Abstract
The present invention disclose a kind of on small axle diameter motor shaft trim fix the method for pendulum, comprising: one semi-circular recesses is set in one end of pendulum, the diameter of described semi-circular recesses, equal the diameter of small axle diameter motor shaft; There is provided a balancing weight, this balancing weight arranges a groove identical with pendulum upper semi-circle connected in star, and after pendulum and balancing weight are combined, two grooves can form the axis hole of the equal diameters of a diameter and small axle diameter motor shaft relatively; The weight of adjustment balancing weight and pendulum, the barycenter after pendulum and balancing weight are combined is positioned at the axle center place of axis hole; Small axle diameter motor shaft is placed in the axis hole after balancing weight and pendulum combination, and by screw, balancing weight and pendulum is fixed, motor shaft is fixed in axis hole.
Description
Technical field
The present invention relates to a kind of method of trim retaining element on small axle diameter, particularly a kind of in infrared imaging system on small axle diameter motor shaft trim fix the method for pendulum.
Background technology
In infrared imaging mechanism, use a kind of pendulum, drive its rotary work by direct current machine.As shown in Figure 1 and Figure 2, described pendulum 1 is provided with axis hole 2 ', and the output shaft 4 of direct current machine 3 is fixed in axis hole 2 ', relies on direct current machine rotating band movable pendulum sheet 1 to rotate.This mode is applicable to the situation that motor output shaft is more than or equal to φ 3mm, because when motor output shaft is more than or equal to φ 3mm, a facet 5 can be established on axle, utilize this facet as installation stationary plane, by the screw of dog screw 6 and axis hole side, pendulum handle and motor output shaft can be fixed.But when motor output shaft is less than φ 3mm, be just difficult to arrange such plane.Motor shaft and pendulum handle cannot be fixed by set screw in such cases, pendulum handle and motor shaft can only be sticked together with glue, this practice is both unreliable, is not easy to again dismounting and changes pendulum.
Summary of the invention
The object of the present invention is to provide the structure of pendulum used in infrared imaging mechanism, solve fixing on small axle diameter motor and trim pendulum.
Technical scheme of the present invention is as follows:
On small axle diameter motor shaft, a method for pendulum is fixed in trim, it is characterized in that:
(1) one semi-circular recesses is set in one end of pendulum, the diameter of described semi-circular recesses, equals the diameter of small axle diameter motor shaft;
(2) provide a balancing weight, this balancing weight arranges a groove identical with pendulum upper semi-circle connected in star, and after pendulum and balancing weight are combined, two grooves can form the axis hole of the equal diameters of a diameter and small axle diameter motor shaft relatively;
(3) adjust the weight of balancing weight and pendulum, the barycenter after pendulum and balancing weight are combined is positioned at the axle center place of axis hole;
(4) small axle diameter motor shaft is placed in the axis hole after balancing weight and pendulum combination, and by screw, balancing weight and pendulum is fixed, motor shaft is fixed in axis hole.
In said method, pendulum and balancing weight can adopt the material of different densities to make respectively, and the density of balancing weight is greater than the density of pendulum.
The present invention, by by arranging a balancing weight, balancing weight and pendulum arranges semi-circular recesses that a diameter equals motor shaft diameter respectively, and like this after balancing weight and pendulum are connected, motor shaft can tightly be fixed by the axis hole that two semicircular connected in star is formed.The diameter of method no matter motor shaft is all applicable, is particularly useful for small axle diameter motor, solves the problem being difficult to when motor shaft is too small at present fix with pendulum handle.The present invention, also by adjusting the weight of balancing weight and pendulum, making the barycenter after balancing weight and pendulum combination be positioned at motor shaft place, thus making pendulum can be parked in any position around motor output shaft.

Embodiment
The method of pendulum is fixed in the present invention's trim on small axle diameter motor shaft, comprises the following steps:
(1) arrange a semi-circular recesses 11 in one end of pendulum 1, the diameter of described semi-circular recesses 11, equals the diameter of small axle diameter motor shaft.The pendulum structure of semi-circular recesses is set as shown in Figure 3.
(2) balancing weight 7 is provided, this balancing weight arranges a groove 71 identical with pendulum upper semi-circle connected in star, as shown in Figure 4;
After pendulum and balancing weight are combined, two groove 11 axis holes 2 of forming the equal diameters of a diameter and small axle diameter motor shaft relative to 71, as shown in Figure 5.
(3) adjust the weight of balancing weight and pendulum, the barycenter after pendulum and balancing weight are combined is positioned at the axle center place of axis hole 2;
(4) motor shaft of small axle diameter motor 3 is placed in the axis hole 2 after balancing weight and pendulum combination, and by connecting screw 8, balancing weight and pendulum is fixed, make motor shaft be fixed in axis hole 2, as shown in Figure 6.
In said method, pendulum and balancing weight can adopt the material of different densities to make respectively, and the density of balancing weight is greater than the density of pendulum.The volume of balancing weight can be reduced like this.By calculating the volume of both adjustment, after balancing weight and pendulum just can be made to combine, the barycenter of assembly is positioned at motor shaft place, thus makes pendulum can be parked in any position around motor output shaft.
Claims (2)
1. on small axle diameter motor shaft, a method for pendulum is fixed in trim, it is characterized in that:
(1) one semi-circular recesses is set in one end of pendulum, the diameter of described semi-circular recesses, equals the diameter of small axle diameter motor shaft;
(2) provide a balancing weight, this balancing weight arranges a groove identical with pendulum upper semi-circle connected in star, and after pendulum and balancing weight are combined, two grooves can form the axis hole of the equal diameters of a diameter and small axle diameter motor shaft relatively;
(3) adjust the weight of balancing weight and pendulum, the barycenter after pendulum and balancing weight are combined is positioned at the axle center place of axis hole;
(4) small axle diameter motor shaft is placed in the axis hole after balancing weight and pendulum combination, and by screw, balancing weight and pendulum is fixed, motor shaft is fixed in axis hole.
2. according to claim 1 a kind of on small axle diameter motor shaft trim fix the method for pendulum, it is characterized in that: pendulum and balancing weight adopt the material of different densities to make respectively, and the density of balancing weight is greater than the density of pendulum.
