Abstract

The invention relates to the field of heavy-duty high-speed cantilever type fans, in particular to a heavy-duty high-speed cantilever type fan transmission system. Three bearings are arranged on a spindle; an NU cylindrical roller bearing is arranged at a support end; a combination of an NJ cylindrical roller bearing and a single-row angular contact ball bearing is arranged at a thrust end; an inner check ring and an outer check ring are arranged between the NJ cylindrical roller bearing and the single-row angular contact ball bearing; a spring is arranged in the outer check ring and contacted with the single-row angular contact ball bearing; each of the three bearings is fixed by a round nut and a round nut stop washer; a bearing box is provided with a left oil pool and a right oil pool;and a water channel is formed in the bearing box. Due to the technical scheme, the cantilever type fan transmission system greatly increases the using rotating speed of a fan, and expands the flow rate range and pressure range of a fan with a cantilever structure.

Description

technical field [0001] The invention relates to the field of a heavy-duty high-speed cantilever fan, and relates to a transmission system of a heavy-duty high-speed cantilever fan. Background technique [0002] Due to the cantilever installation of the impeller group of the heavy-duty cantilever structure fan, the operating speed of the fan is limited, which makes the flow and pressure range of the cantilever structure fan narrow. Contents of the invention [0003] The purpose of the present invention is to solve the problem of limiting the operating speed of the cantilever fan when the load is too large. [0004] The technical scheme of the present invention is: three bearings are installed on the main shaft, NU type cylindrical roller bearings are selected for the support end, NJ type cylindrical roller bearings and single row angular contact ball bearings are used in combination for the thrust end, and the NJ type cylindrical roller bearings An inner retaining ring and...
