Abstract
The utility model discloses a bucket-type elevator external bearing tail shaft device which comprises a bucket-type elevator tail shell (1), a tail shaft (2), a sealing gasket (3), a flange cover (4), a bracket body (5), a supporting bearing (6), a stuffy cover (7), an oil cup (8), an oil seal (9), grease packing (10), a bolt (11) and a packing gland (12). The bucket-type elevator external bearing tail shaft device is characterized in that the supporting bearing (6) is placed outside the bucket-type elevator tail shell (1) and is fixed through the bolt; the inner side of the supporting bearing (6) is provided with the oil seal (9) and is sealed, and the outer side of the supporting bearing (6) is provided with the stuffy cover (7) and sealed and ensures that the tail shaft (2) is axially positioned; the oil cup (8) is placed on the stuffy cover (7); the movable sealing element grease packing (10) is placed between the flange cover (4) and the tail shaft (2); and the bracket body (5) is provided with maintenance holes. The bucket-type elevator external bearing tail shaft device has the advantages of being high in working reliability, long in service life, convenient to replace, low in maintaining cost and the like.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of bucket elevator outboard bearing tailing axle device.
Background technology
The tailing axle device of existing bucket elevator, the backup bearing at its tailing axle two ends, it generally is slip nylon jacket structure in the casing housing the inside of gig, in actual applications, have the following disadvantages: the nylon jacket structure of sliding on the one hand places the tail enclosure interior, be easy to be reduced service life, and be difficult for changing by solid material accelerated wear test; The gig operating personal is difficult for observing the damage rate of slip nylon jacket structure and continues the start operation on the other hand, up to the slip nylon jacket, block set and tail housing gall, could find that the tailing axle device is badly damaged when solid material leaks, this must cause long-time stopping production and increase service expenditure.
Summary of the invention
Advantages such as at above-mentioned the deficiencies in the prior art, the utility model provides a kind of bucket elevator outboard bearing tailing axle device, and this device has functional reliability height, long service life, replacing is convenient, maintenance cost is low.
The technical solution of the utility model is: bucket elevator outboard bearing tailing axle device, comprise bucket elevator tail housing 1, tailing axle 2, packing seal 3, blind flange 4, protrusions 5, backup bearing 6, stifle 7, lubricating cup 8, oil sealing 9, grease packing 10, bolt 11, packing gland 12, it is characterized in that: described backup bearing 6 is arranged on the outside bolt of bucket elevator tail housing 1; The end face axial butt flange lid 4 and the protrusions 5 of the two ends flange gasket 3 of described bucket elevator tail housing 1, the backup bearing 6 at the two ends of tailing axle 2 places the bearing chamber of protrusions 5; Described backup bearing 6 inboards are provided with oil sealing 9 sealings, and its arranged outside stifle 7 seals and make tailing axle 2 axial location; Described stifle 7 is provided with lubricating cup 8; Dynamic seal grease packing 10 is set between described blind flange 4 and the tailing axle 2; Described protrusions 5 is provided with service hatch.
The utility model has the advantages of and be: this bucket elevator outboard bearing tailing axle device, the not frayed fully and energy oil injecting lubricating of the backup bearing of tailing axle; Can adjust the dynamic seal of grease packing and make and adjust and to change sealing member faster, this device has improved the functional reliability of bucket elevator, has prolonged service life, has reduced maintenance time, has reduced service expenditure and the loss that stops production.
