UA140641U - ELASTIC COUPLING BILATERAL - Google Patents

Abstract

The two-sided elastic coupling contains external and internal half-couplings with internal and external protrusions and springs between them, of which the main springs are placed in a circle, and compensating with pre-compression - in radius. Between the inner protrusions of the outer half-clutch and the outer protrusions of the inner half-clutch are placed W-shaped springs with slight initial deformation so that the central sections contact them with the outer protrusions of the inner half-clutch, and the outer sections - with inner protrusions of the outer half-clutch.

Description

A useful model belongs to mechanical engineering, namely to the connection of shafts and the transmission of dynamic torques, mainly in the drives of mechanisms and machines.

A well-known elastic double-sided coupling (see patent of Ukraine for a utility model Mo 124308, IPC

E160 3/52, E160 43/20, bull. Mo 7, 04/10/2019), is the closest to the proposed useful model, which contains an external and internal half-coupling with internal and external protrusions and springs between them, of which the main springs are placed in a circle, and compensating springs with preliminary compression - in a radius.

The main disadvantage of the known elastic double-sided coupling is the structural complexity and, accordingly, insufficient reliability due to the presence of a significant number of elastic elements.

The basis of a useful model is the task of creating a design of an elastic two-way coupling, which will have a simpler design and be more reliable when transmitting dynamic torques.

The problem is solved by the fact that the coupling is elastic two-way, which contains an external and internal half-coupling with internal and external protrusions and springs between them, of which the main springs are placed in a circle, and compensating springs with preliminary compression - in a radius, according to a useful model, between M/-shaped springs with a slight initial deformation are placed on the inner protrusions of the outer half-coupling and on the outer protrusions of the inner half-coupling so that their central sections are in contact with the outer protrusions of the inner half-coupling, and the outer sections are in contact with the inner protrusions of the outer half-coupling.

The proposed elastic double-sided coupling has a simpler design and is more reliable when transmitting dynamic torques.

The essence of the useful model is explained by the drawings, where: in fig. 1 shows an elastic double-sided coupling, general view, longitudinal section; in fig. 2 shows what in fig. 1, section A-A; in fig. It is shown that in fig. 2, cross section A-A, the position of the parts when the rotational moment is transmitted clockwise; in fig. 4 shows what in fig. 2, section А-А, the position of the parts when the torque is transmitted counterclockwise; in fig. 5 shows a variant of the MU-shaped spring design.

The elastic double-sided coupling consists of two outer 1 and inner 2 half-couplings.

The outer half-coupling 1 contains a hub 3, a clip 4 with internal protrusions 5. The internal

The semi-coupling 2 is made in the form of a hub 6 and external projections 7. Between the internal projections 5 and external projections 7, MU-like springs 8 with a central section 9 and external sections 10 are placed.

The elastic double-sided coupling is assembled in the following sequence. The inner half-coupling 2 is inserted into the outer half-coupling 1. Next, we alternately place the M/-shaped springs 8 with the central section 9 on the outer protrusions 7 of the inner half-coupling 2, and the outer sections 10 rest on the inner protrusions 5 of the outer half-coupling 1. After completing the installation of the M/-like springs 8 clutch is ready for work.

The elastic double-sided coupling works like this. The torque from the half-coupling 1 is transmitted through the internal protrusions 5, M/-like springs 8 to the external protrusions 7 of the half-coupling 2. Due to the elastic properties of the M/-like springs 8, dynamic loads and axial, radial and angular inaccuracies of the shaft connection are compensated.

The proposed elastic double-sided coupling has a simpler design and is more reliable when transmitting dynamic torques.
