Abstract
A novel bearing sleeve is used for vertical blow down pumps. A convex table is arranged under the flange of the bearing sleeve. The convex table is combined with the sinking slot on the pan against reverse turning to form a labyrinth seal. The sealing method used is safe and reliable, not regularly exchanging the felt oil seal, causing the wear of the parts and making the water entering into the bearing chamber. In addition, a screw hole is added at the upper end surface of the bearing sleeve and a groove is added at the lower part. The screw hole can make the end cover against reverse turning link with the bearing sleeve through the bolts. The groove is used to install the retaining ring and can make resistance force through the retaining ring transfer to the bearing group including a deep groove ball bearing, a bearing spacer ring and an angle contact ball bearing installed in pair, ensuring the normal use of the water pump.
Description
Technical field
The utility model relates to a kind of bearing housing structure that is used for vertical sewage pump, particularly to the improvement of bearing housing structure.
Background technique
Vertical sewage pump is easy to form counter-rotating when starting, so the counter-rotating will prevent starting mode of pump with anti-reverse mechanism the time.Bearing housing is a component part of anti-reverse mechanism.Bearing in the anti-reverse mechanism will adopt lubricant oil or lubricating grease to lubricate, so bearing bore will seal, prevents into water.Be processing one groove on the counnter attack rotating disk in original structure, dress felt collar oil sealing seals in groove, because water pump can wearing and tearing between felt collar oil sealing and part when rotating, thereby cause seal failure, cause intaking in the bearing bore, cause the damage of bearing, influenced the normal use of water pump.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above in the prior art, and a kind of novel improved bearing housing is provided.Of the present utility model being characterised in that a: boss is set below flange of sleeve of bearing, makes its formation labyrinth seal that matches with deep gouge on the counnter attack rotating disk, thereby reach the purpose of sealing.Be provided with a tapped hole in the upper-end surface of bearing housing in addition, be provided with in the bottom one groove, be used with other part and make whole anti-reverse mechanism have the ability of resisting dynamical reaction.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is the prior art structural representation;
Accompanying drawing 2 is the utility model structural representation;
Accompanying drawing 3 is the utility model application principle figure.
Adjust nut, 3 screws, 4 anti-reverse end caps, 5 straight pins, 6 counnter attack rotating disks, 7 bearing supports, the angular contact ball bearing of 8 paired mounting, 9 back-up rings, 10 bearing housings, 11 deep groove ball bearings, 12 bearing spacer rings, 13 labyrinth seals, 14 bearing bores, 15 fitting surfaces, 16 tapped holes, 17 boss, 18 grooves for 1,2.
Embodiment
Processing one boss 17 cooperates with a deep gouge of counnter attack rotating disk 6 upper-end surfaces below flange of sleeve of bearing, the deep gouge of the boss of bearing housing and counnter attack rotating disk is 1 millimeter in the gap of vertical direction, gap in the horizontal direction is 0.5 millimeter (see figure 3), and labyrinth seal is formed under high speed rotating by substantially horizontal three places 0.5 mm clearance.Adopt this sealing means safe and reliable, need not regularly replace the felt collar oil sealing, can not cause the wearing and tearing of part.Make in the bearing bore and can not intake, thereby guaranteed the normal use of water pump.
Increased tapped hole in the upper-end surface of bearing housing in addition, increased groove in the bottom, tapped hole can make anti-reverse end cap 4 link together by screw 3 with bearing housing, groove is used for installing back-up ring 9, can make dynamical reaction pass to bearing pack (angular contact ball bearing 8 that comprises deep groove ball bearing 11, bearing spacer ring 12 and paired mounting) by back-up ring 9.Detailed process is as follows: when water pump is subjected to upwards dynamical reaction, dynamical reaction is passed to by screw thread by axle 1 and is adjusted nut 2, because adjusting nut all is to be connected by screw with anti-reverse end cap, anti-reverse end cap with bearing housing, dynamical reaction has just been passed to bearing housing like this, bearing housing is passed to bearing pack by back-up ring with dynamical reaction, bearing pack is passed to the counnter attack rotating disk with dynamical reaction, because the counnter attack rotating disk is connected with screw with bearing support, and bearing support is fixed on the ground, dynamical reaction has just been passed to ground like this, water pump just can not be lifted, thereby has guaranteed the normal use of water pump.When water pump will reverse, straight pin 5 can fall in the groove on the counnter attack rotating disk 6, blocked the rotation of anti-reverse end cap by straight pin, and anti-reverse end cap and axle be by the key transmission, spool also stopped operating like this, thereby had stoped the counter-rotating of water pump.
Claims (2)
1, a kind of novel bearing cover that is used for vertical sewage pump is characterized in that, a boss is set below flange of sleeve of bearing, makes its formation labyrinth seal that matches with deep gouge on the counnter attack rotating disk.
2, according to the described a kind of novel bearing cover that is used for vertical sewage pump of claim 1, it is characterized in that, one tapped hole is set, a groove is set in the bottom in the upper-end surface of bearing housing.
