For achieving the above object, the utility model proposes a kind of electric motor of automobile Special counterweight block, comprise body, described body lower part is provided with cambered surface, the radius of described cambered surface is 28 ~ 30mm, body upper part is provided with plane, left rounding is provided with on the left of described plane and between cambered surface, it is 1.7 ~ 2.2mm that radius of a circle is fallen on a described left side, projection is provided with on the right side of plane, the radius of described projection is 6.5 ~ 6.7mm, the distance of protruding distance of center circle plane is 2.8 ~ 3.1mm, the center of circle horizontal range of protruding distance of center circle cambered surface is 8.5 ~ 8.7mm, right rounding is provided with between the right-hand member of plane and cambered surface, it is 1.7 ~ 2.2mm that radius of a circle is fallen on the described right side.
As preferably, the center of circle of described cambered surface in the plane.
As preferably, it is 1.85 ~ 2.15mm that radius of a circle is fallen on a described left side.
As preferably, the radius of described projection is 6.52 ~ 6.68mm, and the distance of protruding distance of center circle plane is 3.01mm, and the center of circle horizontal range of protruding distance of center circle cambered surface is 8.6mm.
As preferably, it is 1.85 ~ 2.15mm that radius of a circle is fallen on the described right side.
The beneficial effects of the utility model: the utility model by arranging cambered surface, left rounding, plane, projection and right rounding on body, through experiment, optimal solution is done to structural parameters, the rotary balance of motor can be ensured, reasonable in design, manufacture simple, cost of investment is low, easy for installation, easily regulates.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the front view of a kind of electric motor of automobile Special counterweight of the utility model block.
In figure: 2-body, 21-cambered surface, the left rounding of 22-, 23-plane, 24-are protruding, the right rounding of 25-.
[embodiment]
Consult Fig. 1, a kind of electric motor of automobile Special counterweight of the utility model block, comprise body 2, described body 2 bottom is provided with cambered surface 21, the radius of described cambered surface 21 is 28 ~ 30mm, body 2 top is provided with plane 23, left rounding 22 is provided with on the left of described plane 23 and between cambered surface 21, the radius of described left rounding 22 is 1.7 ~ 2.2mm, protruding 24 are provided with on the right side of plane 23, the described radius of protruding 24 is 6.5 ~ 6.7mm, the distance of the distance of center circle plane 23 of projection 24 is 2.8 ~ 3.1mm, the center of circle horizontal range of the distance of center circle cambered surface 21 of projection 24 is 8.5 ~ 8.7mm, right rounding 25 is provided with between the right-hand member of plane 23 and cambered surface 21, the radius of described right rounding 25 is 1.7 ~ 2.2mm.The center of circle of described cambered surface 21 is in plane 23.The radius of described left rounding 22 is 1.85 ~ 2.15mm.The described radius of protruding 24 is 6.52 ~ 6.68mm, and the distance of the distance of center circle plane 23 of projection 24 is 3.01mm, and the center of circle horizontal range of the distance of center circle cambered surface 21 of projection 24 is 8.6mm.The radius of described right rounding 25 is 1.85 ~ 2.15mm.Balancing weight: the core component of electric motor of automobile.Former technique adopts slice stamping then to weld to reach use size, shortcoming: 1. rough surface, and 2. easily to produce deviation 3. production cost high for size and position degree.Now change profile shapes cold-drawn form into and improve surface smoothness, size controls by mould and is applicable to batch zero deflection to produce, and greatly reduces production cost.
