Abstract
The utility model discloses a screw adapting device for adapting a shaft with a shaft hub, the device applies to a flexible screw crossing a ring groove arranged between the shaft and the shaft hub adapting surface to form an adapting ring, thereby adapting the shaft and elements like the shaft hub together and realizing the axial location between the shaft and the shaft hub and the multiple rotary motion. The utility model has simple structure, easy processing, reliable coupling, the precision of axial location is higher than pin connection, and kinematics pair are not easily abraded.
Description
Technical field
The utility model relates to a kind of Bolt Connection device, relates in particular to a kind of Bolt Connection device that axle is connected with propeller boss class part.
Background technique
For coaxial mounted axle and propeller boss, produce axial displacement mutually in order to limit it, mostly traditional joining method is to adopt radially pin or key to connect.Although the pin connecting structure is simple, be easy to install, because pin only connects for the some contact, in the actual motion of relevant device, can make axle and propeller boss bumpy motion, kinematic accuracy is low, and kinematic pair also is easy to wear and tear, the reduction service life of equipment.
The model utility content
The utility model provides a kind of simple in structure, reliable Bolt Connection device that connects with propeller boss of connection.
For solving the problems of the technologies described above, the utility model has adopted following technological scheme: Bolt Connection device described in the utility model comprises screw bolt and nut, and described bolt is the flexible bolt with sufficient length; Be respectively equipped with the semi-circular groove that adapts with flexible bolt radius on the cylindrical circumferential surface of coupled axle and on the interior round side face of coupled propeller boss, flexible bolt is threaded in the formed annular chamber of this two semi-circular groove.
The utility model adopts flexible bolt to penetrate on axle and the joining circumferential surface of propeller boss in the formed circular groove, axle is linked together in the mode that circumferential surface contacts with propeller boss class part, make axle can do relative rotation motion with propeller boss, and realized the axially locating of axle and propeller boss simultaneously, its connection is more reliable, is applicable to that a lot of needs carry out axle and propeller boss connection and make the occasion of relative rotation motion.
When assembling, the rotatable nut that matches tangentially moves flexible bolt in coupled the formed annular chamber of two semi-circular groove, form a coupling ring, thereby axle and propeller boss are linked together.Generally, the length that flexible bolt penetrates in the annular chamber surpasses 1/4 of annular chamber girth, can realize more firm connection.In order to obtain more positive connection, the length that flexible bolt penetrates in the annular chamber should surpass 1/2 of annular chamber girth.
When remove connecting, as long as the counter-rotation nut, flexible bolt is tangentially withdrawed from two coupled two semi-circular groove get final product.
For reducing the resistance to motion that flexible bolt penetrates, as required, can on semi-circular groove or flexible bolt, annotate in advance during assembling lubricant oil or lubricating grease.
The utility model is simple in structure, and processing ease connects reliably, and the axially locating precision is higher than pin and connects, and kinematic pair is not easy to wear.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Embodiment
As shown in Figures 1 and 2, the utility model comprise flexible bolt 1,, nut 5 and supporting open washer 3 and Cock screw 4.On the inner peripheral surface of coupled axle 2 outer peripheral surface of need and propeller boss 6, be respectively equipped with semicircle annular groove, and corresponding the merging forms annular chamber 9.The diameter of the diameter of annular chamber 9 and flexible bolt 1 and and the diameter of coupled axle 2 adapt, the length of flexible bolt 1 adapts with the girth of annular chamber approximately.
Simultaneously, the semi-circular groove of propeller boss 6 tangentially be provided with circular hole and nut seat hole with the semi-circular groove equal diameters, nut 5 is fixing by opening pad 3 and Cock screw 4 in the nut seat hole, makes nut can only do rotation motion, can not move axially.
During assembling, rotating nut 5 tangentially moves flexible bolt 1 in the annular chamber between coupled 9, until a circle, thereby form a coupling ring, realizes the axial connection and relative rotation motion of axle 2 and propeller boss 6.When remove connecting, as long as counter-rotation nut 5, flexible bolt 1 is tangentially withdrawed from the annular chamber 9 between two coupled get final product.
Claims (4)
1, a kind of Bolt Connection device that connects with propeller boss comprises screw bolt and nut, and it is characterized in that: described bolt is the flexible bolt with sufficient length; Be respectively equipped with the semi-circular groove that adapts with flexible bolt radius on the cylindrical circumferential surface of the axle that is needed to connect and on the interior round side face of coupled propeller boss, described flexible bolt is threaded in the annular chamber of this two formation that semi-circular groove merges.
2, Bolt Connection device as claimed in claim 1 is characterized in that: described flexible bolt penetrates length greater than 1/4 of annular chamber girth in described annular chamber, the longest suitable with the annular chamber girth.
3, Bolt Connection device as claimed in claim 1, it is characterized in that: the pitch of described flexible bolt is slightly larger than the pitch with the diameter standard bolt.
4, as claim 1,2 or 3 described Bolt Connection devices, it is characterized in that: described nut is fixed by opening pad and Cock screw.
