Abstract
The utility model discloses a kind of elastic cylinder rolling bearing, by rapping shaft, on split axle housing, under split axle housing, circular roller, circular roller restraint strap, elastic support, clamping bolt, bearing support and construction bolt and form, it is characterized in that: circular roller is by the constraint of circular roller restraint strap, being arranged on two splits between axle housing and rapping shaft, when rapping shaft slowly rotates, circular roller slowly rolls at the inner chamber that two are split axle housing.This rolling bearing rapping shaft is relatively more steady real, and ramping effect is good; And obviously extend the working life of dust bearing and rapping shaft.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of elastic cylinder rolling bearing on electric cleaner.
Background technique
Dust bearing is the vitals of cathode of electric dust collector rapping and anode rapping, because dust bearing operates all the year round in dust, although rotating speed only has 1 turn or slower per minute, because dust plays the effect of abrasive sand, still wear phenomenon can occur.The type of dust bearing application is more, current common application mainly contain support roller rolling type bearing and whole slide formula two class, what present most of electric cleaner producer adopted is support roller rolling type bearing, owing to being rolling friction between rotatingshaft and bearing, working life is longer, but its support roller, holder rod etc. all need gold machining and heat treatment, and cost is higher.Its another shortcoming rapping shaft is that floating type is placed on two rollers, steady not real, may have impact to ramping effect.
Whole slide formula dust bearing structure is simple, and adopt cast inblock to form, cost of production is lower.But common integral type dust bearing is owing to being direct sliding friction state between axle and bearing, and gap between them is less and the concentricity of rapping shaft is poor, there is strong scraping phenomenon, causes working life shorter.This dust bearing compares closely all the time due to the contact between rotatingshaft with bearing, can reach the relatively more steady real state of rapping shaft, thus make the ramping effect of beater relatively good.
The dust bearing that several cost of market demand is lower, ramping effect good, the life-span is grown again.
Model utility content
The utility model is achieved through the following technical solutions:
The utility model elastic cylinder rolling bearing by rapping shaft, on split axle housing, under split axle housing, circular roller, circular roller restraint strap, elastic support, clamping bolt, bearing support and construction bolt and form, it is characterized in that: circular roller is by the constraint of circular roller restraint strap, being arranged on two splits between axle housing and rapping shaft, when rapping shaft slowly rotates, circular roller slowly rolls at the inner chamber that two are split axle housing.
As preferably, split on described axle housing and under split axle housing and select wear resisting cast iron cast, two split axle housing combine after diameter of bore and rapping shaft suitable, their inner chamber and circular roller-contact place adopt machined into, similar to common axle housing.
As preferably, the bottom of splitting axle housing under described is provided with leakage ash-pit.
As preferably, described circular roller adopts cold-drawn round steel manufacture, and cut off rear two ends rounding, material can be identical with rapping shaft.
As preferably, described circular roller restraint strap adopts iron sheet to make, and circular roller can be constrained in relatively-stationary position and roll.
As preferably, described elastic support adopts Spring Steel Wire to bend to required shape.
As preferably, adopt clamping bolt on split axle housing, under split axle housing and elastic support is fixed together, split axle housing built with circular roller and circular roller restraint strap, they constitute the main body of elastic cylinder rolling bearing.
As preferably, above split axle housing, under split after axle housing and elastic support are fixed together and be installed on bearing support by construction bolt again.
As preferably, during in-site installation first circular roller and circular roller restraint strap composition sleeve integrating on rapping shaft, adopt when moving to bearing support position clamping bolt on split axle housing, under split after axle housing and elastic support are fixed together and be installed on bearing support by construction bolt again.
The utility model compared with prior art, has following obvious advantage and good effect:
1., compared with support roller rolling type bearing, because the elastic reaction of elastic support can make rapping shaft, circular roller and split axle housing to be in contact condition all the time when elastic cylinder rolling bearing rotates, rapping shaft is relatively more steady real, and ramping effect is good.
2. compared with whole slide formula dust bearing, rapping shaft and the circular roller of elastic cylinder rolling bearing and to split between axle housing be all rolling friction, more much smaller than the wear extent of sliding friction, obviously extend the working life of dust bearing and rapping shaft.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
As shown in Figure 1, the utility model elastic cylinder rolling bearing by rapping shaft 1, on split axle housing 2, under split axle housing 3, circular roller 4, circular roller restraint strap 5, elastic support 6, clamping bolt 7, bearing support 8 and construction bolt 9 and form, it is characterized in that: circular roller 4 is by the constraint of circular roller restraint strap 5, being arranged on two splits between axle housing 2,3 and rapping shaft 1, when rapping shaft 1 slowly rotates, circular roller 4 slowly rolls at the inner chamber that two are split axle housing 2,3.
As preferably, split on described axle housing 2 and under split axle housing 3 and select wear resisting cast iron cast, two split the diameter of bore after axle housing 2,3 combination and rapping shaft 1 suitable, their inner chamber and circular roller 4 contacting point adopt machined into, similar to common axle housing.
As preferably, the bottom of splitting axle housing 3 under described is provided with Lou ash-pit 31.
As preferably, described circular roller 4 adopts cold-drawn round steel manufacture, cuts off rear two ends rounding, and material can be identical with rapping shaft 1.
As preferably, described circular roller restraint strap 5 adopts iron sheet to make, and circular roller 4 can be constrained in relatively-stationary position and roll.
As preferably, described elastic support 6 adopts Spring Steel Wire to bend to required shape.
As preferably, adopt clamping bolt 7 on split axle housing 2, under split axle housing 3 and elastic support 6 is fixed together, split axle housing 2,3 built with circular roller 4 and circular roller restraint strap 5, they constitute the main body of elastic cylinder rolling bearing.
As preferably, above split axle housing 2, under split after axle housing 3 and elastic support 6 are fixed together and be installed on bearing support 8 by construction bolt 9 again.
As preferably, first circular roller 4 and circular roller restraint strap 5 are formed sleeve integrating on rapping shaft 1 during in-site installation, adopt when moving on to the position of bearing support 8 clamping bolt 7 on split axle housing 2, under split after axle housing 3 and elastic support 6 are fixed together and be installed on bearing support 8 by construction bolt 9 again.
