Abstract
A non-radial force transmission device used for pumps. The utility model is comprised of a first pulley and a second pulley, the first pulley is connected with the pulley tensioning device, the first pulley and the second pulley are connected through belts, the second pulley is arranged on the outer periphery of the pulley seat through a bearing, a shaft coupling device is connected on the upper end surface of the second pulley, a step is arranged on the outer periphery of the lower part of the pulley seat, and a thrust bearing is arranged between the lower end surface of the second pulley and the step surface of the pulley seat. The first pulley is connected with the output axle of the motor, and the shaft coupling device is connected with the pump axle. The axial force is born by the thrust bearing, the belt pre-tensioning force is transmitted onto the pulley seat through a bearing, and the transmission axle doesn't bear the radial force. The stress situation of the transmission axle is identical to the transmission axle in the direct transmission method, the same axle diameter can be adopted, the relevant parts such as bearing parts, packing material parts, guiding bearing parts, etc. are completely identical, which can be replaced, the cost is reduced, and the benefit is remarkably enhanced.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pump, the particularly power transmission mechanism of pump, and concrete is a kind of no radial force belt drive unit that is used for the pump machine.
Background technique:
The kind of drive of vertical-type axial-flow pump and mixed flow pump adopts the belt transmission or the direct kind of drive.In the belt transmissioning mode, during the pump running, axial force is born by the thrust-bearing on the belt pulley, the pretightening force of belt is also born by transmission shaft, the moment of flexure that transmission shaft bears bigger axial tension simultaneously and produced by pretightening force, so the diameter of transmission shaft is bigger than the direct transmission drive shaft diameter of respective model.And directly transmission drive shaft only bears axial force.Therefore the diameter of axle of belt transmission and the transmission shaft that directly adopts in the kind of drive is different, and correlated parts such as bearing part, packing elements, guide bearing parts equidimension difference are big, can not be general, and cause cost to increase, benefit decline.
Summary of the invention:
The purpose of this utility model provides a kind of no radial force belt drive unit that is used for the pump machine, and the described this no radial force belt drive unit that is used for the pump machine will solve the technical problem that can not adopt the transmission shaft of the identical diameter of axle in prior art belt transmission and the direct kind of drive.
This no radial force belt drive unit that is used for the pump machine of the present utility model is made of one first belt pulley and one second belt pulley, described first belt pulley is connected with a pulley tensioner, first belt pulley is connected by belt with second belt pulley, wherein, described second belt pulley is arranged on the excircle of a belt wheel seat by bearing, be fixedly connected with a coupling in the upper-end surface of second belt pulley, the bottom excircle of belt wheel seat is provided with step, is provided with thrust-bearing between the step surface of the lower end surface of second belt pulley and belt wheel seat.
Further, the downside of described belt wheel seat is provided with a base, and the belt wheel seat is fixedlyed connected with described base by bolt.
Further, place, the axle center of described belt wheel seat is provided with axis hole, is provided with axle in the described axis hole.
Further, be provided with axle in the described coupling.
Concrete, pulley tensioner described in the utility model and coupling all adopt prior art, and about pulley tensioner and coupling technological scheme in the prior art, those skilled in the art all understands, so do not repeat them here.
Working principle of the present utility model is: first belt pulley is connected with the output shaft of motor, and coupling is connected with the pump shaft of vertical-type axial-flow pump or mixed flow pump.When vertical-type axial-flow pump, mixed flow pump running, axial force is born by the thrust-bearing that the second belt pulley lower end is provided with, and the belt prefastening force is delivered on the belt wheel seat by radial bearing, makes the not effect of bearing radial force of transmission shaft.Therefore the stressing conditions of its transmission shaft is identical with transmission shaft in the direct kind of drive, can adopt the identical diameter of axle, and correlated parts such as bearing part, packing elements, guide bearing parts etc. are identical, can exchange cost decline, remarkable benefit raising.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is in belt gear, utilize the thrust-bearing that is connected with belt pulley to bear the axial force that the pump shaft running produces, utilize radial bearing that the belt prefastening force is delivered on the belt wheel seat by radial bearing, make the not effect of bearing radial force of transmission shaft, therefore the stressing conditions of its transmission shaft is identical with transmission shaft in the direct kind of drive, can adopt the identical diameter of axle, correlated parts such as bearing part, packing elements, guide bearing parts etc. are identical, can exchange, cost descends, and remarkable benefit improves.
