The manufacturer of Spline bushing tells you that the spline connection consists of an internal spline and an external spline. The inner and outer splines are multi-tooth parts, the splines on the inner cylindrical surface are inner splines, and the splines on the outer cylindrical surface are outer splines. Obviously, the spline connection is the development of the flat key connection in terms of number. The spline is a standard structure. The flat key connection is often used for the connection of gears or couplings with interference fits and shafts. Spline bushing manufacturers tell you that there is usually no interference in the spline connection, so the connected parts need to be axially fixed. The spline is fast, easy and excellent. The spline connection has high load-bearing capacity and good alignment, but the manufacturing cost is high, and it needs to be processed with a special tool.

Bushing inspection standard:
1. The Spline bushing manufacturer tells you that the surface of the sample should be free of bubbles, burrs, deformation, uniform material, and no irritating odor.
2. Size
(1) Testing related dimensions with vernier calipers should meet the requirements of related technologies and drawings.
(2) After the shaft sleeve is matched with the rotating shaft, the rotor is vertically downward, and the shaft sleeve will not slide freely under the action of its own weight.
3. Heat resistance and aging resistance test
(1) After the sample is subjected to the 125℃/1h ball pressure test, the indentation should be ≤2mm, and there is no deformation by visual inspection.
(2) After putting the sample in the oven at 120°C/96 hours, visually check that the shaft sleeve has no embrittlement or deformation.
4. Combustion resistance test
The flame retardant grade is VW-1, and it should be extinguished within 15S after burning with alcohol lamp for 15S.
5. Packaging and logo
(1) The Spline bushing manufacturer tells you that the packaging should be firm, reliable and safe to ensure that the product is not damaged during transportation.
(2) The Spline bushing manufacturer tells you that the supplier's code and name, product name, product quantity, material code, quality inspection mark, production date, etc. should be indicated on the packaging. The mark should be clear and accurate, and there should be no mixed packaging.
(3) The Spline bushing manufacturer tells you that in order to increase the traceability of the product, it is required to mark the production batch number in a conspicuous place on the outer packaging. The supply lot number should be indicated on the product's inspection certificate or the original record of the inspection (experiment).
6. The content of hazardous substances (RoHS Directive)
The manufacturer of Spline bushing tells you that if it is used in RoHS directive models, the materials should comply with the RoHS directive requirements.
The above six points are the inspection standards for Spline bushing products. Welcome to inquire.
