Abstract

It the utility model is related to a kind of radial positioning latch structure applied to rotary part flange conjunction.The radial positioning latch structure is the radial positioning latch structure designed based on the situation that can not process axially position pin-and-hole.The structure is applied to using seam cooperation, the positioning of two rotary parts connected with flange.The structure forms the hexagon socket head cap screw in the face of conjunction flange is bonded to by the composition surface of conjunction is positioned radially in two flanges alignment pin and by alignment pin.The structure has taken into full account influence of the centrifugal force to alignment pin as caused by rotation, simple in construction, easy to process, reliability is high.

Description

Radial positioning latch structure applied to rotary part flange conjunction

Technical field：It the utility model is related to a kind of radial positioning latch structure applied to rotary part flange conjunction.

Background technology：As shown in figure 4, when the flange of two rotary parts to being coordinated using seam is carried out closing, work Commonly used locating pin structure is axial positioning structure in journey.As shown in figure 5, when carrying out fraising to pin-and-hole, it is necessary to adjust Conjunction is fixed after good position the flange of two rotary parts, then carry out twisting with brill vertically.Ordinary circumstance, this location structure exist It is easily achieved in processing technology.But occasionally there are it is following the fact that：After the flange handle of two rotary parts closes, its Surrounding structure part is interfered with machining tool, and no sufficient space carries out fraising operation as shown in fig. 6, such as needing to process in this case Axial pin-and-hole, then need by increasing axial length, increasing flange diameter to solve the space problem of process operation, as shown in Figure 7. And axial length increase can increase shafting amount of deflection or deformation, so as to increase the unstability of shafting vibration and rotary part, turn The high situation of speed is also possible to cause to damage；Rotary part weight can also be increased by increasing flange diameter, bring extra swing.Especially Rotor structure is so hung for elevator motor, shafting lengthening, weight increase can all cause bad to the stable operation of motor Influence.Radial positioning latch structure provided by the utility model, it is in two flange joint radial direction pin hole processings, such as Fig. 8 institutes Show, it is easy to operate, do not limited by structure space, can greatly shorten the axial design length of rotary part, be advantageous to whole The stabilization of shafting, it is especially suitable for requiring high occasion to axial length.

The content of the invention：The purpose of this utility model is in the case where axially position pin-and-hole can not be processed, there is provided is applied to Radial positioning latch structure of the rotary part flange conjunction.The technical solution of the utility model is：One kind is applied to rotary part method The blue radial positioning latch structure conjunction, active rotation part (1) carry flange, active rotation portion with driven rotary part (2) Part (1) is coordinated with driven rotary part (2) using flange seam, and conjunction structure (3) (is carried out handle with what nuts and bolt formed Close, both active rotation part (1) and driven rotary part (2) are carrying radial positioning pin (4), soket head cap screw between conjunction face (5) radial positioning pin (4) is put together on the flange of rotary part (2).

Operation principle of the present utility model：Radial positioning pin is arranged on the one of flange of agent structure with soket head cap screw On, then processed in advance with another flange with alignment pin coincide concave surface position engage, after flange formation one restrict The location structure of two circumference of flange direction displacements.While being intended to the seam mating connection control radial displacement by two flanges, Solves the displacement problem of circumferencial direction.

Technique effect of the present utility model：The utility model, which is applied to two, to be needed by flange the rotation being integrated The positioning of part, solves flange orientation problem when can not process axially position pin.The structure has taken into full account radial positioning Sell fixation and stop on rotary part.The structure plays a part of positioning and transmitting moment of torsion.Structure energy of the present utility model Conjunction face joint is radially arranged alignment pin in two flanges and positioned by enough completions, while meets the fixation that rotary part uses And intensity requirement.

Embodiment：

As shown in figure 1, it is a kind of applied to rotary part flange the radial positioning latch structure of conjunction, active rotation part 1 with Driven rotary part 2 carries flange, and active rotation part 1 is coordinated with driven rotary part 2 using flange seam, with nut and Bolt composition carries out conjunction structure 3 conjunction, and both active rotation part 1 and driven rotary part 2 are carrying footpath between conjunction face To alignment pin 4, soket head cap screw 5 puts together on radial positioning pin 4 on the flange of rotary part 2.

As shown in figure 1, first in two flange joint outer surfaces of active rotation part 1 and driven rotary part 2 along footpath To direction pin-and-hole is twisted with brill；Then two rotary parts are taken apart, wherein the flange of a rotary part being processed on conjunction face Joint hole needed for radial positioning pin is installed, its position of center line must be consistent with the center line for the pin-and-hole that preamble is processed；Such as figure 2nd, shown in Fig. 3, with soket head cap screw 5 conjunction fixed radial alignment pin 4；Conjunction there will be the flange of the alignment pin, with another rotation The dowel hole groove of part flange is coordinated, and the seam of two rotary part flanges is collectively forming to the two circumferencial direction With the positioning of radial direction.

Claims (1)

1. a kind of radial positioning latch structure applied to rotary part flange conjunction, it is characterized in that：Active rotation part (1) with from Dynamic rotary part (2) carries flange, and active rotation part (1) is coordinated with driven rotary part (2) using flange seam, uses spiral shell It is female conjunction structure (3) to be carried out conjunction, the two conjunction face of active rotation part (1) and driven rotary part (2) with what bolt formed Between carry radial positioning pin (4), soket head cap screw (5) puts together on radial positioning pin (4) on the flange of rotary part (2).
