GOST 19115-91 Spring Track Washers. Technical Conditions

GOST 19115-91 applies to single-turn spring washers of product grade C used in railway track superstructure structures.

The requirements of the standard are mandatory, except for clause 2.3.

1. Design and dimensions

The design and dimensions of spring washers shall conform to those shown in the drawing and table. Designations in the drawing: D — washer diameter, h — washer thickness, b — washer width.

Example of designation for a spring washer of design 1 for a bolt with a diameter of 22 mm, made of steel grade 65G, without protective coating:

Washer 22 GOST 19115-91

Same, for design 2:

Washer 2.22 GOST 19115-91

Same, made of steel grade 60S2A:

Washer 22.60S2A GOST 19115-91

Design 2 washers are manufactured by agreement between the manufacturer and the customer.

2. Technical requirements

Basic technical requirements — per GOST 6402.

Spring washers are made from wire per GOST 11850, of steel grades 65G, 60S2A or other steel grades with mechanical properties not lower than those of steel grade 65G per GOST 14959. When steel grade 60S2A or other steels are used, the steel grade is indicated in the designation.

At the customer’s request, each washer after heat treatment shall be subjected to threefold compression to a flat state.

During the control check of spring properties after compressing the washers to a flat state for 24 h, the reduction of dimension H shall not exceed 0.8 mm.

The theoretical mass of the washers is given in the appendix.

Temporary corrosion protection, packaging of washers and container marking — per GOST 18160.

3. Acceptance

Acceptance rules — per GOST 17769 for products of product grade C.

Lot size from 10001 to 35000 pcs.

4. Control methods

Control methods — per GOST 6402, excluding toughness testing.

5. Transportation

Washers are transported by any mode of transport in accordance with the transportation rules applicable to that mode of transport.
