Abstract
The utility model relates to a sheath type support wheel mechanism, which comprises a support frame (9), a pressing upper cover (4), a regulation screw rod (2), a pressing hand wheel (1), a gas expansion shaft (8) and two bearings (7), wherein the pressing hand wheel (1) is connected with the regulation screw rod (2) through screw threads, the regulation screw rod (2) is hinged with the support frame (9) through a first pin (3), the pressing upper cover (4) is hinged with the support frame (9) through a second pin (10), the gas expansion shaft (8) is supported on the support frame (9), the two bearings (7) are respectively sheathed on the gas expansion shaft (8), an isolation sleeve (6) is additionally arranged between the two bearings (7), the outer sides of the bearings (6) are fixed with bearing sleeves (5) through clamp springs, the bearing sleeves (5) are also sheathed on the gas expansion shafts (8), and the pressing upper cover (4) covers the bearings (6). The sheath type support wheel mechanism has the advantages that the service life of the gas expansion shaft can be greatly prolonged, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of protective-cover type wheel holding mechanism, is used for the retractable volume of various web apparatus.
Background technology
In general-duty material carrying mechanism in the past (shown in accompanying drawing 1,2), the inflatable axle often directly places bearing surface to rotate, and must form to hob.Because product itself is heavier, bearing surface hardness will be hindered the inflatable axial compression in very short time far above the superficial hardness of inflatable axle, the service life of inflatable axle is far below the service life of bearing, also very under the news, the inflatable axle is just damaged by pressure, can not normally use at bearing.
Summary of the invention
The purpose of this utility model provides and a kind ofly can improve the inflatable axle protective-cover type wheel holding mechanism in service life greatly.
The technical scheme that realizes above-mentioned purpose is: a kind of protective-cover type wheel holding mechanism, comprise carriage, compress loam cake, adjust screw rod, compress handwheel, inflatable axle and two bearings, compressing handwheel is connected with the adjustment screw flight, it is hinged with carriage by first pin to adjust screw rod, it is hinged with carriage by second pin to compress loam cake, the inflatable axle is bearing on the carriage, two bearings all are sleeved on the inflatable axle, and between two bearings, install spacer additional, the bearing outside is fixed with bearing carrier ring by jump ring, bearing carrier ring also is sleeved on the inflatable axle, compresses loam cake and covers bearing.
After adopting technique scheme, two bearings all are sleeved on the inflatable axle, and between two bearings, install spacer additional, the inflatable axle is bearing on the carriage by bearing, thereby the inflatable axle do not contact with bearing outside surface, can not form to hob, the phenomenon that bearing surface weighs the inflatable axle wounded can not appear, make improve more than 5 times the service life of inflatable axle, greatly reduce productive costs far above the service life of bearing the service life of inflatable axle.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 3 ~ 8, a kind of protective-cover type wheel holding mechanism, comprise carriage 9, compress loam cake 4, adjust screw rod 2, compress handwheel 1, inflatable axle 8 and two bearings 7, compressing handwheel 1 is threaded with adjustment screw rod 2, it is hinged with carriage 9 by first pin 3 to adjust screw rod 2, it is hinged with carriage 9 by second pin 10 to compress loam cake 4, inflatable axle 8 is bearing on the carriage 9, two bearings 7 all are sleeved on the inflatable axle 8, and between two bearings 7, install spacer 6 additional, bearing 6 outsides are fixed with bearing carrier ring 5 by jump ring, and bearing carrier ring 5 also is sleeved on the inflatable axle 8, compress loam cake 4 and cover bearing 6.
Principle of work of the present utility model is as follows:
After compressing handwheel 1 and unclamping, open and compress handwheel 1, and then open compress loam cake 4(shown in Fig. 7,8), inflatable axle 8 and bearing carrier ring 5 can be taken out together.Operation and maintenance is very convenient.During installation, be placed on the carriage 9 as long as will load onto inflatable axle 8 integral body of bearing 7, spacer 6 and bearing carrier ring 5, and then close compress loam cake 4(shown in Fig. 3,4), and will adjust screw rod 2 and adjust to vertical position shown in Figure 3 with compressing handwheel 1.
Claims (1)
1. protective-cover type wheel holding mechanism, comprise carriage (9), compress loam cake (4), adjust screw rod (2), compress handwheel (1), inflatable axle (8) and two bearings (7), compressing handwheel (1) is threaded with adjustment screw rod (2), it is hinged with carriage (9) by first pin (3) to adjust screw rod (2), it is hinged with carriage (9) by second pin (10) to compress loam cake (4), inflatable axle (8) is bearing on the carriage (9), it is characterized in that: two bearings (7) all are sleeved on the inflatable axle (8), and between two bearings (7), install spacer (6) additional, bearing (6) outside is fixed with bearing carrier ring (5) by jump ring, bearing carrier ring (5) also is sleeved on the inflatable axle (8), compresses loam cake (4) and covers bearing (6).
