Description
Technical field
The utility model relates to electric motor end cap field, specially a kind of electric motor end cap bearing chamber optimizes structure.
Background technique
Bearing is one of necessary component of most motors, and bearing is inevitable due to various reasons during operation to be generated
Vibration, so as to cause noise, in order to improve China's motor product in the competitiveness of international market, there is an urgent need to take necessary arrange
It applies control or reduces the vibration generated by bearing operation and noise, to effectively reduce vibration and the noise of motor entirety.
Existing electric motor end cap, bearing chamber interior walls embed equipped with several equidistant annular grooves and are cased with damping ring, subtract
Vibration ring a part is in annular groove, and a part is squeezed in bearing chamber by bearing.Due to being additionally arranged damping ring, can have
The vibration and the noise therefore generated that the reduction of effect generates due to bearing operation, to improve the overall performance of equipment.
Although the patent solves the above problem, but there is also some shortcomingss, and such as the damping ring of annular is when being packed into annular groove
It is easy out-of-flatness, some places are excessively protruded, and need to take time to adjust, and otherwise it is easy to cause installation bearing chamber inconvenient, and
Damping ring can be taken out of again when disassembly, next time is readjusted again.
For this purpose, we provide a kind of electric motor end cap bearing chambers to optimize structure.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of electric motor end cap bearing chamber optimization structure, solves
The inconvenient problem of bearing chamber dismounting equipped with damping ring at present.
To achieve the above object, the utility model provides the following technical solutions: a kind of electric motor end cap bearing chamber optimization structure,
Including electric motor end cap, bearing chamber is equipped in the electric motor end cap, bearing chamber interior walls are equipped at least one layer of damping layer, the damping layer
It is provided with four sections of arc grooves at equal intervals, arc shock absorption bar is equipped in every section of arc groove, and arc shock absorption bar width is less than arc groove width
Degree, the arc shock absorption bar back side are connected by the locating slot that connection strap is inserted into the arc groove back side, and the processing of connection strap side is with teeth；
The electric motor end cap surface is equipped with T-type locating rod, and T-type locating rod is inserted into arc groove, and T-type locating rod lower part
It is machined with the gear with connection strap cooperation, and gear bottom end is equipped with polygon limited block；The arc groove bottom be machined with it is more
The corresponding polygon limiting slot of side shape limited block.
Preferably, the bearing chamber interior walls are equipped with two layers of damping layer, and the polygon limiting slot is equipped with second layer damping layer
Arc groove bottom.
Preferably, the polygon limited block is square with polygon limiting slot.
Preferably, the arc shock absorption bar length is 1/8th circular arcs.
The utility model has the beneficial effects that installation bearing is convenient, is easy to adjust, when disassembly is also in this way, improving assembly
Efficiency.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the attachment structure schematic diagram of the shock absorption strip of the utility model.
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, 2, 3, a kind of electric motor end cap bearing chamber optimizes structure, including electric motor end cap 1, the electric motor end cap 1
Interior to be equipped with bearing chamber 2,2 inner wall of bearing chamber is equipped at least one layer of damping layer；The damping layer is provided with four sections of arc grooves 3 at equal intervals,
Arc shock absorption bar 4 is equipped in every section of arc groove 3, and 4 width of arc shock absorption bar is less than 3 width of arc groove, the arc shock absorption bar
Length is 1/8th circular arcs；4 back side of arc shock absorption bar is connected by the locating slot 6 that connection strap 5 is inserted into 3 back side of arc groove, and
The processing of 5 side of connection strap is with teeth；
1 surface of electric motor end cap is equipped with T-type locating rod 7, and T-type locating rod 7 is inserted into arc groove 3, and T-type locating rod
7 lower parts are machined with the gear 8 cooperated with connection strap 5, and 8 bottom end of gear is equipped with polygon limited block 9；3 bottom surface of arc groove
It is machined with polygon limiting slot 10 corresponding with polygon limited block 9.
The utility model is used to contact with bearing extruding using four sections of arc grooves 3 with arc shock absorption bar 4；Arc shock absorption bar 4
Passed in and out in locating slot 6 by connection strap 5, convenient for the installation of bearing with contact, equally reached vibration damping, noise reduction effect.Pass through T
The cooperation of the tooth of the gear 8 of type locating rod 7 and connection strap 5 realizes that the disengaging of arc shock absorption bar 4 controls, and when operation, polygon is avoided to limit
Position block 9 is inserted into polygon limiting slot 10, and rotation T-type locating rod 7 retracts arc shock absorption bar 4, has been subsequently mounted bearing, has rotated T
Type locating rod 7 squeezes arc shock absorption bar 4 and bearing, or adjusts the distance of the stretching of arc shock absorption bar 4, installs bearing and arc
Shape shock absorption bar 4 squeezes contact, then pushes down on T-type locating rod 7 and polygon limited block 9 is made to be inserted into polygon limiting slot 10,
It realizes limit, prevents T-type locating rod 7 from rotating, and then limit the position of arc shock absorption bar 4；Simultaneously because there is certain squeeze
Power after being transmitted to the gear 8 of T-type locating rod 7 from connection strap 5, so that polygon limited block 9 has certain torque, can prevent
Polygon limited block 9 skids off polygon limiting slot 10.The cooperation of T-type locating rod 7 and connection strap 5 can be understood as gear 8 and tooth
The cooperation of item.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modification, equivalent replacement or improvement etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
