Description

A kind of collection wind flow guiding type electric motor end cap

Technical field

This utility model relates to a kind of motor component, and particularly collection wind flow guiding type electric motor end cap, belongs to technical field of motors.

Background technology

Application NEMA serial motors within the compressor have efficient, energy-conservation, noise is low, it is little to vibrate, lightweight, performance can The advantage such as lean on.Described motor must assure that in running relatively low bearing temperature could the most normally work, and extends electricity The service life of machine.The most traditional NEMA serial motors end cap as shown in Figure 6, electric motor end cap design time from the assembling of motor From the standpoint of energy, bearing chamber 5 is arranged on the center of end cover body 1, relies on end cover body single wall and the fixing support of inner side diagonal bar, whole Body structure is C-shaped.The electric motor end cap of this kind of structure is owing to bearing chamber is arranged on cover internal, little with extraneous contact area, at electricity After machine connects other equipment, it is nearly in closing space, when motor runs up, before the cooling wind of fan cannot arrive Position of bearings, it is difficult to the heat produced when dissipating generator operation in time, easily causes bearing temperature higher, shortens bearing and uses the longevity Life, affects motor performance.On the other hand, needing to install additional bearing end cover 7 when assembling, assembling process is loaded down with trivial details.Furthermore, this kind of structure The oiling drain path of electric motor end cap, all on bearing end cover, could can only thoroughly change grease under tearing machine state open, tool There is certain limitation.

Utility model content

The purpose of this utility model is the drawback for prior art, it is provided that a kind of beneficially cooling airflow leads to, thus Effectively reduce the collection wind flow guiding type electric motor end cap of bearing temperature.

Problem described in the utility model solves with following technical proposals:

A kind of collection wind flow guiding type electric motor end cap, including end cover body, is provided with bearing chamber, described end cap edge in the middle part of end cover body Axially it is sequentially provided with end cap outer wall and end cap inwall, connects through equally distributed connection post between end cap outer wall and end cap inwall, phase Adjacent connection constitutes cooling air channel between post, described bearing chamber is supported by end cap inwall.

Above-mentioned collection wind flow guiding type electric motor end cap, the gabarit of described end cap outer wall is that the circle being made up of arc-shaped edges and straight flange lacks Shape, arc-shaped edges position is the guide curve surface of inward wall direction arc-shaped bend.

Above-mentioned collection wind flow guiding type electric motor end cap, is uniformly arranged several radiating ribs between described end cover body and bearing chamber, end Several outer radiating ribs it are uniformly arranged between lid main body and end cap outer wall.

Above-mentioned collection wind flow guiding type electric motor end cap, described end cap outer wall is provided with bearing end cover, and end cap outer wall with bearing end cover is Integrative-structure.

Above-mentioned collection wind flow guiding type electric motor end cap, described cincture bearing end cover is provided with bearing oil groove, and the fluid of bearing oil groove can Enter through main body oil input channel, discharged by outer wall draining road.

For existing electric motor end cap, this utility model is unfavorable for that the problems such as heat radiation, assembling process is loaded down with trivial details are improved, its Advantage is embodied in following aspect: 1, end cap is double-walled construction, the gabarit design guide curve surface of end cap outer wall, utilizes wind to meet with obstruction The feature that can be refracted, utilizes the cooling wind assembled fully to dispel the heat by guide curve surface；2, arrange and a plurality of of extraneous contact dissipates Hot muscle, can distribute the heat inside bearing chamber, in the case of motor runs up, cools down motor fore bearing, Reduce bearing temperature, improve the good result of bearing life.3, end cap outer wall and bearing end cover are designed to integrative-structure, Processing and assembly work can be reduced.4, arranging bearing oil groove, the fluid of bearing oil groove can enter through main body oil input channel, by outward Wall draining road is discharged, and can be replaced by the lubricating oil in bearing chamber in the case of not tearing machine open.

Detailed description of the invention

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 5, this utility model includes end cover body 1, is provided with bearing chamber 5 in the middle part of end cover body. The edge of end cover body arranges four fixing lugs 2, is fixed on motor housing by 4, has enough comprcssive strength. Described end cap is double-walled construction, is sequentially provided with end cap outer wall 4 and end cap inwall 6 vertically.Bearing chamber is supported by end cap inwall.End Connect through equally distributed connection post 10 between cover outer wall and end cap inwall, at the cavity between end cap inwall and end cap outer wall, Cooling air channel is constituted between adjacent connection post.End cap outer wall is provided with bearing end cover 7, and end cap outer wall and bearing end cover are integrated knot Structure, can well ensure that the axiality requirement of bearing end cover and bearing chamber, saves dress simultaneously under a cutter adding man-hour During allotment of labor.It is uniformly arranged several radiating ribs 3 between end cover body and bearing chamber, is uniformly arranged between end cover body and end cap outer wall Several outer radiating ribs 9.On the one hand radiating ribs has one and strengthens supporting role bearing chamber, reduces vibrations, the most all right Play thermolysis.Outer radiating ribs is while playing booster action to end cover body, it is also possible to play thermolysis.

Referring to Fig. 1, Fig. 2, Fig. 4, from the point of view of assembling structure, the gabarit of end cap outer wall is by arc-shaped edges and straight flange structure The circle become lacks shape, and arc-shaped edges position is guide curve surface 4-1 of inward wall direction arc-shaped bend.Guide curve surface extends out to outer dissipating Outside hot muscle.Wind path is assembled and guides by the effect of guide curve surface, makes wind path cold to bearing chamber conveying along guide curve surface But wind, and flow in cooling air channel, thus the heat of bearing chamber is distributed.

Referring to Fig. 2, Fig. 4, being provided with bearing oil groove 8 around bearing end cover, the fluid of bearing oil groove can be by being arranged on end cap The main body oil input channel 12 of main body enters, and discharges by being arranged on the outer wall draining road 11 of end cap outer wall.Said structure is not tearing machine open In the case of substantially lubricating oil all of in bearing chamber can be replaced.
