本考案はネガティブディスクブレーキの隙間調整装置の
改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a clearance adjustment device for a negative disc brake.
一般に、クレーン等の機械装置に用いられることの多い
ネガティブブレーキ装置については、装置が比較的大型
となることが多いことなどから所謂キャリパフローティ
ングタイプのディスクブレーキを用いる例が増している
。In general, negative brake devices that are often used in mechanical devices such as cranes are often relatively large, so so-called caliper floating type disc brakes are increasingly being used.
そしてこのようなネガティブディスクブレーキにおける
摩擦パッドのライニング摩耗に伴う作動遅れ、作動液量

手動操作によってディスク軸方向に出入しうる調整ボル
トを螺着し、この調整ボルトをアウター側摩擦パッドの
押圧体として用いるようにした簡単構造のものが提供さ
れている。In order to prevent delay in operation and increase in the amount of hydraulic fluid due to friction pad lining wear in negative disc brakes, the clearance adjustment device is designed to avoid complicating the structure of the negative brake operating mechanism. Therefore, a simple structure is provided in which an adjustment bolt that can be moved in and out in the disk axial direction by manual operation is screwed onto the reaction part side of the floating caliper, and this adjustment bolt is used as a pressing body for the outer side friction pad. ing.

該調整ボルト９の回り止めをなすストッパである。Figures 1 to 3 show such a negative disc brake, in which 1 is a disc, 2 is a fixed support, and 3 is a negative disc brake.
1 is a caliper, 4 and 5 are slide pin type caliper sliding support mechanisms, 6 and 7 are a pair of opposing friction pads, and 8 is a negative type brake actuation mechanism housed in one leg 3a on the inner side of the caliper 3. , 9 is an adjustment bolt screwed onto the other leg 3b on the outer side of the caliper 3 so as to be able to move in and out in the disk axial direction, and 10 is attached to the reaction part of the caliper 3 and is engaged with the gear 9a of the adjustment bolt 9. This is a stopper that prevents the adjustment bolt 9 from rotating when fitted together.
そして、通常は作動バネのバネ力によってピストン８ａ

圧作用によりピストン８ａが作動バネを圧縮するとブレ
−キカを解除するように構成されている。Normally, the piston 8a is moved by the spring force of the operating spring.
When the inner side friction pad 6 is pressed against the disc 1, this reaction force acts on the caliper 3 to move it to the right in the figure, and the adjustment bolt 9 of the reaction part pushes the outer side friction pad 7 against the disc 1. These contradictory presses apply hydraulic pressure to the disc 1 to obtain a braking force, and when the piston 8a compresses the operating spring due to the hydraulic action, the brake force is released.
隙間調整は、このブレーキ作動機構において調整ボルト
９を適当量図の右方に螺出させることにより行なうもの
である。Gap adjustment is performed by screwing out the adjustment bolt 9 by an appropriate amount to the right in the diagram in this brake operating mechanism.

く虞れがあり、この問題は産業機械装置を港湾地等で使
用するときに特に配慮されねばならない点となっていた
。However, one of the problems with the gap adjustment device for negative disc brakes with the above configuration is that the threaded part is exposed to the outside air, which may cause rust and make adjustment impossible. This is a point that must be especially taken into consideration when industrial machinery is used in ports, etc.

In the negative disc brake, the adjustment bolt is provided with an adjustment bolt that forms a pad pressing body, and a stopper that engages with a gear portion of the adjustment bolt to prevent it from rotating. A cap that seals the threaded portion from the outside air by sliding sliding contact is assembled so as to be non-rotatable, and the adjustment bolt is prevented from rotating by a gear portion formed on the cap and the stopper. This is a gap adjustment device for negative disc brakes.
