The utility model has the advantages that the speed ratio is broad, the volume is small, the heat radiating is excellent, the explosion-proof and the waterproof performances are strong, the weight of the whole machine is light, the structure is compact, and the installation is convenient; the utility model is an ideal product for replacing the old type speed reducing machine.

Description

The oil immersed type decelerator

One, affiliated technical field

The utility model relates to a kind of reductor and motor machine, as the power source of inflammable and explosive place and long-term field work.

Two, background technology

At present, slow down this method adopts cylinder gear speed reducer and cycloid clock wheel decelerator to realize; Explosion-proof then is that all the cooperation seam lengthenings and the contact-making surface precision of motor are improved, and is sealed.Stationary part still can solve, and rotating part can't solve at all, and its shortcoming is: 1, motor adds upper reducer and installs in the lump, and volume is big, quality is heavy, installation is inconvenient; 2, in a single day motor burns out suddenly, and spark has the possibility of emerging from rotating part, can not be reliably explosion-proof, and waterproof is also poor; 3, the every change of all rotating speeds once, internal structure must change, machine shell also must change sometimes.

Three, summary of the invention

In order to overcome above-mentioned defective, the utility model provides that a kind of novel energy is explosion-proof, waterproof, speed ratio are wide, changes apart from integrating dynamo-electric decelerator greatly.

The technical scheme of the utility model technical solution problem: 1, deceleration part adopts the principle of twin-stage from the suspension type planetary reduction gear, it is by three planet teeth on the input pinion driving intermediate disc tooth axle, decide to roll on the gear ring in input, intermediate disc tooth axle is rotated; In like manner, drive three output planetary teeth of output disk tooth axle again, decide to roll on the gear ring, then make the output disk axle make low-speed running in output; 2, motor partly is that motor with existing technology is sealed, and fill with insulating oil, also be provided with a sealed terminal box and safety disc, in case occur good spark, electric arc etc. when motor burns out, insulating oil can extinguish it rapidly, expand if oil heats up suddenly, can oil spill be gone into annular seal space by breaking of safety disc and not cause the motor housing blast; 3, owing to integrate dynamo-electric coaxial output, install very convenient.

Useful benefit of the present utility model is: bipolar from the suspension type planetary reduction gear, and compact conformation, it is less to wear and tear, planet tooth and middle fluted disc self-centering, stable, speed ratio is wide, the efficient height, and, install very convenient owing to integrate dynamo-electric.

Four, description of drawings

Below in conjunction with drawings and Examples the new figure of this practicality is further specified.

Accompanying drawing is the structural representation of the utility model embodiment.

Among the figure; (1) axle sleeve; (2) oil sealing; (3) fore bearing; (4) output disk axle; (5) front end housing; (6) ball outer ring; (7) ball inner ring; (8) output planetary tooth; (9) gear ring is decided in output; (10) intermediate disc tooth axle; (11) gear ring is decided in input; (12) input gear; (13) support; (14) motor shaft; (15) motor stator; (16) rotor; (17) sealed terminal box; (18) stator retainer ring; (19) rear end cap; (20) rear bearing; (21) over cap; (22) safety disc

Five, embodiment

Among the figure, be fixed with three little axles that are mutually hexagonal angle and radially equate on the output disk axle (4), little axle is gone up each equipped output planetary tooth (8), and decides gear ring (9) engagement with output, and output is decided gear ring (9) and is packed on the support (3).Be fixed with on the intermediate disc tooth axle (10) and be mutually hexagonal angle and radially equal three little axles, this little axle is gone up each equipped line of input amount tooth, and decides gear ring (11) with input and mesh.Input is decided gear ring (11) and is packed on the support (13).Input gear (12) is packed on the motor shaft (14); motor shaft (14) front end installs bearing; install rotor (16); rear end cap (19) is packed on the support (13); safety disc (22) and over cap (21) are packed on the rear end cap (19); sealed terminal box (17) is packed on the support (13), fills with insulating oil in the motor.

When rotor turned clockwise, input gear (12) drove rotation to input planet tooth, because the effect of gear ring is decided in input, intermediate disc tooth axle (10) is done running clockwise again, in like manner, makes output disk axle (4) make clockwise low-speed running.

Claims (2)

1, oil immersed type decelerator is made up of from suspension type planetary reduction gear two large divisions oil immersed type sealed electric-motor and twin-stage; It is characterized in that: motor partly comprises common motor, but its support (13) and twin-stage are from suspension type planetary reduction gear consubstantiality, radiating ribs adds sealed terminal box (17), stator retainer ring (18), safety disc (22), protection end cap (21) again for radially being provided with and strengthening, and fills with insulating oil and forms; Deceleration part adopts twin-stage from suspension type planetary reduction gear principle, it comprises output disk axle (4), output is decided gear ring (9) and is packed on the support (13), intermediate disc tooth axle (10) and input are decided gear ring (11) and are packed on the support (13), the input gear is packed on the motor shaft (14), it decides gear ring (11) engagement by input planet tooth and input, and in like manner, intermediate disc axle (10) is decided gear ring (9) engagement through output planetary tooth (8) and output.
