Abstract

The invention relates to a centrifugal pump inducer transmission device, relating to a centrifugal pump inducer. The centrifugal pump inducer transmission device is provided with an inducer and a transmission shaft, wherein the rear end of a hub of the inducer is provided with a threaded hole, the front end of the transmission shaft is provided with an external thread, and the outer thread and the thread hole work together to tightly fix the inducer on the transmission shaft. Because the rear end of the hub of the inducer is provided with the thread hole, the front end of the transmission shaft is provided with the external thread, and the outer thread and the thread hole work together to tightly fix the inducer on the transmission shaft, the centrifugal pump inducer transmission device has the advantages of simple structure and low manufacture cost, is processed and assembled by less processes, and is suitable for centrifugal pump inducers.

Description

Technical field [0001] The invention relates to a centrifugal pump inducer, in particular to a centrifugal pump inducer transmission device. Background technique [0002] We know that the existing centrifugal pump inducer transmission device is equipped with an inducer. The hub of the inducer is provided with a shaft hole in the middle of the hub. The shaft hole is provided with a transmission shaft, and the transmission shaft and the shaft hole are provided with key grooves. There is a transmission key, the front end of the transmission shaft is provided with a thread, and a shaft nut is installed on the thread, and the shaft nut fastens the inducer on the transmission shaft. This kind of centrifugal pump inducer transmission device, because there is a shaft hole in the middle of the hub, a transmission shaft is arranged in the shaft hole, a keyway is provided on the transmission shaft and the shaft hole, a transmission key is provided in the keyway, and the front end of the tra...
