Abstract
The utility model discloses a bearing box which is used for ensuring that a main shaft is regularly used under a poor working environment containing water, sediment and dirt and is convenient for maintenance and manufacture. The bearing box comprises the main shaft, a spacer sleeve and a bearing shell, wherein an end sealing plate is arranged at the back end of the bearing shell; a sealing shell is further arranged on the main shaft at the front end of the bearing shell; the sealing shell and the bearing shell are detachably, fixedly and hermetically connected; a front part between the sealing shell and the main shaft is provided with a stuffing box, and a sealing filler is arranged in the stuffing box; and multiple groups of framework oil seals are arranged at a back part between the sealing shell and the main shaft. The bearing box disclosed by the utility model can be used for realizing that the dynamic sealing and static sealing of the bearing box prevent water and sediment from intruding the bearing box and prevent lubricating oil in the bearing box from leaking outward, so as to ensure the high-efficiency operation of a whole machine; and simultaneously, through utilizing the structured design, the sealing shell is not influenced when the bearing shell is maintained, the bearing shell is not influenced when the sealing shell on the front part is maintained, and the manufacturing and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of bearing housing, particularly a kind ofly is used for the bearing housing that under the abominable working environment of water, silt and the dirt normal use of assurance main shaft is convenient to safeguard manufacturing simultaneously.
Background technique
Existing sealed bearing case; Mainly being to be employed between bearing housing housing and the main shaft to adopt labyrinth seal, such as being exactly to adopt labyrinth seal in the patent 201020527331.8, is exactly between axle and housing specifically; Have the concavo-convex ring packing tooth combination of several little play that are arranged in order; Finally reach the stuffing box bearing case, the lubricant in the bearing housing does not spill, but this bearing housing can not satisfy job requirement under the mal-conditions such as muddy water, many ashes.
And for example patent 2010020125408.9 only adopts the outside framework oil seal mode to reach the order that the protection bearing housing is not invaded by muddy water, sandy soil between case shell and axle sleeve.But in reality, its effect is not fine, and especially under many rugged environments, such as washing environment such as sand, a large amount of dusts, its simple a kind of sealing means does not reach good airproof performance, safe and reliable, requirement that the life-span is long.Simultaneously, because sealing station is in the same place with the position of bearings, it safeguards and makes relative complex that system is not compact.
The model utility content
The purpose of the utility model is to provide a kind of bearing housing that adopts double seal and system architectureization, can overcome the deficiency of existing bearing housing.
To achieve these goals, the technological scheme of the utility model employing is: a kind of bearing housing of sealed type comprises main shaft; Spacer, cartridge housing, the rear end of cartridge housing is provided with end-plate; Collar bush is located in the chamber of cartridge housing and end-plate formation in spacer and with spacer jointly; Cartridge housing is detachable fixed seal connection with the end capping, on the main shaft of cartridge housing front end, also is provided with capsul, and capsul and cartridge housing are detachable fixed seal connections; The capsul front end is provided with sealing gland, and said sealing gland and capsul are detachable fixed seal connections; Front portion between capsul and main shaft is provided with stuffing box, is provided with stuffing box packing in the said stuffing box; The rear portion is provided with many group outside framework oil seals between capsul and main shaft.
Further be, said stuffing box packing is the oil immersion asbestos packing, in needing the environment of high pressure, can adopt the high pressure asbestos packing.
Further be between said cartridge housing and the end-plate, between capsul and the cartridge housing, and detachable being sealedly and fixedly connected between end cover and the capsul, all to be to adopt bolt to connect and with asbestos cardboard and be coated with sealer and seal.
Further, in order to make bearing housing better sealing is arranged, said outside framework oil seal is provided with 10 groups at least,
The beneficial effect that above technological scheme reached is: owing to be provided with capsul at the cartridge housing front end, in capsul, be provided with packing seal and outside framework oil seal double seal mode, the sealing stroke is longer; Adopt detachable fixed seal connection between the housing, bearing housing not only can effectively reach the muddy water, the dust that stop the external world and get into casing when guaranteeing the main shaft operation like this; Lubriciousization in the case can not leak yet; Also, can not influence the rear end bearing shell when safeguarding capsul because the housing structure design does not influence capsul when safeguarding the rear-end of spindle cartridge housing; Filler, outside framework oil seal repair and replacement are convenient, make corresponding part and also become and be easy to.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Number among the figure: 1 main shaft, 2 outside framework oil seals, 3 capsuls, 4 bolts, 5 cartridge housings, 6 stuffing boxes, 7 sealing glands, 8 end-plates, 9 asbestos cardboards, 10 spacers.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Double seal formula structuring bearing housing as shown in Figure 1 comprises main shaft 1, spacer 10, and cartridge housing 5 adopts bolt to be connected with end capping 8, and with asbestos cardboard and be coated with sealer and seal; In the chamber that cartridge housing 5 and end-plate 8 constitute, cone bearing and selfaligning bearing support the main shaft 1 that is enclosed within the spacer, and main shaft 1 rear end is provided with by the fixing lock washer of king-bolt; On the main shaft 1 of cartridge housing 5 front ends, be glued with capsul 3; Capsul 3 adopts bolt to be connected with cartridge housing 5; And with asbestos cardboard and be coated with sealer and seal; Capsul 3 front ends carry out capping with sealing gland 7, and sealing gland 7 and capsul 3 adopts bolt to be connected, and with asbestos cardboard and be coated with sealer and seal; There is stuffing box 6 front portion between capsul 3 and main shaft 1, in be filled with the oil immersion asbestos packing, the sealing stroke of stuffing box 6 is provided with 10 groups of outside framework oil seals for the 35mm rear portion, its sealing stroke be 116mm.
Above-mentioned bearing housing when bearing is adjusted or keeped in repair, as long as open end-plate 8, can be adjusted or keep in repair, as add lubricant the parts in the cartridge housing.As hermetic unit is carried out repair and replacement, just can realize its purpose easily as long as open anterior capsul.This bearing housing can satisfy normal long lifetime work under rugged environment in a word, and is convenient to maintenance process.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have change and change.All within the spirit and principle of the utility model, any modification of being done, improvement etc. all should be included within the protection domain of the utility model.
