Abstract
The utility model relates to a bearing sealing structure of a water-proofing motor; two angular contact bearings are arranged in parallel along the backward direction in an end cover, a motor shaft is arranged in an inner ring of a bearing, a bearing inner cap is arranged in the end cover for locating the bearing, a bearing outer cap is arranged on the end cover and is used for fixing a bearing outer ring; the bearing sealing structure is characterized in that: a protective cover is arranged outside the inner ring of the bearing on the motor shaft and is adjusted and fixed by a round nut, a rotating disc is arranged at the end of the motor shaft, a curved clearance is formed between the rotating disc and the bearing outer cap to form multiple labyrinth seal, and an oil seal is arranged between the motor shaft and the bearing outer cap. An O-shaped sealing ring is arranged on the contact surface of the bearing outer cap and the end cover. Cooling liquid which is splashed outwards under the action of centrifugal force of the rotating disc is sprayed at the outer end of the motor shaft when the bearing sealing structure works. The curved clearance is formed between the rotating disc and the bearing outer cap to form the multiple labyrinth seal, the bearing has double protection of the protective cover and the oil seal, so as to effectively prevent water mist from being intruded in the bearing outer cap.
Description
Technical field
The utility model relates to a kind of water proof machine bearing seal structure, to realize the effective protection of grinding machine with the grinding wheel spindle motor bearings, can effectively prevent in the water smoke intrusion bearing end cover.
Background technology
Grinding machine is with having cooling fluid in the grinding wheel spindle machine operation environment, the infringement of grinding refuse, and how to protect motor bearings is insoluble problem always.Thereby the exploitation of protecting reliable water proof machine bearing arrangement is very urgent.Conventional motor bearings safeguard structure is simple, and water can enter bearing along bearing end cover, can not reach protection effect.
The purpose of this utility model is to overcome above-mentioned weak point, thereby providing a kind of can effectively protect cooling fluid, the grinding refuse is invaded in the bearing, can effectively prevent in the water smoke intrusion bearing end cover service-strong water proof machine bearing seal structure.
The technical scheme that provides according to the utility model, a kind of water proof machine bearing seal comprises end cap, internal bearing cover, bearing, bearing end cover, motor shaft, two angular contact bearings are installed dorsad side by side in end cap, motor shaft is installed in the interior ring of bearing, internal bearing cover is installed in location bearing in the end cap, bearing end cover is installed on the end cap and the rigid bearing outer shroud, feature is: protective cover is installed outside the ring in the motor shaft upper bearing (metal), and fixing with the round nut adjusting, in the motor shaft termination rotating disk is installed, the shaped form gap is arranged between rotating disk and the bearing end cover, form multiple labyrinth seal, between motor shaft and the bearing end cover oil sealing is installed.
On the described bearing end cover with on the contact-making surface of end cap ○Xing Mifengquan is installed.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure.When the motor shaft outer end was sprayed with cooling fluid during work, cooling fluid was outwards splashed under the rotating disk centrifugal action.The shaped form gap is arranged between rotating disk and the bearing end cover, form multiple labyrinth seal, bearing has protective cover, and duplicate protections such as oil sealing can effectively prevent in the water smoke intrusion bearing end cover, to realize the effective protection of grinding machine with the grinding wheel spindle motor bearings.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise end cap 1, internal bearing cover 2, bearing 3, protective cover 4, round nut 5, bearing end cover 6, oil sealing 7, rotating disk 8, ○Xing Mifengquan 9, motor shaft 10 etc.
The utility model adopts at end cap 1 interior two angular contact bearings 3 and installs side by side dorsad, motor shaft 10 is installed in the interior ring of bearing 3, internal bearing cover 2 is installed in location bearing 3 in the end cap 1, bearing end cover 6 is installed on the end cap 1 and rigid bearing 3 outer shrouds, protective cover 4 is installed outside the ring in motor shaft 10 upper bearing (metal)s 3, and regulate the bearing working gaps with round nut 5, rotating disk 8 is installed in motor shaft 10 terminations, between rotating disk 8 and the bearing end cover 6 the shaped form gap is arranged, form multiple labyrinth seal, oil sealing 7 is installed between motor shaft and the bearing end cover 6.On the described bearing end cover 6 with on the contact-making surface of end cap 1 ○Xing Mifengquan 9 is installed,
The utility model bearing is by protection before and after internal bearing cover, the protective cover.When the motor shaft outer end was sprayed with cooling fluid during work, cooling fluid was outwards splashed under the rotating disk centrifugal action.The shaped form gap is arranged between rotating disk and the bearing end cover, form multiple labyrinth seal, can effectively prevent in the water smoke intrusion bearing end cover.In addition, between motor shaft and the bearing end cover oil sealing is housed.Bearing end cover and end cap contact-making surface are equipped with ○Xing Mifengquan.
