Above-mentioned baffle plate is two symmetrically arranged Semicircular baffles.
Two Semicircular baffles are arranged symmetrically with along the center line of opening 6.
The internal diameter of above-mentioned adjustment pad is greater than the minimum diameter of tapered sleeve.
The thickness of above-mentioned adjustment pad is 0.2mm, 0.5mm or 1mm.
The width of above-mentioned opening is 2-4mm.
The internal diameter of above-mentioned baffle plate equates with the internal diameter of circular groove.
On one end end face that in above-mentioned tapered sleeve, internal diameter is little, be provided with bolt hole.
On above-mentioned baffle plate, be provided with bolt hole.
The beneficial effect of this programme can learn according to the narration to such scheme, and in this combined bearing pin, the tapering of its tapered sleeve and the axis of cone equates, the axis of cone and tapered sleeve can fully be fitted when mounted, to ensure the axial compression effect of the axis of cone to tapered sleeve.On the sidewall of described tapered sleeve, axially run through and be provided with strip gab along it, when this opening can ensure to install, tapered sleeve can slightly open under the axial compression effect of the axis of cone, so that tapered sleeve external diameter reaches usage requirement.The small end of the described axis of cone stretches out tapered sleeve, and in this section of stretching out, be provided with circular groove, baffle plate is installed in circular groove, between described baffle plate and the end face of tapered sleeve, adjustment pad is installed, described baffle plate and adjustment pad are connected and fixed by bolt assembly and tapered sleeve, and easy accessibility, adjusts by increasing or reduce the quantity of pad the axial position that the axis of cone packs tapered sleeve into, the slight external diameter tolerance of adjusting tapered sleeve, makes the external diameter of tapered sleeve reach the external diameter tolerance range of installation requirement.This combined bearing pin has wide range of applications, and be convenient to installation and removal, and the external diameter of tapered sleeve is adjustable, has ensured installation and removal quality.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of combined bearing pin, as shown in the figure, it comprises tapered sleeve 1 and is arranged on the axis of cone 5 in tapered sleeve 1, the tapering of described tapered sleeve 1 and the axis of cone 5 equates, after installing, tapered sleeve 1 is the conical surface with the surface of contact of the axis of cone 5, on the sidewall of described tapered sleeve 1, axially runs through and is provided with strip gab 6 along it, and the width of opening 6 is 2-4mm.The small end (being one end that diameter is little) of the described axis of cone 5 stretches out tapered sleeve 1, and in this section of stretching out, be provided with circular groove 7, baffle plate 4 is installed in circular groove 7, the internal diameter of baffle plate 4 equates with the internal diameter of circular groove 7, this baffle plate 4 is two symmetrically arranged Semicircular baffles, and two Semicircular baffles 4 are arranged symmetrically with along the center line of opening 6.Between described baffle plate 4 and the end face of tapered sleeve 1, be provided with and adjust pad 2, the internal diameter of adjusting pad 2 is slightly larger than the minimum diameter of tapered sleeve 1, the thickness of adjusting pad 2 is 0.2mm, 0.5mm or 1mm, also can according to requirements, the adjustment pad 2 of above-mentioned specification be used in combination.Described baffle plate 4 and adjustment pad 2 are connected and fixed by bolt assembly 3 and tapered sleeve 1, on one end end face that in tapered sleeve 1, internal diameter is little, be provided with bolt hole 8, on baffle plate 4, be provided with bolt hole 8, by coordinating of bolt assembly 3 and bolt hole 8, realize baffle plate 4 and adjust being connected and fixed of pad 2 and tapered sleeve 1.
The external diameter of tapered sleeve 1 is slightly less than the pin-and-hole internal diameter of articulated mechanism, when installation, can easily tapered sleeve 1 be packed in pin-and-hole, the axis of cone 5 is packed in tapered sleeve 1, the axis of cone 5 arrives after preposition again, because axially running through and be provided with strip gab 6 along it on the sidewall of tapered sleeve 1, tapered sleeve 1 is under the axial compression power effect of the axis of cone 5, opening 6 slightly opens, and makes the external diameter of tapered sleeve 1 can increase to predetermined tolerance range, makes tapered sleeve 1 external diameter reach usage requirement.Adjust by the quantity that increases or reduce adjustment pad 2 axial position that the axis of cone 5 packs tapered sleeve 1 into, slightly adjust the external diameter tolerance of tapered sleeve 1, make the external diameter of tapered sleeve 1 reach the external diameter tolerance range of installation requirement.
Disassembly sequence is the opposite sequence of installing, and pulls down after the axis of cone 5, can easily take out tapered sleeve 1, reaches the object of quick mounting and dismounting bearing pin.This combined bearing pin is convenient to installation and removal, has the adjustable advantage of external diameter, and its external diameter can change in installation and removal process, plays the effect of quick mounting and dismounting.Have wide range of applications, be particularly useful for bearing in the articulated mechanism of heavy load and tangential force load.
In the utility model, can pass through existing techniques in realizing without the technical characteristics of describing, not repeat them here.The foregoing is only preferred embodiment of the present utility model; the utility model is not limited in above-mentioned embodiment; variation, remodeling, interpolation or replacement that those of ordinary skill in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
