Abstract
The invention discloses a restraining structure of a motor end cover mounting leg and a support column. The restraining structure comprises the motor end cover mounting leg and the support column, wherein a concave platform is arranged at an end leg part of the motor end cover mounting leg; a fixed column is arranged on the concave platform; a through hole penetrating through the fixed column and the concave platform is formed in the center of the fixed column; the lower end of the support column is fixedly arranged on an iron core; and the upper end of the support column penetrates out of the through hole, and is tightly locked on the fixed column by a nut. According to the restraining structure of the motor end cover mounting leg and the support column, radial stress of an end cover can be restrained effectively, and the perpendicularity can be restrained under the condition that an area of a contact end face of the motor end cover mounting leg is not increased.
Description
Technical field
The present invention relates to the fixed structure of electric motor end cap, the restraining structure of especially a kind of electric motor end cap installation foot and support column.
Background technology
The fixed structure of prior motor end cap installation foot and support column, the end face that is constrained to the electric motor end cap installation foot of its electric motor end cap installation foot.For fastening purpose, can only increase the support column axial cross section as far as possible at present, guarantee the constraint of support column and electric motor end cap installation foot plane verticality.Because support column and electric motor end cap installation foot contact-making surface area are limited, the electric motor end cap installation foot only is subjected to the part constraint, can not the stressed and perpendicularity of more effective constraint electric motor end cap radial direction.
Summary of the invention
The objective of the invention is to: the restraining structure of a kind of electric motor end cap installation foot and support column is provided, can be under the situation that does not increase electric motor end cap installation foot contact face area, the operative constraint end cap radial direction is stressed, solution perpendicularity restricted problem.
For achieving the above object, the present invention can take following technical proposals:
The restraining structure of a kind of electric motor end cap installation foot of the present invention and support column, comprise electric motor end cap installation foot, support column, the end foot of described electric motor end cap installation foot is provided with the depression platform, on described depression platform, be provided with fixed leg, the center of described fixed leg is provided with the through hole that connects this fixed leg and depression platform, the lower end of described support column is fixedly arranged on the iron core, its upper end passes described through hole and by nut check on fixed leg.
Between described nut and fixed leg, be provided with packing ring.
The structure that sets firmly of described support column and iron core is: the lower end of support column tightly fits in the installing hole of iron core.
Compared with prior art the invention has the beneficial effects as follows: owing to adopt technique scheme, the end foot of described electric motor end cap installation foot is provided with the depression platform, on described depression platform, be provided with fixed leg, the center of described fixed leg is provided with the through hole that connects this fixed leg and depression platform, the lower end of described support column is fixedly arranged on the iron core, its the upper end pass described through hole and by nut check on fixed leg, this structure, the fixed leg inwall has constraint to the support column outer wall, and (the constraint tolerance clearance is 0.015～0.04mm), increase the constraint of end cap installation foot radial constraint and perpendicularity, improved the bond strength of end cap installation foot and support column.
