Abstract
The utility model discloses a rotation resistance testing equipment for supporting roller in belt conveyer, which adopts two full floating air bearings 3 to support a compound frame 2 which sticks the mandrel of a supporting roller 2. When the bearing is ventilated to form an air cushion, the entire compound frame 2 floats freely and obtains three-dimensional displacement and free fine adjustment of the degree of rotational freedom, and the pressure ratio difference between the air cushions can automatically balance the additional resistance; when the supporting roller bears radial load and are rotated by friction, the supporting roller drive the entire compound frame to rotate freely to touch a sensor 4, which can measure the rotation resistance of the supporting roller. The utility model has the advantages of small additional resistance, absorption of shock and high testing precision, and is suitable for testing the rotation resistance of rollers, drums, etc.
Description
The utility model is a kind of test unit of testing the single roller revolving resistance of belt conveyor.Carrying roller is the belt conveyor critical piece, and its rotational resistance value directly influences power consumption, also is one of product quality leading indicator.General test requires carrying roller to simulate under the operating mode in specified radial load and linear velocity to rotate, and measures in the roller that is overcome the rotational resistance that friction and structure off-centre cause between rolling bearing, seal, grease.This value is less, is difficult for surveying accurate.
Known test unit is the two of adopting knife edge bearing supporting carrying roller axle.Owing to be subjected to workmanship, the influence of mounting process, between two knife edge bearing and the carrying roller axle center line all be difficult to guarantee concentric, thereby in test the not little additional drag of existence, directly influence test accuracy, deviation is bigger.
The utility model proposes roller revolving resistance test unit a kind of novelty, that accuracy is high.The axle 9 of tested carrying roller 1 is clamped on the chuck 10 of group frame 2, framework two ends shaft 11 is concentric with the carrying roller axle, and seat is on two semicircle type air bearing 3, and this air bearing passes to after certain air pressure forms air cushion, whole frame strip the free levitating of carrying roller, it can obtain the trace of three-D displacement and rotational freedom and automatically adjust, the pressure ratio balance that forms by the air-cushion gap size additional drag of all directions.When being subjected to movement weight rod 6, pinch roller 5 does to press to carrying roller in order to certain radial load.And, the idler roll skin is rotated around its axle with certain peripheral speed by friction gearing by motor 7 driving-belts 8 transmission pinch rollers 5, and simultaneously, carrying roller drives whole framework and rotates without restrictions around the air bearing garden heart, and the sensor 4 with being fixed on the frame records rotational resistance.Because additional drag is minimum, and intussusception vibration, the measuring accuracy height, this device precision can reach 0.1%, wherein accompanying drawing is:
Fig. 1: rotational resistance test unit front view,
Fig. 2: rotational resistance test unit side view,
Fig. 3: rotational resistance test unit vertical view.
Claims (3)
1, belt conveyor roller revolving resistance test unit, it is made up of following parts: air bearing 3, framework 2 and sensor 4, it is characterized in that adopting the two axial ends 11 of a framework 2 of a pair of air bearing 3 supportings, framework dop 10 clamps the axle 9 of tested carrying roller 1, sensor 4 is positioned at the front upper place of framework, after the bearing ventilation forms air cushion, the free levitating of whole framework, when carrying roller 1 is rotated by friction, it drives whole framework simultaneously and rotates without restrictions and contact sensor 4, records roller revolving resistance.
2, according to the belt conveyor roller revolving resistance test unit of claim 1, it is characterized in that two air bearing adopt semicircle type bearing shell 12 and smooth garden cambered surface base 13, it increases whole gimbal freedom.
3, according to the belt conveyor roller revolving resistance test unit of claim 1, it is characterized in that framework adopts adjustable group frame, clamp carrying roller different in size to adapt to.
