Description
Technical field
The utility model is related to motor technologies, more particularly to a kind of technology of electric motor end cap bearing chamber.
Background technology
Bearing chamber is to be commonly installed on motor for accommodating rotor bearing and a part of the work that can run well
On former and later two end caps of motor.All loads of motor and weight are undertaken by bearing chamber, in order to meet motor operation
Required necessary requirement of mechanical strength, the cavity wall of the bearing accommodating cavity of existing electric motor end cap bearing chamber all use thicker and real
The rigid of the heart, this thick and solid cavity wall provide reliable mechanical strength for motor；But it is generated when rotor bearing operating
Heat influenced without easily distributing because of the thick and solid cavity wall by bearing accommodating cavity.
Utility model content
Defect present in for the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a kind of machines
Tool intensity is high, and the electric motor end cap bearing chamber of good heat dissipation effect.
In order to solve the above-mentioned technical problem, a kind of electric motor end cap bearing chamber provided by the utility model, including bearing chamber
Ontology, bearing chamber ontology are equipped with the bearing accommodating cavity for accommodating rotor bearing, it is characterised in that：
The circular radiating slot for enclosing around bearing accommodating cavity one and unidirectionally opening to the right is formed on the bearing chamber ontology,
And the inside cell wall of radiating groove is made of the cavity wall of bearing accommodating cavity, and multiple cooling fins, each cooling fin are fixed in radiating groove
It is symmetrically laid around bearing accommodating cavity, the inner side edge edge of each cooling fin is affixed with the inside cell wall of radiating groove, outside each cooling fin
Side is along affixed with the outside cell wall of radiating groove.
Further, the width of the radiating groove is incremented by from left to right.
Electric motor end cap bearing chamber provided by the utility model is cooperatively formed using each cooling fin and external groove sidevall in radiating groove
Case type structures rigid support is provided, while also adding heat dissipation area, have the characteristics that high mechanical strength and good heat dissipation effect.
Description of the drawings
Fig. 1 is the main structure diagram of the electric motor end cap bearing chamber of the utility model embodiment.
Specific implementation mode
The embodiments of the present invention are described in further detail below in conjunction with description of the drawings, but the present embodiment and are not had to
In limitation the utility model, every similar structure using the utility model and its similar variation should all be included in the utility model
Protection domain, the pause mark in the utility model indicates the relationship of sum.
As shown in Figure 1, a kind of electric motor end cap bearing chamber that the utility model embodiment is provided, including bearing chamber ontology,
Bearing chamber ontology is equipped with the bearing accommodating cavity 1 for accommodating rotor bearing 5, it is characterised in that：
The circular radiating for enclosing around bearing accommodating cavity 1 one and unidirectionally opening to the right is formed on the bearing chamber ontology
Slot, and the inside cell wall 2 of radiating groove is made of the cavity wall of bearing accommodating cavity 1, multiple cooling fins 4 is fixed in radiating groove, respectively
Cooling fin 4 is symmetrically laid around bearing accommodating cavity 1, and the inner side edge edge of each cooling fin 4 is affixed with the inside cell wall 2 of radiating groove, respectively
The outer side edges of cooling fin 4 are along affixed with the outside cell wall 3 of radiating groove.
In the utility model embodiment, the width of the radiating groove is incremented by from left to right.
In the utility model embodiment, each cooling fin will be divided into multiple case type structures in radiating groove, form sufficiently strong
The rigid support of degree, while heat dissipation area is also increased, it is conducive to the heat dissipation of rotor bearing.
