Problems solved by technology

During the installation process, if the assembly gap between the impeller and the transmission shaft is not enough, generally, the method of hammering in will be used for assembly, which will damage the joint surface of the impeller and the transmission shaft and affect the assembly accuracy. During the disassembly process, It is necessary to use a jack to lift the impeller from the transmission shaft through the bracket, which is easy to damage the transmission shaft and cause the transmission shaft to be scrapped before the design life is reached

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figure 1-5 As shown, a fan 10 with a transmission shaft at a tapered end provided by an embodiment of the present invention includes a bracket 100 , a drive assembly 200 , a casing 300 , an impeller 400 , a transmission shaft 600 and an air intake duct 700 .

[0021] The material of the bracket 100 is channel steel, so that the bracket 100 has greater strength, thus can bear greater weight and provide better stability. The bracket 100 includes a first support portion 102 , a second support portion 104 and a third support portion 106 , the first support portion 102 and the third support portion 106 are connected to two sides of the second support portion 104 . The supporting surface 108 of the first supporting portion 102 is lower than the supporting surface 110 of the second supporting portion 106 . The resulting hei...

Abstract

The invention provides a fan with a conical-ended transmission shaft. The fan comprises a blade wheel and a transmission shaft. The blade wheel comprises a hub and blades fixed on the hub. The hub is provided with a conical shaft hole. The transmission shaft is provided with a conical end fixed into the conical shaft hole.

Description

technical field [0001] The invention belongs to the technical field of industrial air exhaust, and in particular relates to a fan with a transmission shaft at a tapered end. Background technique [0002] Fans are widely used in various fields of the national economy. For example, in mines and cement industries, fans work in a dusty airflow. The dust particles in the airflow will not only wear the fan, but also adhere to the fan blades. Dust accumulation, and this wear and deposition are uneven. As a result, the balance of the fan rotor is destroyed, causing the fan to vibrate, shortening the life of the fan, and affecting the normal operation of the fan. Therefore, maintenance requiring installation and disassembly of the impeller is required. During the installation process, if the assembly gap between the impeller and the transmission shaft is not enough, generally, the method of hammering in will be used for assembly, which will damage the joint surface of the impeller ...
