Abstract
The utility model discloses a centrifugal friction coupler. The coupler comprises a drive coupler, a driven coupler, a connection sleeve, a machine core, three centrifugal friction blocks, bearings and a casing. The drive coupler is connected with the driven coupler through the connection sleeve, the machine core is arranged on the driven coupler, the three centrifugal friction blocks are evenly distributed on the machine core, the bearings are arranged at gap positions of the casing and the driven coupler, and antistatic abrasion-resistant material layers are arranged on the centrifugal friction blocks. The centrifugal friction coupler has the advantages that the three centrifugal friction blocks are evenly distributed, so that the centrifugal force can be adjusted timely, and the transmission requirement of large-power mechanical equipment is met; meanwhile, by arranging the antistatic abrasion-resistant material layers on the centrifugal friction blocks, risks caused by the temperature rising on the surfaces of the centrifugal friction blocks can be prevented, and the service life is effectively prolonged.
Description
Technical field
The utility model relates to a kind of coupler, specifically a kind of centrifugal type friction coupling device.
Background technique
Coupler belongs to mechanical spare part in common use category, it is a part for mechanical transmission, Main Function is that the axle of motor and work mechanism is linked up and transmitting torque, and the radial and axial error can two axles of adequate compensation causing because of factors such as manufacture, installations.Mining equipment Belt Conveyors, scraper conveyor are all to use fluid coupling all the time.Fluid clutch is to be filled with liquid medium in clutch inner chamber part, when motor band dynamic clutch rotates, and the turbine wheel blade of liquid medium impact clutch under the effect of centrifugal force, thus drive output shaft rotation.Fluid clutch is owing to generally usining oil or the water Transfer Medium as power, and easy generation high temperature in service causes that oil or water expand, boost, and causes being arranged on the fusible plug fusing on clutch outer member; oil, water are revealed; finally cause shutting down, impact normal operation, so working life is shorter.
In the last few years, centrifugal friction Coupler, as new generation product, was considered to the ideal substitute of hydraulic couplers, and was constantly promoted use.But, current centrifugal type friction coupling device is the cylinder that a suit centrifugal-block is set on passive half-coupling mostly, when active half-coupling rotates, centrifugal-block can tightly be pressed in due to the effect of centrifugal force on the inner peripheral surface of passive half-coupling cylinder, but because centrifugal-block is limited in cylinder, cannot adjust centrifugal force, rubbing surface can not increase, transmitted power is little, thereby cannot meet the transmission requirement of high-power machinery equipment; Meanwhile, because the in use friction of centrifugal-block is easy to cause surface temperature too high, if used, very easily cause gas explosion under ore deposit, abnormally dangerous, and so also can affect its working life for a long time.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of centrifugal type friction coupling device, can regulate centrifugal force, and transmitted power is high, the danger that can avoid the temperature due to centrifugal friction piece surface to raise and cause simultaneously, and long service life.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of centrifugal type friction coupling device, comprise initiatively coupling, driven coupling, connecting sleeve, movement, centrifugal friction piece, bearing and housing, initiatively shaft joint is connected with driven coupling by connecting sleeve, movement is positioned on driven coupling, centrifugal friction piece is installed on movement, gap location at housing and driven coupling is provided with bearing, the quantity of described centrifugal friction piece is three, three centrifugal friction pieces are evenly distributed on movement, described centrifugal friction piece is provided with anti-static and abrasion-resistant material layer.
Preferably, described bearing is copper sheathing bearing, has long feature of high-mechanic and life-span.
Further, on described bearing, be provided with seal ring.
Preferably, described housing and centrifugal friction piece all adopt spheroidal graphite cast iron, and spheroidal graphite cast iron has the performance of high strength, corrosion-resistant, high temperature resistant or low temperature, anti-mechanical shock.
The beneficial effects of the utility model are: adopt three centrifugal friction pieces to be uniformly distributed, while centrifugal friction piece is made cylindrical piston formula with movement and is coordinated, can adjust in time centrifugal force, greatly reduce the relative vibration of centrifugal friction piece and movement in working procedure, thereby can meet the transmission requirement of high-power machinery equipment; Meanwhile, by anti-static and abrasion-resistant material layer is set on centrifugal friction piece, can avoid the danger that raises and cause due to the temperature on centrifugal friction piece surface and the working life of effectively having improved centrifugal friction piece.
