Abstract
The utility model discloses a novel locking plate. The locking plate comprises an outer ring and an inner ring; the outer ring and the inner ring are assembled in a matched manner through a stepped conical surface; connection holes are formed both on the stepped surface in the outer ring and on the flange of the inner ring; the connection holes on the flange of the inner ring are smooth through holes; the connection holes on the stepped surface in the outer ring are through holes of which the surfaces are smooth; an end ring is arranged on the outer ring at the end far from the flange of the inner ring; and screw holes, of which the amount is the same as that of connection holes on the outer ring, are formed on the end ring. The utility model can reduce stress concentrated peak value of the outer ring, and improve the safety and the reliability of the locking plate.
Description
Technical field
The utility model relates to mechanical keyless joint shaft drive technical field, especially a kind of novel locking plate.
Background technique
Usually locking plate is made up of outer shroud, interior ring and bolt, outer shroud endoporus and interior ring cylindrical are made the step conical surface, outer shroud and interior ring are by the identical matched together of the step conical surface, the step place is shaped on a plurality of screw blind holes along circumference in the outer shroud, the opposite position place of interior ring also is shaped on the smooth through hole of equal amount, interior ring and outer shroud couple together by bolt, after promptly bolt penetrates from the smooth through hole on the interior ring flange, are screwed in the tapped blind hole of outer shroud.Locking plate installs to the transmission connection piece that is locked---on axle and the axle sleeve, ring forms the wedging relation in the locking plate between axle sleeve and outer shroud, after tighting a bolt one by one by the moment of setting, in axle sleeve, produce positive pressure between the cylindrical of circle and axle, because the existence of positive pressure makes axle and axle sleeve rely on stiction to come transmitting torque when transferring power.According to calculating and verification experimental verification, the screw blind hole at step place is a stress concentration point in the outer shroud, and there are a plurality of wedge angles vertically in screw blind hole itself, makes problem of stress concentration more outstanding, and too high stress is concentrated and made outer shroud have the risk that cracking takes place.
The model utility content
The purpose of this utility model provides a kind of novel locking plate, can reduce the peak value that outer shroud stress is concentrated, and improves the reliability of locking plate.
The technical solution of the utility model is: a kind of novel locking plate, comprise by the outer shroud and the interior ring of the identical matched together of the step conical surface, and in outer shroud, be equipped with attachment hole on step surface place and the interior ring flange.
Attachment hole on the interior ring flange is smooth through hole, and the attachment hole at step surface place is ganoid through hole in the described outer shroud.
The end away from interior ring flange at outer shroud is provided with end ring, corresponding being provided with and the identical screw hole of outer shroud attachment hole quantity on the end ring.
The another kind of technological scheme that the utility model adopted is: a kind of novel locking plate, comprise outer shroud and interior ring by the identical matched together of the step conical surface, in outer shroud, be equipped with attachment hole on step surface place and the interior ring flange, attachment hole in described on the ring flange is a tapped hole, and the attachment hole at step surface place is ganoid through hole in the described outer shroud.
The screw blind hole that the utility model will have step place in the locking plate outer shroud now changes smooth through hole into, and during use, each connecting bolt penetrates from interior ring flange one end, passes from outer shroud, uses nut check then one by one, can realize the function of locking plate.The utility model is made as tapped hole with the attachment hole on the interior ring flange, after simultaneously the attachment hole at step surface place in the outer shroud being made as ganoid through hole, in use, each connecting bolt penetrates from outer shroud one end, be screwed in the tapped hole corresponding on the interior ring flange, thus the locking function of realization locking plate.The utility model has been eliminated in the prior art because of outer shroud screw blind hole wedge angle and consequent peak stress, and the stress that greatly reduces outer shroud is concentrated, and has improved the Security and the reliability of locking plate.
The utility model is after end face one side of outer shroud is set up end ring, be shaped on the end ring and the identical screw hole of outer shroud attachment hole quantity, like this, each connecting bolt can directly screw in the screw hole corresponding on the end ring after passing interior ring, outer shroud, by bolt interior ring, outer shroud and end ring are linked into an integrated entity, realize the locking function of locking plate.Adopt end ring structure, stressed more even with respect to the locking mechanism of single nut, assemble easier.

Embodiment
As shown in fig. 1, the utility model mainly is made up of outer shroud 1, interior ring 2, end ring 3 and bolt 4, outer shroud and interior ring are by the identical matched together of the step conical surface, the attachment hole at step place all is set to ganoid through hole in the outer shroud 1, the opposite position place of interior ring 2 also is shaped on the smooth through hole of equal amount, the end away from interior ring flange at outer shroud 1 is provided with end ring 3, corresponding being provided with and the identical screw hole of outer shroud attachment hole quantity on the end ring 3.The smooth through hole that is passed interior ring 2 and outer shroud 1 by bolt 4 screws in the screw hole of end ring 3, and interior ring 2, outer shroud 1 and end ring 3 are linked together.As shown in Figure 3, during use, the utility model is installed to the transmission connection piece that is locked---on axle 6 and the axle sleeve 5, tight a bolt one by one, can realize the locking function of locking plate according to the Bolt Tightening Force square of setting.Fig. 1 installs to the state after the locking on axle 6 and the axle sleeve 5 for the preceding state of locking plate locking, Fig. 3 for locking plate.
When implementing, the also available nut of the end ring 3 that outer shroud 1 end face one side is provided with replaces, and promptly directly is connected with the bolt pairing with nut, can play locking function equally.
In addition, the end ring 3 of outer shroud 1 end face one side setting can not wanted yet among Fig. 1, at this moment, only needing the smooth through hole of the correspondence that will be provided with on interior ring 2 flanges to change tapped hole into gets final product, during use, the smooth through hole of bolt 4 from outer shroud 1 inserted and screw in the tapped hole of interior ring 2, can realize that locking connects, and specifically sees shown in Figure 2.
