Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of bearing bush abrasion monitor of the present utility model.
Embodiment
The embodiment of bearing bush abrasion monitor of the present utility model: as shown in Figure 1, comprise monitoring support and along the vertical direction positioning and guiding turn and be assigned in the bearing bracket of monitoring on support, bearing bracket is connected by the offset axis 5 vertically extending and offset axis 5 upper ends, horizontally extending stationary shaft 9 forms, on stationary shaft 9, turning set is provided with rolling body, and rolling body adopts the roller 7 of nylon material; On stationary shaft 9, be positioned at roller both sides and be also arranged with respectively spacing catch 6, offset axis 5, stationary shaft 9 and spacing catch 6 are stainless steel material.Spacing catch 6 is undertaken spacingly by being radially installed on locking pin 8 pair rollers 7 on stationary shaft 9, and while being applied on rotary drum vacuum filter, roller 7 contacts with the bottom roll extrusion of rotating the axle of assembling in filter bearing shell to be measured.Monitoring support comprises the housing 11 of lower ending opening, and housing lower ending opening place is installed with gland 12 by screw, and the offset axis 6 of bearing bracket is vertically through housing inner chamber, in the present embodiment, guiding cooperation between monitoring support and bearing bracket is to realize by offset axis 6 and the pilot hole passing for offset axis 6 on housing 11, and the location of the two is to realize by being filled in packing filling in housing 11 10, gland 12 is by packing filling compacting, and 10 pairs of offset axises 6 of the packing filling being compacted apply locating friction power upwards, meanwhile, in the axle sinking displacement process causing because of bearing bush abrasion, axle applies downward pressure on top surface by rolling body to bearing bracket, this pressure on top surface makes bearing bracket overcome locating friction power and corresponding moving down, housing inner chamber is packing cavity, packing filling is friction media.
The wear extent of bearing shell is the displacement of offset axis 6, and the displacement of offset axis 6 is directly measured realization by measurement mechanism, measurement mechanism comprises the scale of mark in the outside wall surface of housing 11, scale is by forming apart from six circular scale lines 3 that are 2mm between the upper and lower, offset axis 5 bottom screw threads at bearing bracket have been screwed upper and lower nut 1, between upper and lower nut 1, clamp pointer 2 that extend, that be used to indicate scale straight up, the wear extent of bearing shell can directly show by scale like this.In order to prevent that pointer 2 is because touching distortion, in housing outside wall surface, be also provided with the pointer chute embedding for pointer part, be slidably matched with pointer 2 guiding, to guarantee to react the true and accurate of displacement numerical value.
On the endoporus wall surface of the hole passing for bearing bracket of housing 11, be provided with spline chute, on the offset axis 5 of bearing bracket, convex with the spline body 4 coordinating with the sliding plug of spline chute guiding, can guarantee that like this offset axis 5 can only move axially and can not circumferentially rotate, guarantee contact position and the angle of roller 7 and axle.
When above-described embodiment is specifically applied on rotary drum vacuum filter, housing 11 be fixed on filter distribution head seal up a door bottom, the bottom of the axle that roller 7 coordinates with bearing shell to be measured in working order time all the time contacts, and be between the wear-resisting copper coin of dispensing head and bearing shell and install, packing filling 10 can prevent that bearing bracket from moving down automatically; When there is axle sinking displacement in bearing bush abrasion, roller 7 senses moving down of axle, and order about bearing bracket and move down together with pointer 2, in the wearing and tearing of constantly accumulating in equipment operation, until pointer 2 points to the warning scale mark of lower limit, then change a watt maintenance, guarantee rotary drum vacuum filter bearing shell in the situation that the normal of production run cycle generation can not be worn through with improper wearing and tearing.
In other embodiments, rolling body also can adopt round roller.
In other embodiments, friction media also can adopt fixed cover to be located at the rubber sleeve on offset axis, and certainly, monitoring support also can adopt the orienting sleeve inserting for offset axis gap, and rubber sleeve is arranged in the gap between offset axis and orienting sleeve.
In other case study on implementation, on offset axis, also can not establish pointer and corresponding scale mark, the method that adopts machinery to be combined with electronics, at displacement shaft end, electronics touching or induction installation are installed, after reaching warning shift value by offset axis, touching is reported to the police in hermetic cavity electricity contact formation path bright light or jingle bell, realize instrumented and far control the wear extent of bearing shell in the airtight body of rotary drum vacuum filter, avoid the generation of pernicious equipment failure.
The embodiment of rotary drum vacuum filter of the present utility model: comprise frame and be arranged on the bearing bush abrasion monitor in frame, as shown in Figure 1, consistent with the structure of monitor in above-described embodiment, its content does not repeat them here the structure of this monitor.
