Abstract

A mechanical overload protector changes the original sliding friction between the end surfaces of an output end and a stress end in an overload occasion into rolling friction, where in the output end refers to the overload protection end of the mechanical overload protector, and the stress end refers to the fixed end of the mechanical overload protector, the loss of the output end is enabled to be reduced when the output end runs in the overload occasion, the output end is effectively protected in the overload occasion, and the service life of the output end is prolonged. The mechanical overload protector is simple and compact in structure, can be arranged corresponding to the changes of the geometric dimensions of the output end and the stress end.

Description

Mechanical overload protector
Technical field
The present invention relates to mechanical overload protector.
Background technique
At present, generally adopt coupling in mechanical transmission, clutch, Coupler are realized the transmission of torsion, and by clutch, the overload of Coupler is skidded to automatically controlled part and transmitted the torque force overload signal, cut off the electricity supply, thereby realization is for the protection of torsion output terminal; This mode makes output terminal also want overload operation a period of time when overload, in the course of time also can be to the output terminal injury.Given this plant situation, we have developed this mechanical overload protector.
Summary of the invention
This patent invention relates to mechanical overload protector, during with in the past overload, output terminal (the overload protection end in the present invention) has changed rolling friction into the sliding friction of force side (fixed end in the present invention) end face, make output terminal (the overload protection end in the present invention) in the situation that the loss of transshipping when moving reduces, effectively protect output terminal (the overload protection end in the present invention) when overlond running, extended the working life of output terminal (the overload protection end in the present invention); And the present invention is simple in structure, compactness; Can be according to the corresponding mechanical overload protector of geometrical variations correspondence of output terminal (the overload protection end in the present invention), force side (fixed end in the present invention);
Utilize the position, hole on overload protection end circumference to substitute deep groove ball bearing retainer, steel ball in the position, hole carries out line with the groove of fixed end and contacts, make overload protection end and fixed end form the coaxial positioning of the contact form of rolling friction at circumferencial direction, the location of steel ball (3) is controlled by the interior hexagonal Cock screw (5) in this position, hole;
The contact form of steel ball (3) and groove is axially locating overload protection end and fixed end also;
Utilize position, hole on end face to substitute the retainer of thrust ball bearing, the sideline, aperture of the correspondence of the steel ball in the position, hole on close contact fixed end end face under the effect of Compress Spring (4), load during greater than the pretightening force of spring steel ball (3) be extruded aperture on end face, steel ball (3) and the rolling friction of end face formation stages.
Description of drawings
Fig. 1 is the mechanical overload protector assembly structure figure; In figure, 1 is the overload protective device fixed end, and 2 is overload protective device overload protection end, and 3 is steel ball, and 4 is Compress Spring, and 5 is interior hexagonal Cock screw, and 6 is hexagon socket cap head screw;
Fig. 2 is mechanical overload protector fixed end structural drawing;
Fig. 3 is mechanical overload protector overload protection end structure figure;

Embodiment
Position, hole on overload protection end circumference has substituted deep groove ball bearing retainer, steel ball in the position, hole carries out line with the groove of fixed end and contacts, make overload protection end and fixed end form the coaxial positioning of the contact form of rolling friction at circumferencial direction, the location of steel ball (3) is controlled by the interior hexagonal Cock screw (5) in this position, hole;
The contact form of steel ball (3) and groove is axially locating overload protection end and fixed end also;
Position, hole on overload protection end end face has substituted the retainer of thrust ball bearing, the sideline, aperture of the correspondence of the steel ball in the position, hole on close contact fixed end end face under the effect of Compress Spring (4), load during greater than the pretightening force of spring steel ball (3) be extruded aperture on end face, steel ball (3) and the rolling friction of end face formation stages;
During overload, steel ball is ejected the aperture, and axial due to the rolling friction form of protection end to overload protection end and fixed end radially located, and the end face of fixed end and overload protection end is also rolling friction; In such cases, even the electrical equipment overload protection is malfunctioning, can be to the output terminal injury yet.

Claims (5)

1. mechanical overload protector; when it is characterized in that overload, the sliding friction of output terminal and force side end face has changed rolling friction into; make output terminal in the situation that the loss of transshipping when moving reduces, effectively protected output terminal when overlond running, extended the working life of output terminal.
2. mechanical overload protector according to claim 1; it is characterized in that the position, hole on overload protection end circumference has substituted deep groove ball bearing retainer; steel ball in the position, hole carries out line with the groove of fixed end and contacts; make overload protection end and fixed end form the coaxial positioning of the contact form of rolling friction at circumferencial direction, the location of steel ball is controlled by the interior hexagonal Cock screw in this position, hole.
3. mechanical overload protector according to claim 1, the contact form that it is characterized in that steel ball and groove is axially locating overload protection end and fixed end also.
4. mechanical overload protector according to claim 1; it is characterized in that the position, hole on overload protection end end face has substituted the retainer of thrust ball bearing; the sideline, aperture of the correspondence of the steel ball in the position, hole on close contact fixed end end face under the effect of Compress Spring; load during greater than the pretightening force of spring steel ball be extruded aperture, steel ball and the rolling friction of end face formation stages on end face.
5. mechanical overload protector according to claim 1, is characterized in that when overload, the electrical equipment overload protection is malfunctioning, also can be to the output terminal injury.
