Description

The method of ring and outer shroud surface of contact size in a kind of definite locking plate
Technical field:
The invention belongs to mechanical connection spare design field, be specifically related to the method for the interior ring of a kind of definite locking plate and outer shroud surface of contact size.
Technical background:
Locking plate, full locking connection dish by name comprises that push bolt 1, interior ring 2, outer shroud 3, axle sleeve 4(are as shown in Figure 1), be pressure and the frictional force transmitted load of utilizing Desing of Interference Joint to produce, last century, early eighties just was used widely in developed country.Locking plate belongs to the keyless joint device, is adapted at using under the fully loaded transportation condition, and its characteristics are: manufacturing process is simple, and installation and removal are convenient, long service life, and as the overload phenomenon occurs, mechanism can lose the connection effect, has effectively protected transmission device, and is safe and reliable.Now, locking plate is fully used in a plurality of fields, such as wind power plant, large-scale transmission equipment, nuclear facility etc.The base dimension of locking plate comprises the diameter of transmission shaft 5 , locking diameter (ring 2 and the diameter of axle sleeve 4 surface of contact namely)
Figure 547924DEST_PATH_IMAGE002
, diameter of centre hole in bolts , interior ring and the axial length L of axle sleeve surface of contact and the minimum diameter of outer shroud 3 , base dimension can be found from series of tables.But design method and the prematurity and perfect of ring and outer shroud surface of contact size in determining.To be the formula of utilizing magnitude of interference to the size of locking plate and calculating parameter debugged the method for ring and outer shroud surface of contact size repeatedly draws in tradition was determined, but interrelated between calculating parameter, computational process is complicated, and amount of calculation is large, and the size of design also needs through repeatedly checking and comparing.And with the difference of required torque, even under with a series of base dimensions, the surface of contact size of interior ring and outer shroud also will change, and has prolonged like this construction cycle of product without the design method of clear and definite size relationship.
Summary of the invention:
The purpose of this invention is to provide the method for encircling in a kind of definite locking plate with outer shroud surface of contact size.It can determine the diameter at each key point place of interior ring outer surface quickly and easily

Because of the restriction of difference and the machining accuracy of requirement moment of torsion, with a series of locking plate, interior ring is not identical with the final size of outer shroud design yet.But the size of using said method to draw can be used as the Source size of determining final size, by Source size each surface of contact is carried out the calculating of magnitude of interference, according to result of calculation and designing requirement, revises Source size and obtains shaping size.Said method can guarantee that only needing that its parameter is done small change can obtain comparatively desirable design size, reaches designing requirement.
Advantage of the present invention and good effect:
Use this method can determine quickly and easily the size of interior ring and each key point of outer shroud surface of contact, avoid the repeatedly debugging to size, simplified the design process of locking plate.Through theoretical validation, the size conforms magnitude of interference requirement that the method is determined.
