Abstract
Based on accurate analyzing and calculating running load of straight coupled motor in use for pump, the invention modifies structure of duplex bearing in traditional configuration to single bearing structure at extended end of motor shaft. The single bearing receives radial force mainly. Based on magnitude of radial force, deep groove ball bearing or cylindrical roller bearing. Based on different installation modes, deep groove ball bearing or angular contact ball bearing is selected respectively for fan end. The selected bearing receives axial force mainly. The bearing at fan end is selected as bearing of fixed end.
Description
Technical field
The present invention is a kind of collocation method of bearing, refers to one step single sucking tubing pump extension shaft motor bearings collocation method especially.
Background technology
Pump is different from standard electromotor with direct connection extension shaft motor, the motor external load that also main bearing pump running brings when bearing self load; Therefore the motor bearings configuration is different from standard electromotor.At present, domestic one step single sucking tubing pump is joined direct connection extension shaft motor bearings and is configured to: motor shaft extension end adopts dual bearing structure, i.e. an angular contact ball bearing and deep groove ball bearing pairing used; Fan end adopts a deep groove ball bearing, adopts the shaft extension end as stiff end.There is following shortcoming in this bearing configuration: the configuration of duplex bearing has reduced the limit speed of bearing, has reduced transmission accuracy; The long-term use of pad between duplex bearing is yielding, and bearing is fragile; Angular contact ball bearing bears axial force and radial load simultaneously in this structure, damages easily; Deep groove ball bearing radiating condition in the duplex bearing is bad, and influence is used; Cost is higher; Assembling inconvenience.Adopt the motor of this bearing configuration often to occur bad phenomenon such as noise is big, bearing heating in use, even cause the serious consequence that causes burn-down of electric motor because of the bearing locking.
Summary of the invention
The present invention is in order to improve the reliability of pump with straight coupled motor, to reduce product cost, a kind of one step single sucking tubing pump extension shaft motor bearings collocation method being provided.
The present invention is for overcoming the above problems, improve the reliability of loading ability of bearing, reduce product cost simultaneously, on the basis that pump is calculated with direct-coupled electrical machinery performance load Accurate Analysis, configuration is improved to traditional bearing: change pump into single bearing structure with straight coupled motor shaft extension end dual bearing structure, the main bearing radial force of this bearing, and select deep groove ball bearing or cylinder roller bearing respectively for use according to the size of radial load; Fan end adopts deep groove ball bearing or angular contact ball bearing structure respectively according to the mounting means difference, and this bearing mainly bears axial force; Select for use the fan end bearing as the stiff end bearing.
