Description
Technical field
The invention belongs to the machinery field, relate in particular to a kind of dismounting shaft end supporting device and have the rubber roll husker of this shaft end supporting device easily.
Background technique
On the main shaft of many equipment, because the mode of structure that needs the workpiece of often changing, main shaft to adopt an end support, the other end cantilever is installed, for reducing or eliminating the vibration of such main shaft cantilever end, usually at the main shaft cantilever end, increase aiding support.Axle head aiding support commonly used uses bearing to support mostly at present, if the axle of this class shaft end supporting device adopts routine to coordinate with bearing inner race, exists the inconvenient and frequent dismounting of dismounting to cause axle head to damage; If make to leave certain interval between axle and bearing inner race, meet easy accessibility, axle and bearing will disalignments and are affected the supporting positioning precision, cause supporting the problems such as unreliable.
Rice huller paddy is one of critical process of rice production, and the paddy operation of hulling at present mainly adopts rubber roll husker to complete the shelling of paddy.The groundwork member of rubber roll husker is the paddy hulling rubber roll of a pair of differential speed rotation in opposite directions, and paddy hulling rubber roll is arranged on 2 main shafts, and needs often to change rice huller paddy.Rubber roll husker is according to the length difference of its rubber roll, and the supporting way of the structure of its rubber roll and 2 main shafts is also different.General rubber roll length adopts wheeled construction at 10 inch and with interior paddy hulling rubber roll, and length adopts nested structure at 14 inch and above paddy hulling rubber roll; In the past, rubber roll length all adopted cantilever support at 10 inch with 2 main shafts of interior hulling machine, and 2 main shafts of the hulling machine of rubber roll length more than 14 inch all adopt two-end bearing support.The cantilever support rubber roll husker adopts Synchronous Belt Drives, there is no gearbox, its drive mechanism is compact, noise is little, in recent years along with the fractional yield of cantilever support structure hulling machine is high, change highlighting of the series of advantages such as rubber roll facilitates, cantilever support structure is widely applied on hulling machine, but also there are while moving shortcomings such as easily causing rubber roll working surface generation tapering, grooving in the cantilever support hulling machine.For overcoming the above problems, the cantilever end at cantilever support structure increases aiding support usually.While because of rubber roll, working, the speed roller needs often transposing and changes, and paddy hulling rubber roll main shaft cantilever end secondary support means one is to want to meet that rubber roll is changed, dismounting is convenient, and the 2nd, to guarantee accurately location and reliable supporting, the 3rd, simple in structure, long service life.
China Patent No. is that 200720063777 rice huller rubber roll supporting device and the patent No. are 200920259468 rice huller side plate type rubber roller auxiliary supporting device, all to be provided with an auxiliary bearing holder assembly bearing device at paddy hulling rubber roll main shaft cantilever end, between rubber roll main shaft and bearing inner race, be provided with axle sleeve, the outstanding of rubber roll main shaft goes out to hold Shen to enter in axle sleeve, the gap that main shaft hangs between end and inner hole of shaft sleeve is larger, the dismounting when being convenient for changing rubber roll.Although the secondary support means of above 2 patented technology introductions can meet the requirement of convenient disassembly substantially, but because hanging the end main shaft and the inner hole of shaft sleeve gap is larger, hang the end main shaft not exclusively coaxial with bearing inner race, make setting accuracy and the reliability of hanging the end main shaft supporting have a greatly reduced quality, affect work and the stability of two rubber rolls, likely make rubber roll produce a certain amount of CONCENTRIC REDUCER or make the cantilever end main shaft produce vibration etc.Because hulling machine working environment dust is many, dust is easily advanced in the gap that hangs between end main shaft and axle sleeve simultaneously, and equipment downtime also can affect dismounting during the long period.
