Description
Technical field
The utility model belongs to electric motor end cap technical field, more particularly to a kind of electric motor end cap.
Background technology
The main function of electric motor end cap is the support of the fixation and rotor for motor, is removed outside the main function of end cap,
The moulding of electric motor end cap and material or motor cost, the key factor of electric property, electric motor end cap can be divided into from structure：
Opening and enclosed type end cap.The motor of opening end cap is mainly used in inside electrical equipment, ambient humidity is relatively low, dust is dirty
In the relatively low working environment of dye degree；The motor of enclosed type end cap commonly used in working environment it is exposed in extraneous place, it is necessary to
Itself possesses certain water proof and dust proof ability.The material of end cap is generally aluminium, aluminium casting, cold punching steel, plastics, bakelite etc., can root
It is used according to the budget of motor cost, use environment requirement and mechanical engagement accuracy request class to distinguish selection.
Existing style of opening end cap motor adds the modes such as venthole, air channel on the basis of being based primarily upon enclosed type end cap
It realizes the opening pattern of end cap, to realize the natural heat dissipation demand of motor, reduces motor temperature rise；But it can not realize electric motor end cap
Cost price reduction maximizes, product structure optimizes.
Utility model content
In order to solve the technical issues of existing, the utility model provides a kind of electric motor end cap, including end cap body, strengthens
Muscle and the end cap fixed ear for being distributed on end cap body periphery, end cap body are the disc structure of indent, and end cap body includes bearing
Seat, motor fixing hole, stator installation seat and stent；Bearing seat is rolled in the center of end cap body, bearing block for installing
Pearl bearing carrys out supporting motor rotor, and bearing seat inner diameter uses die casting one-pass molding using secondary operation structure is exempted from.
Equally distributed three stents are equipped with around bearing block, stent is rectangular parallelepiped structure, and support level is set, outside stent
Side is equipped with boss, and boss is equipped with motor fixing hole, and motor fixing hole is used for the steady assembling of motor mounting surface and fitting plane；
The radial direction that end cap fixed ear and stent are distributed on end cap body is identical；Bolt hole, end cap are provided in end cap fixed ear
Reinforcing rib is provided between fixed ear and stent, ensure that the intensity of end cap fixed ear, the quantity of end cap fixed ear is three, end
Lid fixed ear carries out bolt for the upper and lower end cap of motor and is fixedly connected.
Stator installation seat is equipped on the inside of end cap body excircle, stator installation seat is used to install motor stator.
End cap body, reinforcing rib and end cap fixed ear are integrated.
Advantageous effect：
1. the utility model realizes that material saves maximization, heat dissipation effect optimizes, using one-step die casting, bearing block
Internal diameter saves part processing charges, bearing seat inner diameter size, matter is controlled by die casting using secondary operation structure is exempted from
Measure bearing seat inner diameter precision higher of the uniformity than Vehicle Processing.
2. the utility model processing technology is simple, designed using trident supporting structure so that stress is consolidated at the three of electric motor end cap
Pinpoint stress evenly, the electric motor end cap open architecture of larger area to motor stator, the maximized heat dissipation effect of rotor,
Motor is made to possess good heat dissipation effect, reduces temperature during motor work, adds the service life of motor；Product structure
It is most simplified so that electric motor end cap consumptive material reduce, saved cost.
