Worked Solution & Example Answer:5.1 FIGUUR 5.1 hieronder toon 'n skroeFFraadrwysersplaat wat op 'n draaibank voorkom - English General - NSC Mechanical Technology Fitting and Machining - Question 5 - 2023 - Paper 1

Step 1

5.1 Benome die dele A-C.

96%

114 rated

Answer

A. Leiskroef
B. Wysplaat
C. Wurmwiel / wurmrat

Step 2

5.2.1 Die lengte van die taps

99%

104 rated

Answer

Gebruik die volgende formule:
$L = \frac{D - d}{2 \cdot \tan(\frac{\theta}{2})}$
Hier is $heta = 11°$ , $D = 65$ mm, en $d = 45$ mm.
Substitueer die waarde in die formule: $L = \frac{65 - 45}{2 \cdot \tan(5,5°)}$
Dus, $L = 103,85$ mm.

Step 3

5.2.2 Die oorstelling van die loskop wat vereis word om die taps te sny

101 rated

Answer

Gebruik die volgende formule:
$x = \frac{L(D - d)}{2}$
Hier kan ons $L$ insit wat ons pas bereken het ( $L = 103,85$ mm): $x = \frac{103,85(65 - 45)}{2}$
Gevolglik, $x = 10$ mm.

Step 4

5.3.1 Wydte

98%

120 rated

Answer

Gebruik die formule: $Wydte = \frac{D}{4} = \frac{70}{4} = 17,50 \text{ mm}$

Step 5

5.3.2 Dikte

97%

117 rated

Answer

Gebruik die formule: $Dikte = \frac{D}{6} = \frac{70}{6} = 11,67 \text{ mm}$

Step 6

5.3.3 Lengte

97%

121 rated

Answer

Gebruik die berekening: $Lengte = 1,5 \times \text{diameter van as} = 1,5 \times 70 = 105 \text{ mm}$

Step 7

5.4 Bereken die gemiddelde diameter

96%

114 rated

Answer

Gebruik die formule: $Gemiddelde\,Diameter = OD - (\frac{1}{2} \times P)$
Hier is $OD = 38 - 2 = 36$ mm.
