Description
Technical field
The utility model relates to the conveying machinery field, relates in particular to a kind of friction driven conveying system and curved section friction drive device thereof.
Background technology
Friction driven conveying system (hereinafter to be referred as the friction line) has simple in structure, stable, easy to maintenance, energy savings, low noise and does not have advantage such as greasy dirt, thereby becomes the mechanization load transfer device of a new generation.The friction line is made up of parts such as track, track switch, friction drive device, stopper, registration device, car group, detecting device, air-channel system and electric-control systems, and its process function is by the car group material to be transported to another station from a station to realize mass transport.
In the friction line, car group operation power resources are in several other actuating devices of online body are installed, they are made up of friction wheel, unpowered auxiliary wheel and drive motor etc., its principle of work is: friction wheel is by the drive motor driven rotary, and friction wheel rotates around two non-concentric centers of circle with auxiliary wheel (roller) wheel; Friction wheel and roller with the contacting in the middle of bar is clamped in of conveying carrier, utilize spring between friction wheel carrier and the wheel bracket to guarantee friction wheel, roller respectively and chassis contacts and is in impaction state between the bar by spring thus; Polyurethane material is adopted in the side of friction wheel, and there is very big friction coefficient the side that it and conveying carrier contact bar, and in the time of friction wheel from rotation, conveying carrier just moves forward under the drive of side friction power, realizes mass transport thus.
Effect was better when above-mentioned actuating device was used for the linear portion driving, be used for then existing when curved section drives dress certain defective, reason is: chassis contact bar promotes friction wheel toward the track medial movement in the time of curved section, the pulling force deficiency of spring so that roller and friction wheel move to track synchronously, cause spacing between roller and the friction wheel to contact the width of bar greater than chassis thus, thereby cause friction wheel can't compress chassis contact bar, this can make friction wheel skid and can not drive chassis by curved section.
