Abstract
The utility model relates to a structure of an intermediate bearing box used for a submerged sewage pump, which comprises a box body. The structure of the intermediate bearing box used for the submerged sewage pump is characterized in that the box body is a cylindrical structure; spigots are arranged on outer lateral sides of the middle portion of the box body, disassembling screwed holes which are through holes are arranged on the spigots, a retaining ring groove and oil baffle plate grooves are arranged on inner side of an upper end of the box body, bearing chambers and seal grooves are arranged in the middle portion of the box body, the disassembling screwed holes communicated with the bearing chambers are arranged on matching surfaces of outer rings of bearings of the intermediate bearing box. The structure of the intermediate bearing box used for the submerged sewage pump brings more convenience to dissembling of the bearings and capable of protecting the bearings.
Description
Technical field
The utility model relates to a kind of intermediate bearing box structure that is used for liquid down blow pump.
Background technique
Liquid down blow pump belongs to the major axis pump; It is a multi-section type, all will adorn a bearing on every section axle, is directly to be contained in the link press span at the existing structure middle (center) bearing; Very inconvenient when dismounting; Particularly when bearing is a lot, has torn a pump open and need expend for a long time, and be easy to damage of bearings.Therefore demand improving the Bearing Installation structure of liquid down blow pump in the existing technology urgently, to solve the long problem that expends time in that runs into when removing and installing at present.
Summary of the invention
The purpose of the utility model is that the Bearing Installation that solves liquid down blow pump in the existing technology is constructed existing the problems referred to above, and a kind of intermediate bearing box structure that is used for liquid down blow pump is provided.A kind of intermediate bearing box that is used for liquid down blow pump of the utility model design comprises box body, and it is characterized in that: box body is a cylindrical structural; The middle part outer side surface is provided with seam, on seam, is offering the dismounting tapped hole, and this tapped hole is a through hole; Offer circlip groove and oil baffle groove in inboard, box body upper end; Middle part in the box body is bearing bore and seal groove, offers the bearing removal tapped hole on the bearing outer ring fitting surface of intermediate bearing box, and the bearing removal tapped hole communicates with bearing bore.The utility model has the advantages that can make the dismounting bearing convenient, can also protect bearing.
Description of drawings
Below in conjunction with accompanying drawing and instance the utility model is elaborated.
Accompanying drawing 1 is the structural representation of the utility model; Accompanying drawing 2 is the use principle figure of the utility model.
Embodiment
The intermediate bearing box is a cylindrical structural; The centre is processed with seam, is processed with the dismounting tapped hole on the fitting surface of seam, and this tapped hole is a through hole; Offer circlip groove and oil baffle groove in inboard, box body upper end; Middle part in the box body is bearing bore and seal groove, offers the bearing removal tapped hole on the bearing outer ring fitting surface of intermediate bearing box, and the bearing removal tapped hole communicates with bearing bore.Bearing 12 is housed in the bearing bore of intermediate bearing box; Oil baffle 16 is housed in the oil baffle groove; The effect of oil baffle is to prevent that the lubricating grease in the bearing is thrown out of, and circlip for hole 17 is housed in the circlip groove, and its effect is the fixed stop oiled-plate method; A shape seal ring 18 is housed in the seal groove, and its effect is to prevent that the lubricating grease in the bearing from leaking between intermediate bearing box and axle downwards.The intermediate bearing box cooperates through seam with upper and lower link press span, and is clipped in the middle of two link press spans 13, and two link press spans are fixing through screw bolt and nut 14, between two link press spans O-ring seals 15 are housed, and can prevent that liquid from getting in the link press span.During dismounting, the top link press span of at first dismantling screws in the dismounting tapped hole of intermediate bearing box with screw then; Make screw withstand down the fitting surface of link press span, so just can be with intermediate bearing box jack-up, and from dismantling the link press span down; This moment, bearing was positioned at the intermediate bearing box, was dismantled simultaneously.Dismantle respectively then circlip for hole and oil baffle, and then screw in the bearing removal tapped hole with the lower end surface of screw from the intermediate bearing box, the outer ring that makes screw withstand bearing ejects bearing in the intermediate bearing box.In whole unloading process, need not beat bearing, so not only make convenient disassembly, also protect bearing not dismounted badly.19 is axle among Fig. 2.
