Description
The technical field is as follows:
the invention relates to a self-aligning guide bearing structure with a retaining ring.
Background art:
the furnace water pump motor is of a vertical structure, the pump is arranged above the motor, the inner cavity of the motor is filled with high-pressure water, the guide bearing is a water lubrication bearing, and the guide bearing is arranged on the upper portion and the lower portion of the motor to play a role in guiding and is used as a rotor to limit the position in the motor cavity in the radial direction. Original direction bearing structure does not have the retaining ring, directly closes sleeve and other parts together, and unable aligning, if the clearance is inhomogeneous, long-term operation, unable formation normal water film easily leads to the bearing temperature too high, and long-term high temperature easily produces bearing inner race and axle upper shaft sleeve clearance and diminishes, embraces the axle even, leads to the motor to stop operation, causes the trouble.
The invention content is as follows:
the invention aims to provide a guide bearing structure with a retaining ring and capable of aligning, which reduces abrasion between a bearing sleeve and a shaft sleeve through automatic aligning, avoids the increase of a gap between bearings to cause vibration and swing of a motor, and ensures the stable operation of the motor.
The technical scheme of the invention is as follows:
the utility model provides a but take retaining ring aligning's direction bearing structure, sleeve (1) and bearing housing (2) are interference fit, sleeve (1) and bearing housing (2) lateral wall have the screw thread taper hole that corresponds, screw (3) and screw thread taper hole are assembled, sleeve (1) excircle flange root fillet and space installation O type circle (5) that retaining ring (4) inboard right angle formed, sleeve (1) excircle and retaining ring (4) are clearance fit, sleeve (1) excircle flange radially has corresponding cylindric hole (11) with retaining ring (4), insert cylindric lock (6) radial positioning, cylindric lock (6) radially have through-hole (10), first in motor casing (9) close bolt (13) pass through-hole (10) and heat screen (12) fixed connection, the second passes cylindric lock (6) through-hole (10) and bearing frame (8) fixed connection close bolt (7).
The working principle of the invention is as follows:
the invention relates to a self-aligning guide bearing structure with a retaining ring, which is used for bearing the radial acting force of a rotor in the running process of a motor through the elastic deformation of an O-shaped ring between a sleeve flange and the retaining ring, limiting the swing amplitude of the rotor and playing a role in buffering; wear between the bearing sleeve and the shaft sleeve is reduced through automatic centering, and the effect of elastic centering is achieved, so that the phenomenon that the motor shakes and swings due to the increase of the clearance between the bearings to influence the operation of the motor is avoided.
The invention has the technical effects that:
(1) the invention relates to a self-aligning guide bearing structure with a retaining ring, which is used for bearing the radial acting force of a rotor in the operation of a motor and limiting the swing amplitude of the rotor; the bearing clearance adjusting process plays a role in buffering in the starting and running process of the motor, and the effect of elastic centering is achieved;
(2) structurally, wear between the bearing sleeve and the shaft sleeve is reduced through automatic centering, and the service life is prolonged, so that the phenomenon that the motor shakes and swings due to the increase of the clearance between the bearings to influence the operation of the motor is avoided.
Drawings

FIG. 2 is a schematic view of a guide bearing with retaining ring of the present invention.
Detailed Description
As shown in fig. 1, a guide bearing structure with a retaining ring and capable of aligning, wherein a sleeve 1 and a bearing sleeve 2 are in interference fit, corresponding threaded taper holes are formed in the side walls of the sleeve 1 and the bearing sleeve 2, a screw 3 is assembled with the threaded taper holes, an O-shaped ring 5 is installed in a space formed by a fillet at the root of an excircle flange of the sleeve 1 and an inner side right angle of the retaining ring 4, the excircle of the sleeve 1 and the retaining ring 4 are in clearance fit, a corresponding cylindrical hole 11 is radially formed in the excircle flange of the sleeve 1 and the retaining ring 4, a cylindrical pin 6 is inserted for radial positioning, a through hole 10 is radially formed in the cylindrical pin 6, a first closing bolt 13 in a motor shell 9 penetrates through the through hole 10 to be fixedly connected with a heat shield 12, and a second closing bolt 7 penetrates through the through hole 10 of the cylindrical pin 6 to be fixedly connected with a bearing seat 8.
The guide bearing structure with the retaining ring and capable of aligning has the advantages that the upper guide bearing and the lower guide bearing can be automatically aligned, the bearing can be uniformly loaded, the local abrasion between the guide bearing and the shaft sleeve is reduced, the service life is prolonged, and the guide bearing with the adjustable center avoids the phenomenon that the motor is influenced by the vibration and swing of the motor due to the increase of the gap between the guide bearings. Therefore, the phenomena of increased rotation resistance, increased current and the like of the motor are prevented, and the radial runout of the shaft in the starting and stopping process of the motor is prevented from exceeding the standard.
