Description
Technical field
A kind of dead electricity clutch and brake equipment is the utility model is related to, the drum-type electromagnetism of specifically a kind of once sintered shaping loses
Electric clutch-brake clutch and brake block.
Background technology
Brake block is the critical component in drum-type electromagnetism dead electricity clutch-brake；Existing drum-type electromagnetism dead electricity clutch and brake
Device brake block, complex installation process, assembly precision are poor；All it is using traditional in the combination of friction resistance material and metallic framework
Bonding method.This method has the following disadvantages：(1) molding procedure is cumbersome；Friction resistance material shaping is first adhered to gold again
Belong on skeleton, production efficiency is relatively low.(2) friction resistance material is low with metallic framework adhesion strength；Friction resistance material and metal often occurs
Skeleton has separation obscission, and security cannot ensure.(3) high processing costs：Friction resistance material is often damaged when bonding, and leads
Cause scrappage higher, add the input of manpower and material.
Utility model content
Technical problem to be solved in the utility model is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of drum-type electromagnetism
The improvement of dead electricity clutch-brake clutch and brake block, the clutch and brake block should have installation is simple, quick, adhesion strength is high,
Service life is long and processes the characteristics of convenient.
The utility model employs technical scheme：Drum-type electromagnetism dead electricity clutch-brake clutch and brake block, including metal
Skeleton and the friction resistance material layer being bonded on metallic framework adhesive surface；Described metallic framework is by can be spliced into an annular
Two semicircular arc skeletons composition；It is characterized in that on described metallic framework adhesive surface, it is provided with toward circumferencial direction and extends
Rectangular boss；The both sides of rectangular boss symmetrically make the swallow-tail form mounting groove having for strengthening friction resistance material layer adhesion；Institute
While stating friction resistance material layer and be adhesively fixed on metallic framework adhesive surface by bonded adhesives, formation matches recessed with rectangular boss
Groove and the excrescence matched with swallow-tail form mounting groove, groove and excrescence respectively with rectangular boss and swallow-tail form mounting groove
Correspond to be adhesively fixed again after being fitted together to and be connected as a single entity.
The rectangular boss protrudes from metallic framework mounting surface 1-3mm.
The swallow-tail form mounting groove sinks to metallic framework mounting surface 2-4mm.
The beneficial effects of the utility model are：Pacify as a result of the groove matched with rectangular boss and with swallow-tail form
The excrescence structure that tankage matches, thus friction resistance material layer HTHP is injected by metal bone by once sintered moulding process
After frame adhesive surface, that is, formed the excrescence mutually chimeric with swallow-tail form mounting groove and with the groove that rectangular boss matches, add
The adhesives used between friction resistance material layer and metallic framework, it is ensured that friction resistance material has good bonding with metallic framework
Intensity and reliability, improve torque-transfer capability, brake force and the service life of clutch and brake block, and then significantly improve production
Quality, reduce production cost.In addition, also there is the characteristics of friction resistance material layer installation simple and fast and convenient processing.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is A-A in Fig. 1 to structural representation.
Embodiment
Drum-type electromagnetism dead electricity clutch-brake clutch and brake block shown in the drawings, including metallic framework 1 and be bonded in
Friction resistance material layer 2 on metallic framework；Described metallic framework is by can be spliced into two semicircular arc skeletons of an annular
Composition, friction resistance material layer is located at the outer circumference surface of metallic framework, and (outer circumference surface of two semicircular arc skeletons, which is respectively fixed with, to rub
Hinder material layer)；Above structure is similar with clutch and brake block with existing drum-type electromagnetism dead electricity clutch-brake.
The utility model is improves installation effectiveness and strengthens the adhesive strength of friction resistance material layer and metallic framework, in metal
On skeleton adhesive surface, the rectangular boss 1-1 toward circumferencial direction extension is provided with, and symmetrically make in the both sides of rectangular boss useful
In the swallow-tail form mounting groove 1-2 of enhancing friction resistance material layer adhesion；Correspondingly, the friction resistance material layer is formed by HTHP
The groove matched with rectangular boss and the excrescence 2-1 matched with swallow-tail form mounting groove, groove are corresponding with rectangular boss
Be adhesively fixed again after chimeric, excrescence also it is corresponding with swallow-tail form mounting groove be fitted together to after be adhesively fixed again.Therefore, friction resistance material layer with
The whole adhesive surface of semicircular arc metallic framework is all adhesively fixed by bonded adhesives.Obviously, what is matched with rectangular boss is recessed
Slot structure and the excrescence structure matched with swallow-tail form mounting groove, drastically increase friction resistance material layer and connect with metallic framework
Connect intensity and antistripping ability (the separation obscission for fundamentally solving friction resistance material layer).
The thickness of the friction resistance material layer can determine as needed.
The rectangular boss protrudes from metallic framework mounting surface 1-3mm；Or determine as needed.
The swallow-tail form mounting groove sinks to metallic framework mounting surface 2-4mm；Or determine as needed.
