The friction disc of the friction coupler is simple in structure, easy to weld, and capable of guaranteeing the quality of a welding seam after welding under the circumstance that the requirement for a welding position is guaranteed.
Description
Technical field
The present invention relates to a kind of friction coupling device friction disk, specifically a kind of friction disk that is applied to sliding friction coupling device.
Background technique
The electromechanical equipments such as mining scraper machine, Belt Conveyors for motor is engaged when starting automatically with speed reducer, automatically terminate connection when overload, mainly adopt fluid clutch or centrifugal friction clutch.
On January 25th, 2012 notice of authorization Chinese invention patent specification in " a kind of friction clutcch " (application number CN201120249906.9 is disclosed, notice of authorization CN202125546U), this friction coupler comprises main drive shaft, friction disk, clutch shell, internal spline connecting sleeve and makes friction disk axially locating and be subject to the device of axle spring pressure, in its friction disk, be provided with airtight cavity, at friction disk, be radially provided with plunger mat.
In its specification, plunger mat is not described further, plunger mat shown in the drawings be as shown in Figure 1 friction disk body cavity inside be against friction disk body cavity periphery holes on and with friction disk body be welded to connect, there is following defect in this being fixedly connected with:
Due to be friction disk body cavity inside be against friction disk body cavity periphery holes on weld, while therefore causing welding, must arrest plunger mat by a hand, the welding of another hand, but in specification, require the axis of plunger mat by the hinged axle center of adjacent two levers and the axis of rotation of friction disk, therefore this welding manner is easy to make plunger mat welded askew;
2., if welding time adopts special tooling, because be the cavity inside using at friction disk body, so welding tooling is subject to the restriction in space, make relative complex, and contrast locating is more difficult;
3. because the cavity requirement in friction disk is airtight, this welding manner is difficult to guarantee the quality of the rear weld seam of welding, is easy to produce seepage.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of friction coupling device friction disk, simple in structure, is easy to welding, and can guarantee to guarantee the weldquality after welding in situation that welding position requires.
To achieve these goals, the present invention includes friction disk body and plunger mat;
In friction disk body, be provided with airtight cavity, cavity is along the circumferential direction provided with the axis of uniform mounting hole and mounting hole through the axis of rotation of friction disk;
Plunger mat is arranged in mounting hole, and its outside dimension is slightly less than the size of the mounting hole of friction disk body, and plunger mat exterior top is provided with the positioning step of protrusion, and inside is provided with the limited step of piston rod, is provided with seal groove in intermediate hole.
Further, the quantity of plunger mat is set at least three.
Further, the quantity of seal groove is set at least two.
Further, piston seat adopts stainless steel.
Preferably, friction disk body adopts cast steel.
Compared with prior art, this friction disk adopts the mounting type of filling in plunger mat from the mounting hole of friction disk body cavity outside, because plunger mat exterior top is provided with the installation step of protrusion, and the outside dimension of plunger mat is slightly less than the size of mounting hole, therefore pass through the location of the spacing and mounting hole of installation step, the axis that plunger mat is installed rear pillar obturating plug can guarantee the axis of rotation by friction disk; Because the exterior top of plunger mat is provided with the installation step of protrusion, so install rear installation step and the radially-outer surface formation right angle of the disk body that rubs, during welding, only need weld fillet weld, easily guarantee the quality of weld seam.

In figure: 1, friction disk body, 1.1, cavity, 1.2, mounting hole, 2, plunger mat, 2.1, positioning step, 2.2, limited step, 2.3, seal groove, 3, piston rod.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, this friction coupling device friction disk comprises friction disk body 1 and plunger mat 2;
In friction disk body 1, be provided with airtight cavity 1.1, cavity 1.1 is along the circumferential direction provided with the axis of uniform mounting hole 1.2 and mounting hole through the axis of rotation of friction disk body 1;
Further, for guaranteeing that plunger mat 2 can reach good static balancing state after being welded on friction disk body 1, and jack-up plunger wherein more evenly, and then making brake pad depart from coupler inwall, the quantity of plunger mat 2 is set at least three.
Further, in order to guarantee that piston rod 3 has enough sealing effects when the interior slip of plunger mat 2, the quantity of seal groove 2.3 is set at least two.
Further, interior by liquid corrosion at the cavity 1.1 of friction disk body 1 in order to prevent piston seat, piston seat 2 adopts stainless steel.
This friction coupling device friction disk adopts the mounting type of filling in plunger mat 2 from the mounting hole 1.2 of friction disk body 1 cavity outside, because plunger mat 2 exterior top are provided with the installation step 2.1 of protrusion, and the outside dimension of plunger mat 2 is slightly less than the size of mounting hole 1.2, therefore pass through the location of the spacing and mounting hole 1.2 of installation step 2.1, the axis that plunger mat 2 is installed rear pillar obturating plugs 2 can guarantee by the axis of rotation of friction disk body 1; Because the exterior top of plunger mat 2 is provided with the installation step 2.1 of protrusion, therefore install rear installation step 2.1 and form right angle with the radially-outer surface of friction disk body 1, during welding, only need weld fillet weld, easily guarantee the quality of weld seam, can guarantee to guarantee the weldquality after welding in situation that welding position requires.
