Abstract
A novel double-screw pump comprises a synchronous belt pulley (1), a synchronous belt pulley (2), a synchronous belt pulley (3), a double-tooth-surface synchronous belt (4) and a pump box body (5) and is characterized in that the synchronous belt pulley (1) and the synchronous belt pulley (2) are meshed with each other through the double-tooth-surface synchronous belt (4), the rotating directions of the synchronous belt pulley (1) and the synchronous belt pulley (2) are opposite so that mutual meshing of screws can be driven. The novel double-screw pump is used for replacing a pair of synchronous gears in the existing double-screw pump, so that due to the fact that the synchronous gears are eliminated, processing and meshing requirement accuracy is greatly reduced, vibration, noise and cost are lowered, gear oil of a gear tank is eliminated, the leakage link of the pump is reduced, and comprehensive mechanical performance of the pump is improved.
Description
Technical field
The present invention relates to the transmission device of two screw pump, replace synchromesh gear in the former two screw pump transmission device with bidentate face Timing Belt.
Background technique
Two screw pump is the main pump kind in the positive displacement pump, because its compact structure, the utilization ratio of unit materials is high, take up an area less, pump efficiency is higher than centrifugal pump, therefore is used widely; Because the machining accuracy of the synchromesh gear of its driving and driven screw rod of drive is higher, General Requirements carries out roll flute; And the synchromesh gear engagement also will produce heat and noise, thereby affects the comprehensive mechanical performance of two screw pump; The two screw pumps with elastic lining of Chinese patent application numbers 201010616776.8 applications, its transmission engaging member is lined with elastomer, greatly reduces processing and the engagement precision prescribed of screw rod, pump chamber, this just for the invention condition.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, and a kind of novel two screw pump is provided; Because having cancelled synchromesh gear, greatly reduce the gear oil of the processing of pump and engagement precision prescribed, the vibration that has reduced pump, noise and cost, cancellation gear-box, reduced the leakage link of pump, improved the comprehensive mechanical performance of pump; It comprises synchronous pulley 1, synchronous pulley 2, synchronous pulley 3, bidentate face Timing Belt 4, pump box body 5; It is characterized in that: synchronous pulley 1 and synchronous pulley 2 mesh by bidentate face Timing Belt 4 and by synchronous pulley 3 transmissions, and the sense of rotation of synchronous pulley 1 and synchronous pulley 2 is opposite, forms intermeshing motion; Synchronous pulley 3 is installed on the motor shaft and by bidentate face Timing Belt 4 and drives synchronous pulley 1 and synchronous pulley 2 rotations, the size of synchronous pulley 3 can be decided according to the actual applying working condition of two screw pump, can play a part to accelerate, slow down, can also play Synchronous Transmission; Simultaneously can also consider an independent Idle wheel according to actual conditions.
Engagement driving part surface in the above-mentioned mentioned two screw pump is lined with elastomer.
The Dimensions of above-mentioned synchronous pulley 1 and synchronous pulley 2 is identical.
Above-mentioned synchronous pulley 1 and synchronous pulley 2 mesh by bidentate face Timing Belt 4 and by synchronous pulley 3 transmissions, and the sense of rotation of synchronous pulley 1 and synchronous pulley 2 is opposite, forms intermeshing motion.
Above-mentioned synchronous pulley 1, synchronous pulley 2 and synchronous pulley 3 all can be used as driving wheel and use, and synchronous pulley 3 also can use as Idle wheel, perhaps can also consider to increase an Idle wheel according to actual conditions.
Advantage of the present invention is to replace a pair of synchromesh gear in the former two screw pump with bidentate face Timing Belt 4 parts such as grade, because having cancelled synchromesh gear, greatly reduces processing and engagement precision prescribed, the vibration that has reduced pump, noise and the cost of pump; A kind of novel two screw pump described in this invention, owing to do not need gear oil to lubricate synchromesh gear, thus need not consider the sealing problem of so many leakage points, so reduce the leakage link of pump; The size of synchronous pulley 3 also can be decided according to the actual applying working condition of two screw pump simultaneously, can play speed reducer, can also play Synchronous Transmission.
Description of drawings
Fig. 1 is structural representation of the present invention
Comprising synchronous pulley 1, synchronous pulley 2, synchronous pulley 3, bidentate face Timing Belt 4, pump box body 5.
Embodiment
The present invention is further described as follows below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of bidentate face Timing Belt of the present invention, and the present invention can realize in the following manner: pump drive engaging member surface is lined with elastomer, thereby guarantees do not have stuck phenomenon between the driving and driven screw rod; Synchronous pulley 1, synchronous pulley 2, synchronous pulley 3 adopt existing foundry engieering, directly casting; Bidentate face Timing Belt 4 can arrive corresponding producer and purchase.
The present invention compares with existing two screw pump, because having cancelled synchromesh gear, greatly reduce the gear oil of the processing of pump and engagement precision prescribed, the vibration that has reduced pump, noise and cost, cancellation gear-box, reduced the leakage link of pump, greatly improve the comprehensive mechanical performance of pump.
