Abstract
The utility model relates to a friction clutch of disc segregator comprising a driving wheel, a friction block, a friction plate, a friction pulley and a cross axis. The driving wheel is connected with an output axis of a motor and fixed by a flat key. The friction block is fixed and connected with the driving wheel through a driving pin. The edge of the driving wheel on the friction block side is provided with a bulgy edge. A positioning pin inside the bulgy edge of the driving wheel is arranged on the friction block. The friction plate is arranged on lateral surface of the friction block. The friction pulley is cased to the friction block and contacted to the friction plate. The cross axis is arranged in an axis hole of the friction pulley through a bolt and fixed by the flat key. The utility model omitted fittings such as elastic plate, flange and connector plate, etc. of the friction clutch and driving program and reduced the number of fittings, failure rate of fittings and improved working efficiency of the friction clutch.
Description
One, technical field: the utility model relates to a kind of friction clutch.
Two, background technique: at present, the friction clutch of disk centrifuge mainly by driving wheel, resilient disc, driving pin, connect dish, connector plate, brake pad, friction plate, friction wheel, bearing and transverse axis etc. and form.Driving wheel is installed on the axle of motor, during the motor rotation, driving wheel drives the resilient disc rotation by driving pin, resilient disc drives by driving pin again and connects disc spins, connect dish and drive the connector plate rotation by bolt again, brake pad is installed on the connector plate by driving pin, and the brake pad outer side surface is equipped with friction plate, friction wheel is sleeved on the brake pad, and transverse axis passes the axis hole of friction wheel and fixedlys connected with friction wheel.When connector plate rotated, brake pad was subjected to centrifugal action and opens, and friction plate contacts with the friction wheel inner cylindrical surface, drove friction wheel by frictional force and rotated, and drove transverse axis by friction wheel and rotated, and drive the work of centrifuge vertical shaft by transverse axis.For connector plate can be contained on the transverse axis, the rotation of connector plate and friction wheel is not disturbed mutually, two bearings are installed between connector plate and transverse axis again.Resilient disc is a rubber parts, and is aging easily, and when the machine frequent starting, because the accumulation of heat, the temperature of friction clutch is very high, makes that the life-span of resilient disc is very short; Because the friction clutch actuator temperature is very high, cause the lubricating grease in the bearing to dissolve loss and damage bearing simultaneously, need often to change bearing, the friction clutch complex structure of this disk centrifuge, easily damaged parts is more, and therefore the user cost of machinery is very high, and often influences ordinary production.
Three, summary of the invention: the purpose of this utility model is to provide a kind of friction clutch of simple in structure, easy to maintenance, disk centrifuge that cost is low.
For achieving the above object, the friction clutch of disk centrifuge described in the utility model comprises: driving wheel, brake pad, friction plate, friction wheel and transverse axis, driving wheel is connected with the output shaft of motor and is fixed by flat key, brake pad is fixedlyed connected with driving wheel by driving pin, driving wheel is provided with the bead of protrusion by the edge of brake pad one side, brake pad is provided with locating stud in the bead inboard of protruding by driving wheel, friction plate is installed in the outer side surface of brake pad, friction wheel is sleeved on the brake pad and with friction plate and contacts, and transverse axis is installed in by screw in the axis hole of friction wheel and by flat key and fixes.
Owing to taked technique scheme, brake pad is directly installed on the driving wheel by driving pin, motor directly drives the brake pad rotation by driving wheel during machine startup, the friction plate of brake pad outer side surface rotates friction wheel by the inner cylindrical surface of friction friction wheel, rotate thereby drive transverse axis, make the work of centrifuge vertical shaft.It has omitted resilient disc in the existing friction clutch, has connect accessories such as dish and connector plate, omitted transmission program, reduced accessory, reduced the spoilage of accessory, improved the friction clutch working efficiency, so the advantage that the friction clutch of disk centrifuge described in the utility model has is simple in structure, easy to maintenance, cost is low.
Four, description of drawings: Fig. 1 is the friction clutch structural representation of the utility model disk centrifuge.
Five, embodiment: as seen from Figure 1, the friction clutch of disk centrifuge described in the utility model, comprise: driving wheel 2, brake pad 5, friction plate 6, friction wheel 7 and transverse axis 8, driving wheel 2 is connected with the output shaft 1 of motor and is fixing by flat key 9, brake pad 5 is fixedlyed connected with driving wheel 2 by driving pin 3, driving wheel 2 is provided with the bead of protrusion by the edge of brake pad 5 one sides, brake pad 5 is provided with locating stud 4 in the bead inboard of protruding by driving wheel 2, friction plate 6 is installed in the outer side surface of brake pad 5, friction wheel 7 is sleeved on the brake pad 5 and with friction plate 6 and contacts, and transverse axis 8 is installed in by screw in the axis hole of friction wheel 7 and is fixing by flat key 10.Motor directly drives brake pad 5 rotations by driving wheel 2 during machine startup, when brake pad 5 rotates, the friction plate 6 of brake pad 5 outer side surfaces rotates friction wheel 7 because of the inner cylindrical surface that is subjected to centrifugal action and opens friction friction wheel 7, rotate thereby drive transverse axis 8, and by the vertical shaft work of transverse axis 8 by the gear driven disk centrifuge.This scheme has been omitted resilient disc in the friction clutch of existing disk centrifuge, has been connect accessories such as dish and connector plate, omitted transmission program, reduced accessory, reduced the spoilage of accessory, improved the friction clutch working efficiency, so the advantage that the friction clutch of disk centrifuge described in the utility model has is simple in structure, easy to maintenance, cost is low.
