Abstract
The utility model discloses a thin-wall shaft end supporting assembly which comprises a thin-wall supporting structural part, a gear shaft, a cone check ring and a cone pressing sleeve. One end of the gear shaft is matched with inner holes of the cone check ring and the cone pressing sleeve. The excircle of the cone check ring is in clearance fit with a supporting hole of the thin-wall supporting part. When the thin-wall shaft end supporting assembly is installed, matched conical surfaces between the cone pressing sleeve and the cone check ring are mutually squeezed by screwing down a bolt, so that the diameter of the excircle of the cone check ring is increased to be in interference fit with the supporting hole of the thin-wall supporting part from clearance fit under a free state, and thus, one end of the gear shaft is well fixed and supported on the thin wall supporting part. The thin-wall shaft end supporting assembly has the characteristics that the thin-wall shaft end supporting assembly has simple structure, is convenient to mount and disassemble and the like.
Description
Technical field
The utility model relates to bavin Machine Components and Parts Design field, and a kind of specifically end at axle need be supported on back shaft end structure under the situation of thin-walled component, and prerequisite is that this root axle is static for relatively with the thin-wall part that supports it.
Background technique
Well-known axle is that a lot of motion revolving parts bear the carrier of axial force, radial force, and axle has two kinds of working staties of motion and standstill.It must be with the two ends fixed support of axle when design.The two ends of general first-selected back shaft be through bearing with the two end supports of axle in the bearing hole of two-end structure spare.But bearing is the state specified standards component, when the wall thickness of need installation shaft bearing structure spare is extremely thin, is thinned in the time of can't holding a bearing width to come the support fixation axle head to realize with bearing more at this moment.
The model utility content
A kind of axle head fixed support structure that designs in order in a thin walled structures spare, to support axle head.The utility model is simple in structure, supports reliably, can in product specification, promote.
The technological scheme that the utility model adopts:
A kind of axle head fixed support assembly; Include taper gland, taper back-up ring, hold-down bolt, axle and thin-wall support structural member, the outer wall of said taper gland is provided with male cone (strobilus masculinus), and the central position of said taper gland is provided with bolt hole; The inwall of said taper back-up ring is provided with inner conical surface; The axle head mounting hole is established at said taper back-up ring center, and said axle head center is provided with tapped hole, and said taper gland is installed in the said thin walled structures spare center hole; Said hold-down bolt passes taper gland and taper back-up ring and is screwed in the axle head screwed hole of centre, can the interior circle and the taper gland one end cylindrical of taper back-up ring be carried out cone match.
Said taper back-up ring is enclosed within an end of axle when installing, adopt Spielpassung between back-up ring cylindrical and the thin walled structures spare mounting center hole.
The utility model is a kind ofly can in a thin walled structures spare, support a kind of axle head fixed support structure that axle head designs, and its chief component has taper gland, taper back-up ring, hold-down bolt, axle and thin-wall support structural member etc.Be enclosed within an end of axle when wherein the taper back-up ring is installed, adopt Spielpassung between back-up ring cylindrical and the thin walled structures spare mounting center hole, there is tapped hole at the axle head center; The taper gland is installed in the thin walled structures spare center hole.The interior circle of taper back-up ring and taper gland one end outer conical surface cooperate.Pass taper gland and taper back-up ring with a standard bolt during installation and be screwed in the axle head screwed hole of centre and tighten.Impacting force through bolt makes the taper gland be pressed in the internal taper hole of taper back-up ring like this, thereby the cylindrical of taper back-up ring is expanded to reach and the fixing effect of the interference fit of thin walled structures spare.Axle head promptly well is fixedly supported in the thin walled structures spare like this.

Embodiment
Referring to accompanying drawing, a kind of axle head fixed support assembly includes taper gland 5, taper back-up ring 2, hold-down bolt 4, axle 3 and thin-wall support structural member 1; The outer wall of said taper gland 5 is provided with male cone (strobilus masculinus); The central position of said taper gland 5 is provided with bolt hole, and the inwall of said taper back-up ring 2 is provided with inner conical surface, and the axle head mounting hole is established at said taper back-up ring 2 centers; Said axle 3 end centers are provided with tapped hole; Said taper gland 5 is installed in said thin walled structures spare 1 center hole, and said hold-down bolt 4 passes taper gland 5 and taper back-up ring 2 and is screwed in the axle head screwed hole of centre, can the interior circle and the taper gland 5 one end cylindricals of taper back-up ring 2 be carried out cone match.
Claims (2)
1. axle head fixed support assembly; Include taper gland, taper back-up ring, hold-down bolt, axle and thin-wall support structural member, it is characterized in that: the outer wall of said taper gland is provided with male cone (strobilus masculinus), and the central position of said taper gland is provided with bolt hole; The inwall of said taper back-up ring is provided with inner conical surface; The axle head mounting hole is established at said taper back-up ring center, and said axle head center is provided with tapped hole, and said taper gland is installed in the said thin walled structures spare center hole; Said hold-down bolt passes taper gland and taper back-up ring and is screwed in the axle head screwed hole of centre, can the interior circle and the taper gland one end cylindrical of taper back-up ring be carried out cone match.
2. according to the said axle head fixed support of claim 1 assembly, it is characterized in that: said taper back-up ring is enclosed within an end of axle when installing, adopt Spielpassung between back-up ring cylindrical and the thin walled structures spare mounting center hole.
