Abstract
The utility model discloses an integrated type dismounting device for bearings in a bearing box. The integrated type dismounting device for the bearings in the bearing box is composed of nuts, supporting frames, guide pieces, rolling bearings, chucks, double-line rolling bearings, bolts and the bearing box, wherein a threaded through hole in each guide piece is locked by each nut, and the guide pieces are in locking connection with the chucks through the bolts and the nuts. The integrated type dismounting device for the bearings in the bearing box has the advantages of being simple in structure, convenient to dismount, and small in loss.
Description
Technical field
The utility model relates to a kind of stator blade adjustable shaft flow fan transmission system field, and the utility model specifically is used for the provision for disengagement of a kind of solid box axle box bearing of stator blade adjustable shaft flow fan transmission system.
Background technology
Stator blade adjustable shaft flow fan is widely used in flue gas in metallurgy sintering smoke pressurizing desulfurizing system, the seawater desulfurization device and carries the sending of pressure charging system and large thermal power plant coal-burning boiler, induced draught system etc. in recent years.Therefore, increase along with stator blade adjustable shaft flow fan quantity, its many Maintenance and Repair problems occur again and again, wherein particularly outstanding especially on the dismounting problem of transmission system middle (center) bearing case middle (center) bearing, mainly there is following shortcoming: 1, adopt traditional method of tolling breakdown, bearing after its dismounting is scrapped, and can't again utilize; When 2, dismantling bearing, bearing housing is damaged, causes scrapping, increased maintenance cost.
The utility model content
The utility model is intended to overcome above-mentioned technological deficiency, and purpose provides a kind of simple in structure, convenient disassembly, the provision for disengagement of losing little solid box axle box bearing.
For achieving the above object, the technical solution adopted in the utility model is: be comprised of nut, support, guide, rolling bearing, chuck, double-row bearing, bolt, bearing housing; Screw thread on the guide passes the hole and pins by nut; Guide is connected by bolt, nut check with chuck.
Because adopt technique scheme, the utility model has been saved cost on stator blade adjustable shaft flow fan Maintenance and Repair problem; Use the bearing after the utility model maintenance is dismantled again to utilize, be unlikely to directly to scrap; Reduced simultaneously the damage to bearing housing, greatly reduced bearing housing and cause the situation of scrapping because of removal reasons; The utility model also has good effect for the dismounting of many rows bearing.

The specific embodiment
Below in conjunction with accompanying drawing the utility model being further described, is not the restriction to its protection domain.
A kind of provision for disengagement of solid box axle box bearing is comprised of nut (1), support (2), guide (3), rolling bearing (4), chuck (5), double-row bearing (6), bolt (7), nut (8), bearing housing (9).
The guide of this specific embodiment (3) has holddown groove (3a), chuck (5) can not be offset when the dismounting bearing, guarantee rolling bearing (4) and double-row bearing (6) dismounting stress equalization, prevent that discontinuity equalization from causing being offset stuck, also reduces simultaneously the damage to bearing housing (9).
The guide of this specific embodiment (3) has screw thread (3b), then screw thread (3b) passes hole (2a), be screwed on the screw thread (3b) by nut (1), the drop-down action-oriented spare of supporting role (3) and chuck (5) at support (2), chuck (5) is affixed on rolling bearing (4) and the double-row bearing (6), rolling bearing (4) and double-row bearing (6) are slowly moved to bearing housing (9) two ends under the effect of nut (1) screwing force, reach the function of reliable and stable dismounting bearing.
The chuck of this specific embodiment (5) has kidney slot (5a), according to the size of rolling bearing (4) with double-row bearing (6) external diameter, can adjust mobile top (5b) by kidney slot (5a) gos deep in groove (9a), the groove (9b), guaranteed that the utility model still can satisfy reliable dismounting requirement when the transmission system bearing housing of dismounting different model.
The bearing housing of this specific embodiment (9) is provided with groove (9a), groove (9b), and chuck (5) and rolling bearing (4), double-row bearing (6) stress surface are increased, and reduces the damage of rolling bearing (4) with double-row bearing (6).
Therefore, the utility model is a kind of simple in structure, convenient disassembly, the provision for disengagement of losing little solid box axle box bearing.
Claims (5)
