad or electric wire of ground connection and arrange a series of problems that influence the correct feedback signal of coder such as the space is unreasonable, make normally smooth operation of towing machine.Simultaneously, can produce a large amount of heats during the towing machine operation, these heats outwards distribute by parts such as supports.If coder installation place naked structure, these heats will make the coder temperature build-up by media such as enclosing covers behind rotating shaft, the bearing, influence the life-span of coder.When environmental problem was also very high, being heated to cause trickle distortion, so also can influence the precision of encoder feedback signal.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and compact conformation can prolong towing machine and the towing machine in coder life-span coder insulation system.
The utility model is a towing machine coder insulation system, establish the towing machine support of rotating shaft and bearing in comprising, place enclosing cover behind the bearing of towing machine support end face, place the coder in the enclosing cover behind the bearing, it is characterized in that behind rotating shaft and the bearing in the enclosing cover that correspondence position with coder is respectively equipped with enclosing cover end cover behind an insulation sleeve and the bearing, coder is fixed on the insulation sleeve.
Also can be provided with copper insert in the described axle insulation sleeve, antirust and prevent the stripped thread effect with further raising.
Described axle insulation sleeve can be captiveed joint with rotating shaft with screw.
The utility model is reasonable in design, and compact conformation by enclosing cover end cover insulation after using insulating material axle insulation sleeve and bearing with the coder contact position, is stopped the influence to the encoder feedback signal such as electric field, magnetic field, guarantees that feedback signal is accurate.Also make motor under the bad situation of ground connection, still can normally move.The towing machine operation noise of this kind structure is also than about the low 10dB of coder installation place naked structure towing machine operation noise.Can prolong towing machine and coder life-span.
Description of drawings
Accompanying drawing is integral structure of the present utility model and part sectional view.
The specific embodiment
The utility model is mainly by the interior towing machine support 1 of establishing rotating shaft 9 and bearing 2, place enclosing cover 7 behind the bearing of towing machine support 1 end face, place the coder 3 in the enclosing cover 7 behind the bearing, place behind rotating shaft 9 and the bearing in the enclosing cover 7 with the axle insulation sleeve 5 of coder 3 correspondence positions and bearing after enclosing cover end cover 6, place copper insert 4 formations such as grade in the insulation sleeve 5.Coder 3 is fixed on the insulation sleeve 5, and axle insulation sleeve 5 usefulness screws 8 are captiveed joint with rotating shaft 9.
Be fitting surface with axle insulation sleeve 5 maximum outside diameters during installation, an axle insulation sleeve 5 is pressed in the rotating shaft 9, with screw 8 insulation sleeve 5 is fixed in the rotating shaft 9 again, make both mechanical connections more firm.
Enclosing cover 7 mainly is that enclosing cover 7 mechanical strengths will be got well after this just required bearing, generally all adopted metallic material for protection coder and regular coding device in processes such as towing machine transportation behind the bearing.It and support get up by screw retention, in order to allow coder 3 insulation, enclosing cover insulating end cover 6 behind fixed type bearing on the enclosing cover behind the bearing 7.
Earlier enclosing cover end behind the bearing is overlapped 6 during installation and be fixed to behind the bearing on the enclosing cover 7, again coder 3 is fixed on the insulation sleeve 5, then enclosing cover behind the bearing 7 is fixed on the towing machine support 1.
Towing machine is installed on machine room or is directly installed on the hoistway, the space is very little, be easy to occur the bad or electric wire of ground connection and arrange problems such as the space is unreasonable, adopt said structure can stop the influence to the encoder feedback signal such as electric field, magnetic field, make feedback signal accurate, prolong towing machine and coder life-span.
Claims (3)
1, a kind of towing machine coder insulation system, establish the towing machine support (1) of rotating shaft (9) and bearing (2) in comprising, place enclosing cover (7) behind the bearing of towing machine support (1) end face, place the coder (3) in the enclosing cover (7) behind the bearing, it is characterized in that behind rotating shaft (9) and the bearing in the enclosing cover (7) that correspondence position with coder (3) is respectively equipped with enclosing cover end cover (6) behind an insulation sleeve (5) and the bearing, coder (3) is fixed on the insulation sleeve (5).
2,, it is characterized in that also being provided with copper insert (4) in the described axle insulation sleeve (5) by the described towing machine of claim 1 coder insulation system.
3,, it is characterized in that described axle insulation sleeve (5) usefulness screw (8) captives joint with rotating shaft (9) by the described towing machine of claim 1 coder insulation system.
