Description

A kind of support of centrifuge pivoted arm and drive mechanism
Technical field
The invention belongs to centrifuge technique fields, and in particular to a kind of support of centrifuge pivoted arm and drive mechanism.
Background technique
Centrifuge is widely used in civil engineering, aerospace, detection calibration etc. as test platform.According to effect Difference, there is some difference for centrifuge specific structure, but principle is almost the same, and structure composition is also roughly the same.In main structure Power source, transmission main shaft and pivoted arm are essential, the support of transmission main shaft and its with the connection of pivoted arm then shape as the case may be Formula is different.
The typical centrifuge transmission main shaft support kind of drive mainly has following two schemes:
1, scheme 1 as shown in Figure 4, Figure 5, shows motor 1 in figure;Motor shaft 11;Motor mounting surface 12;Rigid connector 10, motor shaft (reducer output shaft) is transmission main shaft, and pivoted arm is directly installed on motor shaft by rigid connection member.
2, scheme 2 as shown in Figure 6, Figure 7, shows motor 1 in figure;Motor shaft 11;Motor mounting surface 12;Pivoted arm 2;Support Seat 3;Supporting seat mounting surface 31;Bearing 4;Shaft coupling 8;Connecting shaft 9;Rigid connector 10, motor shaft (reducer output shaft) with Transmission main shaft is connected by shaft coupling, and transmission main shaft is equipped with dedicated support system.Pivoted arm is installed in biography by rigid connection member On dynamic main shaft.
Two schemes are wider in existing centrifuge field application, and technology is more mature.But it is directed to different equipment requirements, It has some disadvantages.
1,1 pivoted arm of scheme is directly installed on motor shaft, and support stiffness is small, and motor can be generated during driving and be diminished not The electric and magnetic oscillation fallen, directly affects pivoted arm.
2, the major defect of scheme 2 is that installation dimension is big, and structure is not compact enough, need to design multilayer mounting surface, mounting and adjusting Difficulty is relatively large.
We has developed a kind of support of centrifuge pivoted arm and drive mechanism in order to solve problem above.
Summary of the invention
The object of the invention is that providing a kind of support of centrifuge pivoted arm and drive mechanism to solve the above-mentioned problems.
The present invention through the following technical solutions to achieve the above objectives:
A kind of support of centrifuge pivoted arm and drive mechanism are provided with perpendicular for the connection between motor and pivoted arm on pivoted arm To through-hole;Support and drive mechanism include:
Support base;Support base is infundibulate, and support base reversely covers at the top of motor;Circular ring shape is formed on the bottom of support base Supporting seat mounting surface, the side wall of motor are formed as the circular ring shape motor mounting surface being unfolded around;Supporting seat mounting surface and motor Mounting surface is parallel or is generally aligned in the same plane, and supporting seat mounting surface and motor mounting surface are fixedly mounted on same pedestal;
Bearing group;Be formed as annulus column bracing structure at the top of support base, bearing group is fixedly set in lateral branch On support structure, the outer ring of bearing group and the through-hole wall of pivoted arm are connected;
Excessive part;
Connector;
Adapter;Motor shaft is penetrated from bracing structure interior bottom portion, and is pierced by from the upper end;The top of motor shaft with Transition piece rigid connection;Adapter and pivoted arm are rigidly connected;Torque connection is transmitted by connector between transition piece and adapter.
The beneficial effects of the present invention are:
A kind of centrifuge pivoted arm support of the invention and drive mechanism;
1, since pivoted arm is supported directly on support base, support stiffness is compared directly to be packed on motor shaft and be obtained very greatly It is promoted;
2, in addition, Motor torque is transmitted to pivoted arm by connector, connector is reasonably devised, so that the torsion of connector It is relatively high to turn rigidity, motor oscillating can be well isolated, avoid passing to pivoted arm;
3, support base and motor upper cover use sleeve structure, keep whole system compact-sized;Meanwhile motor mounting surface with Supporting seat mounting surface is closer to, and is parallel to each other therebetween or is generally aligned in the same plane, and same installation pedestal is arranged, and is added by machinery Work guarantees the two installation requirement, makes the reduction of total mounting and adjusting work difficulty, and ensure that support base is preferable with motor shaft Concentricity.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
Embodiment 1, as shown in Fig. 5, Fig. 6, Fig. 7;
A kind of support of centrifuge pivoted arm 2 and drive mechanism are arranged on pivoted arm 2 for the connection between motor 1 and pivoted arm 2 There is vertical through-hole;Support and drive mechanism include:
