Abstract
A kind of rotary type duplex bearing land device, comprise land and driven disc, setting sleeve is arranged in the inner chamber side of described land, inner sleeve is arranged in the middle part of described inner chamber, the other end of described inner chamber installs two bearings be arranged side by side, the inner ring of described bearing is fixedly connected with described driven disc, and aluminum pipe stretches into described inner chamber and is connected with described driven disc.The utility model provide a kind of operate light, reduce vibrations, increase the rotary type duplex bearing land device in working life.
Description
Technical field
The utility model belongs to graden machine instrument, relates to a kind of land.
Background technique
In existing graden machine instrument, land device comprises land, driven disc, and described land is connected by a bearing with between driven disc.The defect existed is: operation effort, and vibrations are comparatively large, and working life is shorter.
Summary of the invention
In order to overcome the operation effort of existing land, vibrations are comparatively large, working life is shorter deficiency, the utility model provides and a kind ofly operates rotary type duplex bearing land device that is light, that reduce vibrations, increase working life.
The utility model solves the technological scheme that its technical problem adopts:
A kind of rotary type duplex bearing land device, comprise land and driven disc, setting sleeve is arranged in the inner chamber side of described land, inner sleeve is arranged in the middle part of described inner chamber, the other end of described inner chamber installs two bearings be arranged side by side, the inner ring of described bearing is fixedly connected with described driven disc, and aluminum pipe stretches into described inner chamber and is connected with described driven disc.
Further, the outer ring of described aluminum pipe has restraining groove, the inner chamber between setting sleeve and inner sleeve is installed the first shaft block ring, and described first shaft block ring embeds in described restraining groove.
Further, between described first shaft block ring and described setting sleeve, packing ring is set.
Further again, the side of one of them bearing is connected with the second shaft block ring, and described second shaft block ring is embedded in the circular groove of the axis of driven disc; The opposite side of another bearing is connected with the base of driven disc by the 3rd shaft block ring.
The beneficial effects of the utility model are mainly manifested in: 1, have employed dual bearing structure, effectively reduce vibrations, add operation instruction; 2, aluminum pipe is by the first shaft block ring location, and aluminum pipe can freely rotate, and easy-to-operat person operate at different direction.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of rotary type duplex bearing land device.
Fig. 2 is the schematic appearance of rotary type duplex bearing land device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
See figures.1.and.2, a kind of rotary type duplex bearing land device, comprise land 1 and driven disc 9, setting sleeve 3 is arranged in the inner chamber side of described land 1, inner sleeve 6 is arranged in the middle part of described inner chamber, the other end of described inner chamber installs two bearings 10 be arranged side by side, and the inner ring of described bearing 10 is fixedly connected with described driven disc 9, and aluminum pipe 2 stretches into described inner chamber and described driven disc and connects 9 and connect.
Further, the outer ring of described aluminum pipe 2 has restraining groove, the inner chamber between setting sleeve and inner sleeve is installed the first shaft block ring 5, and described first shaft block ring 5 embeds in described restraining groove.
Further, between described first shaft block ring 5 and described setting sleeve 3, packing ring 4 is set.
Further again, the side of one of them bearing is connected with the second shaft block ring 7, and described second shaft block ring 7 is embedded in the circular groove of the axis of driven disc; The opposite side of another bearing is connected with the base of driven disc 9 by the 3rd shaft block ring 8.
The present embodiment have employed dual bearing structure, effectively reduces vibrations, adds operation instruction; Aluminum pipe is by the first shaft block ring location, and aluminum pipe can freely rotate, and easy-to-operat person operate at different direction.
