Embodiment Construction

[0015] In the drawings, reference numeral 1 refers to a first mechanical element having a hole 1a comprising a tapered portion 1b, while reference numeral 2 refers to a second mechanical element 2 having a hole 2a closed at its second end and comprising a cone shaped part 2b. In order to connect the machine elements 1 and 2 to each other via the holes 1a and 2a, a locking bolt 3 with a joint sleeve 7 is installed.

[0016] The first end 5 of the locking bolt 3 in one side of the closed hole 2a is provided with a threaded portion 5a through which the locking bolt 3 is connected to a corresponding thread in the inner end of the hole 2a and thus to the on the actual mechanical element 2. The locking bolt comprises a flange means 6 having a radial guide surface 6a associated with the first end 5 . The second end of the locking bolt 3 is provided with an expansion part 4 with an engagement mechanism 4a for a suitable tool, eg a hexagonal wrench or a screwdriver for transferring t...

Abstract

A connection arrangement for connecting and locking machine elements or the like to each other, the first machine element (1) containing a bore (1a) extending therethrough and the second machine element (2) containing a bore (2a) closed at its second end and in which the said bores are arranged to be provided with a locking bolt (3) or the like having an adapter socket (7), whereby the locking bolt (3) is essentially arranged inside the adapter socket (7).The first end (5) of the locking bolt (3) in the side of the closed bore is provided with a threaded part (5a) for connection to the inside of the said closed bore (2a) said threaded part (5a) being arranged to be utilised both during locking and releasing the connection arrangement.The second end of the locking bolt (3)isprovided with an expansion part (4) having engagement means (4a) for a suitable tool for transmitting torque to the locking bolt (3) as well as a guide surface (4b) arranged to effect in the locked position of the connection arrangement on a radially extending engagement surface (7a) of the corresponding end of the adapter socket (7).The shell of the adapter socket (7) comprises a conical surface (7c) arranged to cooperate with corresponding conical surfaces (1b, 2b) arranged inside the said bores, whereby the said conical surfaces (1b, 2b, 7c) decrease in diameter towards the said closed end of the bore.

Description

technical field [0001] The invention relates to a connection device according to the preamble of claim 1 for connecting and locking mechanical elements etc. to each other, a first mechanical element comprising a hole through it and a second mechanical element comprising a closed and wherein the hole is arranged to be provided with a locking bolt or the like having an adapter socket or the like, whereby the locking bolt is arranged substantially within the adapter socket. The invention also relates to a locking bolt according to claim 5 as part of a connecting device. Background technique [0002] It is previously known to use locking pins comprising conical surfaces to achieve mutual locking and centering of mechanical elements. This allows the locking pin to be self-locking after tightening. One such solution is shown in EP 0824202 B1. This solution consists of a cylindrical joint sleeve with an adapter bolt inside, whereby a conical surface between the adapter sleeve an...
