Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to FIGS. 1-5:
the first embodiment is as follows:
a disc type low-power permanent magnet machine comprises a mounting frame plate 1 and a permanent magnet machine 2 mounted on the mounting frame plate, wherein a rotating shaft 3 is rotatably arranged in the permanent magnet machine 2, oil holes 44 are uniformly distributed in the outer portion of the rotating shaft 3, a winding disc 4 which is hollow in the inner portion and communicated with the oil holes 44 is sleeved outside the oil holes 44, an oil storage structure communicated with the winding disc 4 is mounted on the winding disc 4, the oil storage structure is fixed on the permanent magnet machine 2 through a fixing plate 45, firstly, lubricating oil is put into the oil storage structure, the rotating shaft 3 is driven to rotate when the permanent magnet machine 2 works, oil in the oil storage structure flows on the rotating shaft 3 through the oil holes 44 in the inner cavity of the winding disc 4 to play an effective lubricating and anti-blocking effect, and the normal work of the permanent magnet machine 2 is prevented from being affected due to blocking caused by the.
The cavity bottom of the hollow cavity in the winding disc 4 is provided with a through groove for communicating the rest of the oil holes 44, the height of the communication part of the through groove and the oil holes 44 is the lowest, so that the lubricating oil in the winding disc 4 directly flows into the oil holes 44 through the winding disc 4, and the flowing accuracy, timeliness and high efficiency of the lubricating oil are improved.
The oil storage structure comprises a drainage disc 42 communicated with an oil hole 44, the drainage disc 42 is connected with a storage device 41 communicated with the drainage disc 42, an upper cover 43 is arranged on the storage device 41, lubricating oil is stored in the storage device 41, enters the winding disc 4 along the storage device 41 and the drainage disc 42 under the action of gravity, and finally lubricates the whole rotating shaft 3 and components connected with the rotating shaft 3 through the oil hole 44.
The flow guiding disc 42 and the oil hole 44 are conical, and the diameter value of the opposite ends of the flow guiding disc 42 and the oil hole 44 is the minimum, so that the lubricating oil between the flow guiding disc 42 and the oil hole 44 is more efficiently butted and guided, and meanwhile, the lubricating oil is prevented from accidentally flowing out of the butted port.
The outside of pivot 3 is equipped with the hollow layer, and the oilhole 44 on the pivot 3 link up the hollow layer and extend to and become the notch form on the pivot 3, and at the in-process that lubricating oil leads to oilhole 44 through drainage dish 42, when the great and synchronous, instant transmission of lubricating oil volume to pivot 3 and the working part that meets with pivot 3, lubricating oil stores and accomodates in the hollow layer of pivot 3, simultaneously through making the inside big groove footpath of the outside little groove footpath of oilhole 44, can effectively prevent that pivot 3 pivoted in-process from driving lubricating oil and throw away, has further guaranteed the validity of this lubricated work of lubricating mechanism.
In the second embodiment, the difference between the present embodiment and the first embodiment is:
the plug plate 52 positioned in the inner cavity of the storage device 41 is arranged between the opposite surfaces of the upper cover 43 and the drainage disc 42, the plug plate 52 can be deformed and is externally connected with an outer connecting plate 51 embedded on the cavity wall of the storage device 41, the outer connecting plate 51 is pulled to drive the plug plate 52 to deform, so that the lubricating oil in the storage device 41 is limited in quantity and is led into the winding disc 4 through the drainage disc 42, the quantity of the guided lubricating oil is controllable, and meanwhile, the practicability of the assembly is further improved.
The working principle is as follows:
firstly, lubricating oil is put into the storage device 41, the permanent magnet machine 2 drives the rotating shaft 3 to rotate when in operation, oil in the oil storage structure enters the winding disc 4 along the storage device 41 and the drainage disc 42 under the action of gravity, and finally the whole rotating shaft 3 and components connected with the rotating shaft 3 are lubricated through the oil hole 44.
In the process that lubricating oil leads to the oilhole 44 through drainage dish 42, when the lubricating oil volume is great and can not synchronous, instant transmission to pivot 3 and the working part that meets with pivot 3, lubricating oil stores and accomodates in the hollow layer of pivot 3, through making the inside big channel diameter of the outside little channel diameter of oilhole 44, can prevent effectively that pivot 3 pivoted in-process from driving lubricating oil and throw away.
When the lubricating oil is led out, the outer connecting plate 51 is pulled to drive the blocking plate 52 to deform, so that the limited amount of the lubricating oil in the storage 41 is led into the winding disc 4 through the drainage disc 42, and the led-out amount of the lubricating oil is controlled.
Although embodiments of the present invention have been shown and described in the description of the present invention, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
