Description

Technical Field

[0001] The utility model relates to the technical field of motor installation, in particular to a motor installation backlash eliminating tool. Background Art

[0002] The axial clearance of an electric motor refers to the fit clearance between the stator and rotor of an electric motor. The main reasons for the existence or generation of the axial clearance of an electric motor are as follows, such as the cumulative error of parts. The rotor and stator are composed of multiple parts, and the size of each part has tolerances. The cumulative error after assembly forms the initial axial clearance, or the shaft is stuck. When the axial clearance is small or zero, the bearing clearance will be reduced due to extrusion, which will cause the bearing to rotate inflexibly when the motor is working, thereby affecting the performance of the motor; or the thermal expansion of the material. The bearings, stator, and rotor expand due to heat when the motor is working. Due to the difference in the thermal expansion coefficient of the material, when the axial clearance is small or zero, the bearing clearance will be reduced due to extrusion, which will cause the bearing to rotate inflexibly or even stall when the motor is working, thereby affecting the performance of the motor. Therefore, for the motor to work normally, it must have a suitable axial clearance. However, most existing motors cannot remove the anti-backlash tooling horizontally after adjusting the axial clearance during installation, which makes it easy to skew and damage the machine. Therefore, there is a special need for a motor installation anti-backlash tooling.

[0003] However, during the installation process of most existing motors, it is impossible to remove the anti-backlash tooling horizontally after adjusting the axial clearance. If the staff or the machine does not handle the anti-backlash tooling improperly when removing it, it is easy for the anti-backlash tooling to tilt or fall, causing damage to the anti-backlash tooling or the motor, and the need to eliminate the clearance again.

[0021] The lifting mechanism 3 includes a hook 301, a fixed plate 302, a limit plate 303, a lifting column 304, a limit block 305, a gear 306, a rotating shaft 307 and a second motor 308. The inner surface of the first top cover 4 is equipped with a hook 301, the upper surface of the hook 301 is fixedly connected to the fixed plate 302, the upper surface of the fixed plate 302 is fixedly connected to the limit plate 303, one side surface of the limit plate 303 is fixedly connected to the lifting column 304, the lower surface of the lifting column 304 is fixedly connected to the limit block 305, the outer surface of the lifting column 304 is equipped with a gear 306, the inner surface of the gear 306 is equipped with a rotating shaft 307, and one end surface of the rotating shaft 307 is equipped with a second motor 308. When the lifting column 304 is lifted and lowered, the lifting column 304 is lifted and lowered.

[0022] Furthermore, the hooks 301 are distributed at equal intervals on one side surface of the fixed plate 302, and the outer wall size of the fixed plate 302 is consistent with the inner wall size of the first top cover 4. Through the setting of the hooks 301, the force can be more evenly distributed when the pull rope 5 is pulled, preventing a single hook 301 from breaking and causing losses.

[0023] Furthermore, the outer wall size of the limit plate 303 matches the inner wall size of the first top cover 4, and the outer wall size of the lifting column 304 matches the inner wall size of the gear 306.

When the first motor 8 needs to be fixed upright to perform the gap eliminating work, the first motor 8 is first placed on its side, and then the fixing ring 903 is engaged to the appropriate position below the first motor 8. Then, the mounting block 904 is installed into the connection of the fixing ring 903 using a tool, and then the bolt 905 is inserted into the mounting block 904 using a tool and tightened with a hammer, and then the limiting ring 906 is inserted into the mounting block 904 to prevent the mounting block 904 from falling. After the installation is completed, the anti-slip pad 901 is installed on the foot of the bracket 902, and the first motor 8 can be placed upright in the appropriate position of the base 1.
