ギア数と頭の大きさ　いろんなラチェットあるけれどどんなラチェットが作業性が良いのだろ？

Number of gears and head size: There are various ratchets, but which ratchet has the best workability? in a narrow place How many times should I drop the ratchet? Does the screw turn once? A ratchet with a small number of full cycles Isn't it easy to work with? I hypothesized that We tried to compared Ko-ken 3/8”-9.5 Z-EAL Ratchet handle 3725Z 72 gear and 36 gear The size and shape of the head are the same Is it better to have more gears? 72 gear head width approximately 28mm 19.7 times 36 gear head width approximately 28mm 18 times Under these conditions, 36 gears are slightly better. I didn't have to do the full number of times. 72 gear has a bit more play due to its structure. Full angle is about 30° 36 gear was just 2 notches, so I think 36 gears are an advantage. If it's about 25 degrees I think 72 gear was advantageous. If there is no limit to the free angle I don't think there is much difference between 72 gear and 36 gear. NEPROS 90 gear NBR390 Head width approximately 30mm 36 gear NBR3UN Head width approx. 28mm Is NBR3UN's neck slightly thinner? 90 gear NBR390 37 times 36 gear NBR3UN 27 times NBR390 can be said to be a representative of big heads. To withstand high torque with 90 gears I think it's gotten bigger. It's huge after all I can't make the most of my precious 90 gears. There are quite a lot of cases Don't compromise on strength! It feels like I like the KTC feel~ (lol)~ If there is no limit to the free angle There is not much difference between old and new 36 gear 2 notches 30°, 3 notches 40° I feel a good balance SPIDER stepless gearless ratchet BZWBX20938 Head width approximately 35.8mm Feed angle 1° or less 10.7 times large round head Gearless! It's amazing that the feed angle is less than 1°. The amazing thing is that there is almost no play. The problem is...there's no clicking sound. It doesn't feel like a ratchet (lol) Idle torque is a little heavy In this case, the round head is advantageous. Good results with a structure that allows full use of the free angle FACOM J.161B 3/8 72 gear head width approximately 30.5mm R.161 1/4 72 gear head width approximately 25mm J.161B 3/8 11.5 times R.161 1/4 9.5 times The popular secret of the popular Facom Although the gears are smooth The advantage of having a round head is also the secret to its popularity. If the head is small, it is advantageous because you can get a better angle of movement. R.161 1/4 is a very convenient ratchet for narrow spaces. High strength with multiple gears, small head makes it easy to spin I think the 161 is a masterpiece. TONE RH3HW 72 gear Head width approximately 27mm RH3CH 72 gear Head width approximately 20mm HAZET 8816HP 90 gear Head width approximately 32.4mm Mr. Hazet who emphasizes strength Mr. Tone who emphasizes compactness Even the same 3/8" is so different. RH3HW Head width approx. 27mm 9.8 times RH3CH Head width approximately 20mm 7.7 times Having a large number of gears is advantageous in narrow spaces. However...72 gear and 90 gear The difference in feed angle is 1°... The amount of play becomes the idle distance. Head size remains the same This tends to result in a difference in the deflection distance. KTC Flex Ratchet Handle BR2F 6.3mm (1/4 inch) 36 gear head width approximately 22mm 14 times Ko-ken Z-EAL Swing ratchet handle 2726Z 6.3mm (1/4 inch) 36 gear head width approximately 20.5mm 12 times in narrow places Rather than a big head with many gears Even if there are fewer gears, it is better to have a smaller head. Ratchet the full number of times It seems like less is enough If you can secure the necessary strength The more gears the better The smaller the head the better It's better to play less The shaft should be thinner In this condition It turned out to be something like this It will change if the conditions change Please use it as a reference only Tone RH3CH 3/8 72 gear 20mm 7.7 times Facom R.161 1/4 72 gear 25mm 9.5 times Tone RH3HW 3/8 72 gear 27mm 9.8 times SPIDER BZWBX20938 3/8 Gearless 35.8mm 10.7 times Facom J.161B 3/8 72 gear 30.5mm 11.5 times Koken 2726Z 1/4 36 gear 22.5mm 12 times KTC BR2F 1/4 flex ratchet handle 36 gear 22mm 14 times Koken 3725Z 3/8 36 gear 28mm 18 times Koken 3725Z 3/8 72 gear 28mm 19.7 times Nepros NBR3UN 3/8 36 gear 29mm 27 times Nepros NBR390 3/8 90 gear 30mm 37 times Motorcycles, computers, DIY etc. I'm mainly playing around with it I don't often have trouble in very small spaces. TONE's RH3CH 3/8 and RH3HW 3/8 I've been using it for a while It's a ratchet that has a very high chance of being picked up. If you use it like this Maybe it's the best balanc
