Abstract

This utility model flat spring ears anchor ear dust bearing; it is made up of bearing block, bolt, leaf spring, U-shaped liner, ears anchor ear and rapping shaft; it is characterized in that: the top of bearing block is provided with installing hole; leaf spring is arranged in bearing block; U-shaped liner sets off the inner side at leaf spring; after installing ears anchor ear according to the spacing set on rapping shaft, being placed directly on U-shaped liner, rapping shaft slowly rotates on U-shaped liner.This utility model, compared with prior art, has following obvious advantage and good effect: 1. compared with conventional support roller formula roller bearing, and simple in construction, metalworking amount significantly reduces, and the only internal diameter two ends of ears anchor ear need metalworking, and production cost is relatively low.2. the ears anchor ear on rapping shaft can be made to be in contact condition all the time with U-shaped liner due to the elastic reaction of leaf spring when rotating, rapping shaft is relatively more steady real, and ramping effect is good.

Description

Flat spring ears anchor ear dust bearing

Technical field

This utility model relates to a kind of bearing, particularly relates in a kind of flat spring ears anchor ear dirt on electric cleaner Bearing.

Background technology

Dust bearing is cathode of electric dust collector rapping and the vitals of anode rapping, due to dust bearing all the year round at dust Middle operating, although rotating speed only has per minute 0.5 to turn left the right side, but owing to dust plays the effect of abrasive sand, still can wear and tear Phenomenon, thus the quality of dust bearing structure and quality directly influences the properly functioning of equipment.The type of dust bearing application More, current common application mainly have support roller roller bearing and whole slide formula two class, but currently the majority electric precipitation Device producer uses support roller roller bearing, and owing to being rolling friction between rotary shaft and bearing, service life is longer, but Its support roller, torr rod etc. are required for metalworking and heat treatment, and cost is higher.Its another shortcoming is due to rapping shaft length Length, concentricity are poor, are in discontinuous connection state between it and bearing, and rapping shaft is that floating type is placed on two rollers, surely Reality is poor, may make some difference ramping effect.

Whole slide formula dust bearing simple in construction, employing is integrally cast, install, overhaul, use more convenient, raw Product cost is relatively low.But common monolithic devices dust bearing is owing between axle and bearing being direct sliding friction state, and it Gap between is less and rapping shaft length is longer, and concentricity is the most poor, there is strong scraping phenomenon, adds grinding of dust Mill, rotary shaft and bearing all can occur more serious abrasion, not have the accessory that axle sleeve etc. can be changed between the two, can cause rapping Axle directly weares and teares, and causes service life shorter.This dust bearing due between rotary shaft with bearing contact all the time than Tightr, it is possible to reach the relatively more steady real state of rapping shaft, so that the ramping effect of beater is relatively good.

The dust bearing that several cost of market demand is relatively low, ramping effect good, the life-span is grown again.

Utility model content

This utility model, is achieved through the following technical solutions:

This utility model, is made up of bearing block, bolt, leaf spring, U-shaped liner, ears anchor ear and rapping shaft, its Being characterised by: the top of bearing block is provided with installing hole, leaf spring is arranged in bearing block, and U-shaped liner sets off at leaf spring Inner side, on rapping shaft according to set spacing install ears anchor ear after, be placed directly on U-shaped liner, rapping shaft is slowly U-shaped liner rotates.

As preferably, described bearing block selects plain cast iron casting, with the bearing block in conventional support roller formula dust bearing General, during maintenance, because the position that bearing block does not wear and tear, can reuse.

As preferably, leaf spring uses steel spring plate punching, bends shaping, and the width of steel spring plate is fitted mutually with bearing block Join.

As preferably, U-shaped liner uses the preferable medium carbon steel of anti-wear performance to make, and adopts between U-shaped liner and leaf spring Fix with screw and spring washer.

As preferably, described ears anchor ear selects wear resistant cast iron casting, and the width of ears anchor ear is suitable with leaf spring, Two pieces of each semicirculars in shape, four angles set mounting ear, and the internal diameter two ends of ears anchor ear need lathe process, by bolt, nut and Spring washer is held tightly on rapping shaft.

During assembling, bolt is through the Kong Houyong nut screwing clamping on the hole and leaf spring of bearing block.

Rapping shaft is placed directly on U-shaped liner after installing ears anchor ear, and the velocity of rotation of rapping shaft slowly, but is shaken Spooling length is the longest, and concentricity is poor, due to the elastic reaction of leaf spring during rotation, can make ears anchor ear on rapping shaft with U-shaped liner is in contact condition all the time, and rapping shaft is relatively more steady real, is conducive to improving ramping effect.

This utility model, compared with prior art, has following obvious advantage and a good effect:

1., compared with conventional support roller formula roller bearing, simple in construction, metalworking amount significantly reduces, only ears anchor ear Internal diameter two ends need metalworking, production cost is relatively low.

2. when rotating, the ears anchor ear on rapping shaft can be made to be in all the time with U-shaped liner due to the elastic reaction of leaf spring Contact condition, rapping shaft is relatively more steady real, and ramping effect is good.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings and this utility model is described in further detail by detailed description of the invention:

As it is shown in figure 1, this utility model, by bearing block 1, bolt 2, leaf spring 3, U-shaped liner 4, ears anchor ear 5 Form with rapping shaft 6, it is characterised in that: the top of bearing block 1 is provided with installing hole, and leaf spring 3 is arranged in bearing block 1, U-shaped Liner 4 sets off the inner side at leaf spring 3, after rapping shaft 6 installs ears anchor ear 5 according to the spacing set, is placed directly in U-shaped On liner 4, rapping shaft 1 slowly rotates on U-shaped liner 4.

As preferably, described bearing block 1 selects plain cast iron to cast, with the bearing block in conventional support roller formula dust bearing General, during maintenance, because bearing block 1 does not has the position of abrasion, can reuse.

As preferably, leaf spring 3 uses steel spring plate punching, bends shaping, the width of steel spring plate 3 and bearing block 1 Suitable.

As preferably, U-shaped liner 4 uses the preferable medium carbon steel of anti-wear performance to make, between U-shaped liner 4 and leaf spring 3 Screw 31 and spring washer 32 is used to fix.

As preferably, described ears anchor ear 5 selects wear resistant cast iron to cast, and the width of ears anchor ear 5 is fitted with leaf spring 3 phase Joining, two pieces of each semicirculars in shape, four angles set mounting ear, and the internal diameter two ends of ears anchor ear 5 need lathe process, by bolt 51, Nut 52 and spring washer 53 are held tightly on rapping shaft 6.

During assembling, bolt 21 is tightened through the Kong Houyong nut 22 on the hole and leaf spring 3 of bearing block 1.

Rapping shaft 6 is placed directly in after installing ears anchor ear 5 on U-shaped liner 4, and the velocity of rotation of rapping shaft 6 slowly, can The length being rapping shaft 6 is the longest, and concentricity is poor, due to the elastic reaction of leaf spring 3 during rotation, can make on rapping shaft 6 Ears anchor ear 5 and U-shaped liner 4 are in contact condition all the time, and rapping shaft 6 is the most steady real, is conducive to improving ramping effect.
