Abstract
A transmission connection mechanism comprises a nodular cast iron sleeve connected with a working machine spindle. The nodular cast iron sleeve is inlaid in an inner hole of an output hollow shaft of a speed reducer and is connected with the output hollow shaft of the speed reducer through a straddle screw, and a lock disc is arranged on the outer diameter of the output hollow shaft of the speed reducer. Nodular cast iron which is a different material is inlaid between the working machine spindle and the output hollow shaft of the speed reducer, so that bonding can be prevented even if impact loads and small relative sliding occur. Through the shear force produced by torsion is large, the nodular cast iron sleeve is inlaid in the speed reducer output hollow shaft which is high in toughness, the deformation is small, and fracturing cannot occur. During the maintenance of the working machine or the speed reducer, bonding is prevented, so that the working machine spindle and the speed reducer output hollow shaft can be separated easily by loosening the lock disc. The mechanism is convenient to dismount and capable of protecting the connection part safety well, saving maintenance time and improving the work efficiency.
Description
Technical field
The present invention relates to a kind of bindiny mechanism, particularly a kind of transmission connecting mechanism.
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.Good mechanical property, high-intensity forged material are generally used in this class application, 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 object of the present invention is to provide a kind of transmission connecting mechanism; at speed reducer output hollow shaft, be embedded in spheroidal graphite cast iron cover; the whole transmission connecting mechanism 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 present invention takes is:
A kind of transmission connecting mechanism, comprises the spheroidal graphite cast iron cover 3 being connected with working machine main shaft 1, and 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 is used junction of the edges of two sheets of paper screw 2 to be connected with hollow shaft 5.
Beneficial effect of the present invention:
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 when 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 invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
With reference to accompanying drawing, a kind of transmission connecting mechanism, 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 is used 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 is used junction of the edges of two sheets of paper screw 2 to be connected with hollow shaft 5.While preventing machining, spheroidal graphite cast iron cover 3 skids.
Working principle of the present invention 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 when 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.During 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.
