Abstract
The utility model provides a ventilation channel, and in particular relates to a high efficient ventilation channel which is applied to a motor. The ventilation channel comprises a steel body. Concave assembly gaps are respectively arranged on two side ends of the steel body. The cross section of each assembly gap is ladder-shaped. The transverse thickness of the middle of the steel body is 2/5 to 3/5 of the total transverse thickness. A rust-proof layer is arranged on the surface of the steel body. The high efficient ventilation channel has the advantages of simple assembly, prolonged service life and excellent performance.
Description
Technical field
The utility model is a kind of ventilation steel channel, and particularly a kind of dynamical ventilation steel channel, for motor.
Background technology
Ventilation steel channel of the prior art is mainly used in the auxiliary products on generating equipment, and traditional ventilation steel channel needs a lot of cutting steps, make ventilation steel channel and cold drawn motor between technical parameter be difficult to reach a higher requirement, and expensive.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, provides a kind of assembly precision high, has the dynamical ventilation steel channel of antirust function simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of dynamical ventilation steel channel, comprise the steel body, the two side ends of described steel body is respectively equipped with the assembling breach of inner concavity, the cross section of described assembling breach is trapezoidal shape, the transverse gage of described steel body interposition accounts for 2/5～3/5 of total transverse gage, and the surface of described steel body is provided with antirust coat.
As preferably, in described assembling breach, the angle of inclination of hypotenuse is 30 °～60 °, between described steel body and assembling breach, by the transition of circular arc phase, is connected.
As preferably, the assembling breach of described steel body two side ends is symmetry shape and distributes, and described steel body is the nickel chromium stainless steel part.
Therefore, a kind of dynamical ventilation steel channel of the present utility model, provide a kind of assembling easy, increases the service life, and performance is outstanding.
The accompanying drawing explanation
Fig. 1 is section structure schematic diagram of the present utility model.
