Axial play of constant speed gear 2 tapered roller bearing

mm

0,02...0,08

1

Preload the tapered roller bearings using adjusting sleeve  (3) while turning constant speed gear 2 (6).

 The tapered roller bearings are sufficiently preloaded when the 2 (6) becomes difficult to turn.

2

 Loosen adjusting sleeve (3) slightly.

3

Turn constant speed gear 2 (6) several times while tapping the constant speed gear 2 (6) using a plastic mallet.

 To release stresses.

4

 Screw on adjusting sleeve (3) again slightly by hand.

5

 Attach dial indicator (1) to  adjusting gauge (2).

 If the pin of the  dial indicator (1) is too short, use the  extension.

6

 Attach adjusting gauge (2) so that it slides on  adjusting sleeve (3).

7

Use  dial indicator (1) to measure to collar of main shaft (4).

8

 Set dial indicator (1) to zero.

9

Using  dial indicator (1), measure to collar of tapered roller bearing (5), dimension "A".

10

Calculate thickness of shim to be inserted.

 Dimension "A"- 0.20 mm= Thickness of shim to be inserted.

11

Using a suitable pulling device, pull off constant speed gear 2 (6) until an axial play of approx. 1.0 mm is reached.

12

Fit calculated shim (8) and pressure plate (7) on collar of journal.

13

 Fit adjusting sleeve (3) and tighten until the pressure plate (7) has pushed the tapered roller bearing back into its installation position.

14

 Attach dial indicator (1) to  adjusting gauge (2).

15

 Attach adjusting gauge (2) so that it slides on   adjusting sleeve (3).

16

 Position dial indicator (1) on ground surface of constant speed gear 2 (6) and turn constant speed gear 2 (6) approx. 20 times.

17

 Set dial indicator (1) to zero.

18

Turn constant speed gear 2 (6) in both directions slightly and, while simultaneously pushing up/down (arrows), read off bearing play at   dial indicator (1).

 Do not use a screwdriver or assembly iron to press the constant speed gear 2 (6) up and down.
This can result in measurement errors.

19

If there is any deviation, correct using appropriate shim (8) and repeat measuring procedure.

 The objective is to have an axial play at the lowest tolerance limit.
