Detailed Description
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 shows a schematic structural diagram of a preferred embodiment of the invention, an inert deceleration roller for a belt conveyor comprises a roller shaft, a roller body, a gland, a self-aligning roller bearing a, a flat washer, a spring washer, a hexagon head bolt, a vertical bearing seat, a self-aligning roller bearing b, an elastic retainer ring for a shaft and an encapsulating layer; the roller shaft structure is characterized in that vertical bearing seats are arranged at two ends of the roller shaft, a self-aligning roller bearing and a shaft circlip are arranged on the roller shaft, the shaft circlip is secondarily connected with the roller shaft, the upper end of the self-aligning roller bearing is matched with the roller body in a built-in mode, the self-aligning roller bearing is connected with the roller shaft, a gland is connected to the outer side of the self-aligning roller bearing, and the gland is connected with the roller body through a spring washer and a hexagon bolt. The flat gasket is fixed on the outer side of the gland. And a framework oil seal is arranged in the gland. The framework oil seal is an internally wrapped framework oil seal. The outer side of the roller body is provided with an encapsulating layer. The material of the encapsulating layer is polyurethane. The elastic retainer ring for the shaft is a retainer ring for a single-hole shaft. The vertical bearing seat is made of stainless steel. The inner hole of the self-aligning roller bearing is cylindrical or conical.
The driving mode of the invention is that the motor drives the speed reducer, the speed reducer drives the roller, the roller drives the belt, and the belt drags the bend roller to realize transmission closed loop. Because the roller is designed to start without load, two layers of bearing transmission torque are arranged between the roller shaft and the roller body to form two-stage speed change and stepless speed regulation, the speed of the motor reducer shaft which is suitable for the belt conveyor to drive the roller is different from that of the roller body, two pairs of bearings are adopted between the roller body and the roller shaft to support and transmit, a differential speed change mechanism is formed by superposition, in the process of electrically driving the belt and transmitting the belt to the roller, the load of the belt is changed in a curve manner, the acting force of the belt to the roller in the transmission process is also changed, the roller is correspondingly required to be changed in speed, and the roller forms an inertia speed reduction ratio to the roller shaft because the two pairs of bearings are coupled to act on the roller and the roller shaft.
The invention overcomes the problems of large belt load resistance, different speeds of the roller and the belt and easy slippage of the belt in the prior art, and provides the roller which can integrally form inertia speed reduction by keeping the same speed of the belt and the roller and the same speed of a motor reducer and a roller shaft so as to meet the requirement of belt speed variability during the carrying of a belt conveyor. The belt conveyor has the advantages that after a belt is loaded, the roller rotates fast, the belt rotates slowly, the belt and the roller body are enabled to be synchronous at a high speed, the belt and the roller body do not slip or deviate, the transmission power of the belt to the roller is saved, as long as the belt drives the roller body to rotate synchronously, the roller shaft can be decelerated properly, the driving power is saved, the structure of the whole machine is simplified, and the structure of the whole roller is more compact. Furthermore, the invention adopts the structural characteristics of double-layer bearings of the roller and inertia deceleration, the automatic deviation adjustment can be realized during the running of the belt, if one side of the belt with load deviates, the tension of the belt on the other side changes, the transmission on the two sides of the roller quickly generates differential motion, the bearing on the side with large motion resistance rotates passively, the bearing on the side with small motion resistance generates differential motion, the roller slows down, the resistance of the belt on the side with slow speed of the roller increases, the resistance is transferred to the side, the roller automatically corrects the deviation, the deviation adjustment by the roller can effectively solve the deviation problem of the rubber belt of the existing long-distance belt conveyor, and the invention can be widely applied to the deviation correction of various belt conveyors.
