Abstract

The utility model provides a bearing mounting structure of solar sewage pump belongs to mechanical technical field. The problem that the axial displacement of the impeller can be caused by the axial displacement of the bearing is solved. This bearing mounting structure of solar sewage pump, including motor and the pump head that mutually supports the setting, the head of motor is provided with the bearing frame and installs the bearing, is fixed with through the screw and is the annular clamp plate of circle on the terminal surface of bearing frame, and the inner ring of clamp plate is close to the downward arch of center pin hole department and forms the location strip that the round is spherical structure, and the bottom of location strip offsets with the outer lane of bearing and leans on. The utility model discloses increased fixing bearing's clamp plate structure on the bearing frame, guaranteed that the bearing can not produce axial displacement, effectively solved the sewage pump and leaded to the dead possibility of impeller displacement card because of the bearing skew, improved the reliability that the product used.

Description

Bearing mounting structure of solar sewage pump

Technical Field

The utility model belongs to the technical field of machinery, a water pump, in particular to bearing mounting structure of solar energy sewage pump is related to.

Background

Sewage pumps belong to one of the non-clogging pumps and are of various types, mainly used for conveying municipal sewage, manure or liquids containing fibers. In the submersible electric pump with the bearing outer ring anti-movement device in the prior art, the pressure plates are symmetrically arranged on the annular boss at the peripheral edge of the bearing outer ring, so that the quality problem of the water pump caused by the vertical movement of the bearing is solved, but the following problems exist, because the pressure plates are symmetrically arranged, the problem of deflection still occurs in actual production, and the end surfaces of the bearing and the bearing seat are generally not in the same plane, and most of the designs are lower than the end surface of the bearing seat, the technical effect produced by the pressing plate with the structure is not obvious.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind and compress tightly the bearing mounting structure of the solar energy sewage pump of effect better effectively having solved the bearing displacement.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a bearing mounting structure of solar energy sewage pump, is including the motor and the pump head that mutually support and set up, the head of motor is provided with the bearing frame and installs the bearing, its characterized in that, be the annular clamp plate of circle through the screw fixation on the terminal surface of bearing frame, the inner ring of clamp plate is close to the downward protruding location strip that forms the round and be spherical structure of center pin hole department, the bottom of location strip offsets with the outer lane of bearing and leans on.

In the bearing mounting structure of the solar sewage pump, the inner part of the motor is provided with the check ring, the upper end of the check ring is abutted against the stator of the motor, the lower end of the check ring is abutted against the bearing seat, and the upper end of the check ring is provided with the supporting part which is bent inwards.

In the bearing mounting structure of the solar sewage pump, the pressing plate is made of rigid plastic, and the pressing plate is preferably made of PA.

Compared with the prior art, the bearing mounting structure of the solar sewage pump is additionally provided with the pressing plate structure for fixing the bearing on the bearing seat, the bearing is guaranteed not to generate axial displacement, the possibility that the sewage pump is blocked due to the displacement of the impeller caused by the bearing offset is effectively solved, and the use reliability of the product is improved.

Fig. 3 is a schematic view of the structure of the platen.

In the figure, 1, a motor; 2. a pump head; 3. a bearing seat; 4. pressing a plate; 4a, a positioning strip; 5. a retainer ring; 5a, a support part.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, fig. 2, fig. 3, this bearing mounting structure of solar sewage pump, including motor 1 and the pump head 2 that mutually supports the setting, motor 1's head is provided with bearing frame 3 and installs the bearing, be the annular clamp plate 4 of circle through the screw fixation on the terminal surface of bearing frame 3, the inner ring of clamp plate 4 is close to the downward protruding location strip 4a that forms the round and be spherical structure of center pin hole department, location strip 4 a's bottom and the outer lane counterbalance of bearing lean on, because bearing end face and the 3 terminal surfaces of bearing frame all can have certain difference in height, the unable effectual effect that plays fixed bearing of traditional planar structure, the utility model discloses set up bellied location strip 4a on the contact surface of clamp plate 4 and bearing outer lane, the problem of difference in height when having solved clamp plate 4 and compressing tightly, the fastening nature of bearing is better after making clamp plate 4 compress tightly.

Further, the inside of motor 1 is provided with retaining ring 5, and the upper end of retaining ring 5 offsets with the stator of motor 1 and leans on lower extreme and bearing frame 3 counterbalance, and the upper end of retaining ring 5 has the supporting part 5a of inwards bending, and setting up of retaining ring 5 has played the effect of supporting the stator of motor 1 to a certain extent, because the increase of clamp plate 4 has reduced the inside space of motor 1, increases retaining ring 5 and can prevent that coil winding and clamp plate 4 from contacting and taking place the electric leakage.

Furthermore, the material of clamp plate 4 is rigid plastic, and the best material of clamp plate 4 is PA, and plastics are with low costs for the metal material, and the shaping that plasticity is strong is more convenient to plastics have the insulating effect, increase the security of sewage pump after clamp plate 4 installs.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms motor 1, pump head 2, bearing block 3, pressure plate 4, positioning strip 4a, collar 5, support 5a, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
