Description
Technical field
The utility model relates to a kind of bindiny mechanism, particularly a kind of transmission connecting mechanism being used in conjunction with speed reducer.
Background technique
In some specific device, the output shaft of speed reducer drive parts is hollow shaft, and this hollow shaft is set on working machine main shaft, by locking plate, speed reducer hollow shaft and working machine principal shaft locking is carried out to transmitting torque.This class application is generally used good mechanical property, high-intensity forged material, and therefore the mechanical property similarity of material is very high.During due to work, impacted, relative slippage is occurred, therefore between speed reducer output hollow shaft and working machine main shaft, easily bondd, cause dismounting inconvenient, cannot be dismantled even.In order to change this situation, speed reducer output hollow shaft is adopted to cast iron materials, although can there is not bonding phenomenon, cast iron materials fragility is large, under impulsive load, often there is shear failure phenomenon in speed reducer output shaft.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model has been to provide a kind of transmission connecting mechanism being used in conjunction with speed reducer, be embedded in spheroidal graphite cast iron cover at speed reducer output hollow shaft, the whole a kind of transmission connecting mechanism being used in conjunction with to speed reducer forming can change the bonding of similar mechanical property material, can avoid again high pulling torque to impact under operating mode, the shear failure of spheroidal graphite cast iron cover, convenient disassembly
Well protect the safety of transmission device, saved the repair time, improved manufacturing efficiency.
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of transmission connecting mechanism being used in conjunction with speed reducer, comprise the spheroidal graphite cast iron cover 3 being connected with working machine main shaft 1, spheroidal graphite cast iron cover 3 is embedded in output hollow shaft 5 endoporus of speed reducer 6 and transition fit assembling, on the external diameter of the output hollow shaft 5 of speed reducer 6, locking plate 4 is installed.
Described spheroidal graphite cast iron cover 3 is greater than spheroidal graphite cast iron cover 3 and working machine main shaft 1 connection diameter with output hollow shaft 5 connection diameters of speed reducer 6.
Described spheroidal graphite cast iron cover 3 adopts Q600-3 or Q700-2 cast inblock.
Described spheroidal graphite cast iron cover 3 uses junction of the edges of two sheets of paper screw 2 to be connected with hollow shaft 5.
The beneficial effects of the utility model:
First spheroidal graphite cast iron cover 3 adopts the assembling of H7/m6 transition fit with the output hollow shaft 5 of speed reducer 6, then must use junction of the edges of two sheets of paper screw 2 to connect, because if after having assembled, there is gap, so in the time of processing spheroidal graphite cast iron cover endoporus, junction of the edges of two sheets of paper screw 2 connects the moment of torsion that the moment of torsion that produces produces when overcoming tool sharpening, prevents that spheroidal graphite cast iron cover 3 from skidding adding man-hour.After part machines, working machine main shaft 1 overlaps 3 endoporus with spheroidal graphite cast iron, and locking plate 4 is gapped with speed reducer 6 output hollow shaft 5 external diameters, can realize light assembling.After having assembled, locking plate 4, according to usage requirement locking, because spheroidal graphite cast iron cover 3 and output hollow shaft 5 connection diameters of speed reducer 6 are greater than spheroidal graphite cast iron cover 3 and working machine main shaft 1 connection diameter, therefore can meet the requirement of transmitting torque.
Accompanying drawing explanation
Accompanying drawing is installation diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to accompanying drawing, a kind of transmission connecting mechanism being used in conjunction with speed reducer, comprise the spheroidal graphite cast iron cover 3 being connected with working machine main shaft 1, spheroidal graphite cast iron cover 3 is embedded in output hollow shaft 5 endoporus of speed reducer 6 and transition fit assembling, spheroidal graphite cast iron cover 3 uses junction of the edges of two sheets of paper screw 2 to be connected with the output hollow shaft 5 of speed reducer 6, on the external diameter of the output hollow shaft 5 of speed reducer 6, locking plate 4 is installed.
Described spheroidal graphite cast iron cover 3 is greater than spheroidal graphite cast iron cover 3 and working machine main shaft 1 connection diameter with output hollow shaft 5 connection diameters of speed reducer 6.
Described spheroidal graphite cast iron cover 3 adopts Q600-3 or Q700-2 cast inblock.Forged material different in kind with working machine main shaft 1 and speed reducer 6 output hollow shafts 5.
Described spheroidal graphite cast iron cover 3 uses junction of the edges of two sheets of paper screw 2 to be connected with hollow shaft 5, and while preventing machining, spheroidal graphite cast iron cover 3 skids.
Working principle of the present utility model is:
After locking plate 4 is locked as requested, be interference and connect between each part, interference connects generation radial stress, and the moment of torsion that utilizes interference to connect generation transmits Operating torque.Because spheroidal graphite cast iron cover 3 and output hollow shaft 5 connection diameters of speed reducer 6 are greater than spheroidal graphite cast iron cover 3 and working machine main shaft 1 connection diameter, therefore in can meeting the requirement of transmission Operating torque, can there is not relative sliding with the output hollow shaft 5 of speed reducer 6 in spheroidal graphite cast iron cover 3.Owing to there being the spheroidal graphite cast iron of unlike material to be embedded between working machine main shaft 1 and the output hollow shaft 5 of speed reducer 6, even if therefore there is impulsive load to occur, and make it that little relative sliding occur again, also can not cause bonding phenomenon.When work, moment of torsion can overlap to spheroidal graphite cast iron the shear deformation of 3 generations, but because it is embedded in the output hollow shaft 5 of the speed reducer 3 that toughness is higher, therefore distortion is less, there will not be phenomenon of rupture.
In accompanying drawing: 1 is working machine main shaft; 2 is junction of the edges of two sheets of paper screw; 3 is spheroidal graphite cast iron cover; 4 is locking plate; 5 is output hollow shaft; 6 is speed reducer.
