Abstract
The utility model provides a rotary flexible supporting and locating device of a shaft sleeve, belonging to the field of supporting and locating devices of shaft sleeves. The device comprises a bracket (3), a pin shaft (4), a rotary arm (5), a screw pin (6), a support seat (7) and a stand (8), wherein the bracket (3) is connected with the rotary arm (5) through the pin shaft (4), the other end of the rotary arm (5) is connected with the support seat (7) through the screw pin (6), the support seat (7) is fixed on the stand (8), a shaft (2) is arranged in the shaft sleeve (1), and the shaft sleeve (1) is fixed on the bracket (3). The device can limit the shaft sleeve from rotating along with the shaft and allow the shaft sleeve to move or wing along with the shaft to certain extent in radial direction, therefore, abrasion between the shaft and the shaft sleeve is lightened, and deadlocking of the shaft is prevented; the device is generally used for the cantilever shaft end and is usually used for a shaft with a smaller diameter. The device has the advantages of simple structure, low cost, easy installation and convenient maintenance.
Description
Technical field
The utility model relates to the supporting and positioning device of axle sleeve, especially relates to the flexible support positioning device of cantilevered axle axle sleeve.
Background technique
In mechanical transmission structure, good multiaxis is arranged, what these had self rotates, what have also is created in radial motion or swing, on these axles especially the end axle sleeve is installed, require axle sleeve not rotate in the design with the axle of inside, axle sleeve is fixed at axial position, do not allow axial motion, but allow axle sleeve to produce radial motion or swing with the axle of inside.Common structure is that axle sleeve directly is connected with frame, though the axial position of this structure energy fixed axle sleeve, axle sleeve can not produce radial motion or swing with axle, make axle and axle sleeve wearing and tearing aggravate, even the stuck axle that makes can't rotate; If between axle sleeve and the axle bearing or Sealing are arranged, will damage.When smaller and axle sleeve was installed in the end of axle when the diameter of axle, the situation of the stuck damage of wearing and tearing was more serious.
The model utility content
The purpose of this utility model is: overcome the prior art axle sleeve and can not produce the shortcoming of radial motion with axle, provide a kind of axle sleeve rotary flexible support positioning device.
Technological scheme is: this device comprises axle sleeve and supporting and positioning device, wherein said supporting and positioning device comprises parts such as support, bearing pin, pivoted arm, screw pin and supporting base, support is connected with pivoted arm by bearing pin, the other end of pivoted arm is connected with supporting base by screw pin, and supporting base is fixed on the frame; Axle is in axle sleeve, and axle sleeve is fixed on the support.
When axle rotates,, limited the rotation of axle sleeve because axle sleeve is connected with frame by supporting and positioning device; Because support, bearing pin, pivoted arm, screw pin and supporting base and frame are rigidly connected axial formation, have limited the axial motion of axle sleeve.
There is certain established angle in each parts of support, pivoted arm and supporting base that are connected with screw pin by bearing pin, between can rotate mutually, when axle has radial motion or when swing, above-mentioned supporting and positioning device can make axle sleeve along with axle generation radial motion or swing.
The beneficial effect of this device is: the restriction axle sleeve rotates with axle, allows axle sleeve with axle certain motion or swing being arranged radially, has therefore alleviated axle and axle sleeve wearing and tearing, prevents that axle is stuck; If between axle sleeve and the axle bearing or Sealing are arranged, can therefore not damage; This device generally is used for the cantilever axle head, and is usually used in the less axle of diameter.This apparatus structure is simple, and is with low cost, installs easily, easy to maintenance.
Description of drawings
The rotary flexible support positioning device of Fig. 1 axle sleeve sectional drawing;
The rotary flexible support positioning device of Fig. 2 axle sleeve outline drawing.
Mark among the figure:
1-axle sleeve 2--axle 3-support 4--bearing pin 5--pivoted arm
6--screw pin 7--supporting base 8--frame
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, this device comprises axle sleeve and supporting and positioning device, and wherein said supporting and positioning device comprises parts such as support 3, bearing pin 4, pivoted arm 5, screw pin 6, supporting base 7, and supporting base 7 is fixedly connected on the frame 8; Support 3 is connected with pivoted arm 5 by bearing pin 4, and the other end of pivoted arm 5 is connected with supporting base 7 by screw pin 6; Axle 2 is in axle sleeve 1, and axle sleeve 1 is fixedly connected on the support 3.The said fixing Placement can also can adopt welding, riveted joint with bolt or screw etc.
When axle 2 rotates, because axle sleeve 1 is connected with frame 8 by supporting and positioning device, limited the rotation of axle sleeve 1, also limited the axial motion of axle sleeve 1 simultaneously.
Can rotate mutually between support 3 that connects by bearing pin 4 and the pivoted arm 5, can rotate mutually between pivoted arm 5 that connects by screw pin 6 and the supporting base 7, above-mentioned each parts exist certain established angle to make supporting and positioning device to stretch and to compress.When axle 2 has radial motion or when swing, be installed in axle sleeve 1 on this supporting and positioning device along with radial motion or swings take place axle 2.
Claims (1)
1. rotary flexible support positioning device of axle sleeve, comprise axle sleeve and supporting and positioning device, it is characterized in that: described supporting and positioning device comprises support (3), bearing pin (4), pivoted arm (5), screw pin (6), supporting base (7), frame (8), its medium-height trestle (3) is connected with pivoted arm (5) by bearing pin (4), the other end of pivoted arm (5) is connected with supporting base (7) by screw pin (6), supporting base (7) is fixed on the frame (8), and axle sleeve (1) is fixed on the support (3).
