Abstract
The utility model discloses a dustproof sealing structure for bearings of breakers. The dustproof sealing structure comprises a dustproof cover, a bushing, lock nuts, a cooling air tube and a cleaning iron sheet. The interval between the inner bore of the dustproof cover and the outer wall of the bushing ranges from 2mm to 3mm, and the cooling air tube penetrates through cooling air tube holes arranged on a casing of the dustproof cover and extends into the dustproof cover. The dustproof sealing structure is simple in structure, low in modification cost and fine in sealing effect, enables fault rate of the bearings to be lowered greatly so that great cost for maintenance is saved every year, and further improves production efficiency, increases incomes and improves field environment management.
Description
Technical field
The utility model relates to a kind of bearing dust-proof sealing structure, particularly relates to a kind of beater bearing dust-proof sealing structure.
Background technology
Our factory is because cement grinding mill beater dust cover housing endoporus and propeller shaft tube gap (20mm) too greatly; And, piles up equipment a large amount of dust when moving on the dust cover; Cause dust to enter in the dustproof case and seal friction, shortened the service life of beater bearing dust-proof seal ring greatly from dust cover endoporus and propeller shaft tube gap location.Beater bearing dust-proof seal ring damages, and ash is advanced in bearing inside, causes in the bearing and the interior greasy filth that all form of oil pocket, makes the beater bearing temperature high, and current of electric is high, and bearing damages because of insufficient lubrication.The damage of bearings rate is high, has increased the cost of overhaul greatly, and damage of bearings causes shutting down maintenance simultaneously, has reduced the production efficiency and the income of factory.This beater of our factory is introduced by Canadian FULLER (Fu Le) company.
The utility model content
The purpose of the utility model is to provide a kind of beater bearing dust-proof sealing structure.
The purpose of the utility model is implemented by following technical scheme; A kind of beater bearing dust-proof sealing structure; It comprises dust cover, axle sleeve, locking nut, and it also includes cooling duct and cleaning iron plate, and the gap of said dust cover endoporus and said axle sleeve outer wall is 2-3mm; Said dust cover housing is provided with the cooling air pore; Said cooling duct passes said cooling air pore and stretches in the said dust cover, and said cleaning iron plate is fixed on the said locking nut, and said cleaning iron plate becomes 120 ° of-125 ° of angles with the cross section of said locking nut.
The gap of pitch-row axle sleeve in the dust cover is dwindled, and in dust cover, add cooling duct, be blown into gas, make the interior malleation that produces of dust cover effectively to have prevented the gap location entering of dust from dust cover and axle sleeve through cooling duct; Install a cleaning iron plate on the locking nut of power transmission shaft additional, the dust on the cleaning dust cover housing guarantees the cleaning of the dust on the dust cover housing totally and with dust is sent flying.
The advantage of the utility model is that the utility model is simple in structure, and improvement cost is low, good sealing effect, and the damage of bearings rate reduces greatly, a large amount of costs of overhaul of annual saving; Promote the raising of production efficiency and income; Facilitation has been played in environmental improvement work to the scene.
Description of drawings
Fig. 1 is a kind of beater bearing dust-proof sealing structure figure.
The specific embodiment: a kind of beater bearing dust-proof sealing structure; It comprises dust cover 1, axle sleeve 2, locking nut 3, and it also includes cooling duct 4 and cleaning iron plate 5, and the gap of dust cover 1 endoporus and axle sleeve 2 outer walls is 2-3mm; Dust cover 1 housing is provided with the cooling air pore; Cooling duct 4 passes the cooling air pore and stretches in the dust cover 1, and cleaning iron plate 5 is fixed on the locking nut 3, and cleaning iron plate 5 becomes 120 ° of-125 ° of angles with the cross section of locking nut 3.
