Abstract
The utility model relates to a hoisting device for bearings, the utility model is used in a helical conveyor, the original sliding friction is changed into rolling friction, and the utility model is composed of a connecting shaft, a bearing, an upper seat, a lower seat, etc. The utility model is characterized in that at least two bearings are arranged on the middle shaft neck of the connecting shaft, and the bearings are fixed on the upper seat and the lower seat. The device has simple structure, small conveying resistance, long service life, low manufacturing cost and low using and maintenance cost.
Description
The utility model relates to a kind of material transfer equipment, the suspension bearing device that particularly a kind of conveyor screw is used.
Conveyor screw is a kind of widely used material transfer equipment, the suspension bearing device is the parts of this office's key, the structure design quality of this device, directly influence the serviceability of complete machine, at present, the version of the suspension bearing device that conveyor screw adopted is varied, and what be most widely used is slip suspension bearing device with bearing shell supporting adapter shaft, but there are a series of deficiencies in this device: (1) is lubricated, sealing is unreliable; (2) bearing shell and adapter shaft quick abrasion are changed frequent; (3) friction drag is big, the energy consumption height; (4) manufacturing and use service expenditure are big.
The purpose of this utility model provides a kind of suspension bearing device that is used for conveyor screw, replaces existingly supporting adapter shaft with bearing shell with several antifriction-bearing boxs, becomes original cliding friction and is friction of rolling.
Solution is: this suspension bearing device is made up of adapter shaft, bearing, the seat of honour and following, it is characterized in that being provided with at least two bearings that are fixed in the seat of honour and following in the adapter shaft intermediate journal.
Its advantage is: this suspension bearing apparatus structure is simple, and commonality is good, and comformability is strong, and rotary resistance is little, long service life, and manufacturing and use cost of maintenance are low.
Description of drawings:
Fig. 1 is a suspension bearing device cutaway view of the present utility model.
Fig. 2 is the cut away left side view of Fig. 1.
Below in conjunction with drawings and Examples, essence of the present utility model is further described.
As depicted in figs. 1 and 2, this suspension bearing device is made up of adapter shaft 1, two bearings 4 and corresponding bearing pin 3 thereof and axle sleeve 5 and the seat of honour 2, following 7 and felt collar 6 at least, adopt the bearing 4 of the antifriction-bearing box of 0 class or 1 class, bearing pin 3, axle sleeve 5 is installed in respectively on the seat of honour 2 and following 7, and make bearing 4 place the seat of honour 2 and following 's 7 inner chamber, adapter shaft 1 is contained between the seat of honour 2 and following 7, the seat of honour 2 links to each other with following 7 bolt ups, promptly is equivalent to install at the intermediate journal place of adapter shaft 1 at least two bearings 4 that are fixed in the seat of honour 2 and following 7 and supports adapter shaft 1.Like this, there is a position of determining at the adapter shaft 1 relative seat of honour 2 with following 7, and can relatively rotate.Between the adapter shaft 1 and the seat of honour 2 and following 7, adopt labyrinth and felt collar combination sealing, promptly be provided with labyrinth on adapter shaft 1, be provided with maze trough and seal groove among the seat of honour 2 and following 7, this combination sealing is simple and reliable.
Adapter shaft 1 two ends are connected with the conveyor screw of conveyor screw, and hang on the casing stay bearing plate of conveyor screw at the seat of honour 2.
May be obvious that from embodiment described above, adapter shaft 1 is friction of rollings with the outer ring of bearing 4, add the combination sealing method that adopts actv. labyrinth and felt collar, significantly improved the service life of suspension bearing device, thereby improve complete machine operation factor and reduction manufacturing and use service expenditure.
Claims (4)
1, a kind of suspension bearing device is made up of adapter shaft, bearing, the seat of honour and following, it is characterized in that being provided with on adapter shaft (1) intermediate journal at least two bearings (4) that are fixed in the seat of honour (2) and following (7).
2, device as claimed in claim 1 is characterized in that this bearing (4) is the antifriction-bearing box of 0 class or 1 class.
