Description
Technical field
The utility model relates to a kind of soft start energy-saving safety coupling, belongs to actuating unit.
Background technique
Coupling is widely used in the multiple gearing, if any conveying equipments such as mine flight conveyer, Belt Conveyors, transloader, pebble mill and metallurgy, harbours as important actuating unit.Normally used is fluid coupling, utilizes the liquid medium carry-over moment, and energy consumption is big, occurs the run, drip, leak and the hydrojet problem of liquid medium easily, dangerous, easily human body is damaged, and maintenance workload is also very big, and working life is short.
The model utility content
The purpose of this utility model is to provide a kind of soft start energy-saving safety coupling, and safe and reliable, energy consumption is low, operates steadily, safeguard simple and convenient, long service life.
Soft start energy-saving safety coupling described in the utility model, its output sleeve connects shell, place, shell axle center is provided with centrifugal wheel disc, centrifugal wheel disc is provided with and radially slides pin, centrifugal is fitted on the sliding pin, is provided with mobile space between centrifugal and centrifugal wheel disc, and centrifugal radial outside is connected with brake pad, the outer ledge and the outer casing inner wall of brake pad adapt, and centrifugal wheel disc connects line shaft.
Working principle: provide rotational power by line shaft, centrifugal wheel disc rotates, and under action of centrifugal force, centrifugal and brake pad move to periphery away from centrifugal wheel disc, near outer casing inner wall, at this moment, and centrifugal wheel disc idle running, non-loaded, operate steadily, do not have and impact.When reaching certain rotating speed, brake pad is close to outer casing inner wall, and frictionally drives shell and rotates, and shell outputs power by output sleeve.When reaching rated speed, brake pad contacts and tensioner fully with outer casing inner wall, and line shaft and output sleeve rotate synchronously, thereby realizes power transmission.When working equipment seriously overloaded, brake pad can skid in the enclosure, had protected motor and operation machinery, and is safe and reliable.
Described soft start energy-saving safety coupling, it radially slides pin upwards can be distributed with 2-8 centrifugal wheel disc week, force balance, maximum friction intensity.
Described soft start energy-saving safety coupling, on line shaft, connect the spline elastic coupling flexible coupling, can further improve the interlock performance, the spline elastic coupling flexible coupling is with common the same, the spline of its active half-coupling and the spline of driven half-coupling fasten mutually, the utility model is replaced by free elastomer block with the integral, flexible piece that is lined with in the spline gap that fastens, free elastomer block is covered with the elastomer block cover, be convenient to replacing as the free elastomer block of easily damaged parts, disassemble free elastomer block cover, can directly free elastomer block be changed from radially taking out, need not to resemble to change and move motor or retarder the integral, flexible piece, change from axle head, especially for those main equipments that is difficult for moving, superiority is stronger.
Compared with prior art, the utlity model has following beneficial effect:
(1) non-loaded startup operates steadily, and does not have and impacts, and does not influence electrical network, saves electric weight, and energy consumption is low.
(2) overload protection function is strong, can effectively limit input torque during overload, avoids taking place vexed car phenomenon, and the protection motor is not damaged, and is safe and reliable.
(3) without liquid medium, conservation, Maintenance free between the spreadable life reduces workload and labor intensity, saves a large amount of manpower and materials, and user cost is low.
(4) simple in structure, volume is little, is difficult for infringement, long service life, and easy operating, easy to maintenance, the cost of repairs is low.
Can be widely used on the conveying mechanism equipment such as mine flight conveyer, Belt Conveyors, transloader, pebble mill and metallurgy, harbour, be used for the transmission of power.
Description of drawings
Fig. 1, the utility model one example structure schematic representation.
A-B-A cross section structure schematic representation among Fig. 2, Fig. 1.
Among the figure: 1, output sleeve 2, shell 3, brake pad 4, sliding pin 5, centrifugal 6, centrifugal wheel disc 7, driven half-coupling 8, elastomer block 9, elastomer block cover 10, half-coupling initiatively.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, soft start energy-saving safety coupling described in the utility model, output sleeve 1 connects shell 2, the place, axle center of shell 2 is provided with centrifugal wheel disc 6, centrifugal wheel disc 6 is provided with and radially slides pin 4, radially slide pin 4 and upwards can distribute 2-8 centrifugal 6 weeks of wheel disc, in the diagram be 6, be fitted in for centrifugal 3 on the sliding pin 4, centrifugal 5 and centrifugal 6 on wheel disc are provided with mobile space, and centrifugal 5 radial outside is connected with brake pad 3, and the inwall of the outer ledge of brake pad 3 and shell 2 adapts, be cambered surface, centrifugal wheel disc 6 connects line shaft.
Can connect the spline elastic coupling flexible coupling again on the line shaft, further improve the interlock performance, the spline of the active half-coupling 10 of spline elastic coupling flexible coupling and the spline of driven half-coupling 7 fasten mutually, be lined with free elastomer block 8 in the spline gap that fastens, free elastomer block 8 is covered with elastomer block cover 9, encapsulates the location.The same with common spline elastic coupling flexible coupling, the spline of its active half-coupling 10 and the spline of driven half-coupling 7 fasten mutually, the utility model is replaced by free elastomer block 8 with the integral, flexible piece that is lined with in the spline gap that fastens, and can change from radially taking out separately.
During work, give initiatively half-coupling 10 input power by power equipments such as motor, give centrifugal wheel disc 6 by driven half-coupling 7 with transmission of power again, centrifugal wheel disc 6 rotates, under action of centrifugal force, centrifugal 5 and brake pad 3 move to periphery away from centrifugal wheel disc 6, near the inwall of shell 2, during this period, centrifugal wheel disc 6 idle running.When reaching certain rotating speed, brake pad 3 is close to the inwall of shell 2, and frictionally drives shell 2 and rotates, and shell 2 outputs power by output sleeve 1.When reaching rated speed, brake pad 3 contacts and tensioner fully with the inwall of shell 2, and line shaft and output sleeve 1 rotate synchronously.When working equipment seriously overloaded, brake pad 3 can skid in shell 2, had protected motor and operation machinery, and is safe and reliable.
