Abstract
The utility model discloses a pulley bearing box for slicing equipment. The pulley bearing box comprises a shell and a core; the core comprises a rear sealing cover, an inner sealing ring, an inner bearing, a bearing adjusting ring, an outer ring, an elastic washer and a bearing front end cover sequentially sleeved on a fixing screw, and is locked and fixed through a shaft shoulder structure on the fixing screw; the fixing screw has hollow structure; and the shell is sleeved on the core, the shell is sealed with the rear sealing cover through a stacked sealing ring, an inward protruded structure is arranged in the shell, the end face of the inward protruded structure is in contact with the lateral surface of the outer ring of the inner bearing, the lateral surface of the inward protruded structure is in contact with that of the inner sealing ring, the clearance formed between the shell and the inner sealing ring is communicated with the hollow cavity of the fixing screw, and the shell is fixed with the bearing front end cover. The bearing box has simple structure, and the service life of the bearing box is effectively prolonged; and through the bearing box, a device is easy and convenient to install and maintain, and only the bearing rather than the whole set of the device is replaced after the device is damaged, so that the maintenance cost is greatly reduced.
Description
Technical field
The utility model relates to chopper and slicer, relates in particular to a kind of chopper and slicer and uses the pulley bearings case.
Background technique
The pulley bearings case of existing slicer is general to adopt folded ring sealing to add the method for hermetic seal, and its sealing part gap is big, and the aluminium shell of bearing housing and bearing outer ring adopt interference fit to fix.Use down at the mal-condition that mortar spray is arranged and run up, cause easily that mortar is stuck, pulley rocks problems such as big, cause device damage, cause production process to interrupt problems such as wire jumper, and install and inconvenience.
The model utility content
Goal of the invention: in order to overcome the deficiency that exists in the existing technology, the utility model provides a kind of good airproof performance, the pulley bearings case of long service life.
Technological scheme: for solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of chopper and slicer is used the pulley bearings case; Comprise shell and core body; Said core body comprises back sealing cover, inner seal ring, inner bearing, bearing adjustment ring, outer bearing, elastic washer, bearing front cover and set screw; Said set screw is a hollow structure; And on set screw, be provided with shaft shoulder structure, back sealing cover, inner seal ring, inner bearing, bearing adjustment ring, outer bearing, elastic washer and bearing front cover are sleeved on the set screw successively, and the parts that will be sleeved on the set screw through shaft shoulder structure are locked on set screw; Outer cover suit is on core body; Seal through folded ring seal ring between shell and the back sealing cover; Portion is provided with projecting inward structure in the enclosure, the outer ring contacts side surfaces of the end face of said projecting inward structure and inner bearing, the side of projecting inward structure and the contacts side surfaces of inner seal ring; The gap that forms between shell and the inner seal ring is communicated with the hollow cavity on the set screw, and shell and bearing front cover fix.
The mode that above-mentioned pulley bearings case, its hermetic unit adopt outside folded ring sealing to combine with the inner seal ring that has increased hermetic seal, the fixed bearing section employing elastic washer mode that combines with the bearing front cover.
Wherein, the set screw design shaft shoulder adopts little Spielpassung and inner seal ring, bearing and bearing adjustment ring etc. together to be locked with the back sealing cover, makes whole device quality of fit comparatively accurate; Adopt less matching gap between shell and the back sealing cover, increase the effect of first road sealing; Simultaneously between internal bearings and shell, increased inner seal ring; Bearing outer ring and shell are less Spielpassung; Bearing inner race cooperates with set screw, is vented to gap between inner seal ring and the shell through hollow hole in the set screw simultaneously and is blown out by special air port and form hermetic seal.
Shell and bearing outer ring adopt Spielpassung, and it axially adopts elastic washer to add bearing front cover axial compression; The number of bearing is two, is positioned at bearing adjustment ring both sides, is designated as inner bearing and outer bearing, and design inner bearing and outer bearing for installation and maintenance are convenient fixing all in same direction.
Beneficial effect: the chopper and slicer that provides of the utility model is used the pulley bearings case, and is simple in structure, effectively improved bearing housing working life; Unit Installation is safeguarded become simple and convenient, can only change bearing after the damage and need not to change package unit, reduce maintenance cost greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be illustrated in figure 1 as a kind of chopper and slicer and use the pulley bearings case; Comprise shell 1 and core body; Said core body comprises back sealing cover 2, inner seal ring 3, inner bearing 8, bearing adjustment ring 4, outer bearing 10, elastic washer 5, bearing front cover 6, set screw 7; Said set screw 7 is a hollow structure; And on set screw 7, be provided with shaft shoulder structure, back sealing cover 2, inner seal ring 3, inner bearing 8, bearing adjustment ring 4, outer bearing 10, elastic washer 5 and bearing front cover 6 are sleeved on the set screw 7 successively, and the parts that will be sleeved on the set screw 7 through shaft shoulder structure are locked on set screw 7; Shell 1 is sleeved on the core body; Seal through folded ring seal ring 9 between shell 1 and the back sealing cover 2; Be provided with projecting inward structure in shell 1 inside, the outer ring contacts side surfaces of the end face of said projecting inward structure and inner bearing 8, the contacts side surfaces of the side of projecting inward structure and inner seal ring 3; The gap that forms between shell 1 and the inner seal ring 3 is communicated with the hollow cavity on the set screw 7, and shell 1 and bearing front cover 6 fix.
Said inner bearing 8 is fixing all in same direction with outer bearing 10.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
