【考案の詳細な説明】
本考案は研削用砥石のスリーブに関するもので
ある。[Detailed Description of the Invention] The present invention relates to a sleeve for a grinding wheel.
本考案の目的は、砥石との嵌合クリアランスを
最小とし、しかも砥石破損の恐れのない砥石スリ
ーブを提供するものである。 An object of the present invention is to provide a grindstone sleeve that minimizes the fitting clearance with the grindstone and is free from the risk of damage to the grindstone.
ビトリフアイド砥石類似物よりなる多孔質セラ
ミツクスの保持体外周面に、ダイヤモンド、立方
晶窒化硼素等の硬質砥粒を合成樹脂結合剤にて結
合した硬質砥粒層を有する研削用砥石は公知であ
る。 A grinding wheel is known that has a hard abrasive layer formed by bonding hard abrasive grains such as diamond or cubic boron nitride with a synthetic resin binder on the outer peripheral surface of a porous ceramic holder made of a vitrified whetstone analogue.
この研削用砥石は高価であり、限られた層厚の
硬質砥粒層を砥石振れを修正するためにドレスす

リアランスを極力小さくし砥石交換時の砥石振れ
を小さくして修正量を極少とすることが望まし
い。 This grinding wheel is expensive, and it is not preferable to dress the hard abrasive grain layer with a limited layer thickness to correct grinding wheel runout. It is desirable to minimize the amount of correction by reducing the runout.
しかし、砥石スリーブとの嵌合クリアランスを
小さくすると、セラミツクスの保持体より砥石ス
リーブ（鉄）の方が熱膨張が大きいため、研削時
の発熱及び油温、室温の上昇によつて砥石スリー
ブの径方向に熱膨張で保持体内周面に引張応力が
発生し、保持体が脆性材料であるため破損する恐
れがあり危険である。 However, if the fitting clearance with the grinding wheel sleeve is made small, the grinding wheel sleeve (iron) has a larger thermal expansion than the ceramic holder, so the heat generation during grinding and the rise in oil temperature and room temperature will cause the diameter of the grinding wheel sleeve to decrease. Tensile stress is generated on the inner circumferential surface of the holding body due to thermal expansion in the direction, and since the holding body is a brittle material, there is a risk of damage, which is dangerous.
本考案はこのような問題を未然に防止するため
に改良した砥石スリーブを提供するものである。
以下本考案の実施例を図面によつて説明する。 The present invention provides an improved grindstone sleeve to prevent such problems.
Embodiments of the present invention will be described below with reference to the drawings.

１との間で砥石６を挟持するものである。 Reference numeral 1 denotes a sleeve body, which has a fitting hole 2 for a grindstone shaft (not shown) and a flange fitting part 3. 4
is a flange that fits into the flange fitting portion 3 and is tightened by bolts 5, and holds the grindstone 6 between it and the sleeve body 1.

た硬質砥粒層８を有している。 The whetstone 6 is a hard abrasive in which hard abrasive grains such as diamond or cubic boron nitride are bonded to the outer peripheral surface of a porous ceramic holder 7 made of a vitrified whetstone analog with a synthetic resin binder or a vitrify binder. It has layer 8.

状体１０の取付ボルトを示す。 In the present invention, the sleeve body 1 is provided with the holder 7.
An annular body 10 into which the inner circumferential surface 9 of the annular body 10 is fitted is provided concentrically and integrally with one end.
A gap is formed between the inner periphery of the annular body 10 and the sleeve body 1. Moreover, the annular body 10 is made of a material with a low thermal expansion coefficient smaller than that of the holder 7, such as a type of invariant steel made of an alloy of iron and nickel.
An annular groove 10a is formed to allow deformation (deformation due to a difference in thermal expansion) between the attachment part to the holding body 7 and the fitting part to the inner circumferential surface 9 of the holder 7. Reference numeral 11 indicates a mounting bolt for the annular body 10.
上記本考案によれば、スリーブ本体１におい
て、砥石６の構成体である保持体７の内周面が嵌
合される部分を保持体７の熱膨張係数より小さい
低熱膨張係数材料による環状体１０を設けたもの
であるから、研削時の発熱および油温、室温が上
昇しても環状体１０は砥石６を破損する熱膨張は
起らない。 According to the present invention, the part of the sleeve body 1 into which the inner circumferential surface of the holder 7, which is a component of the grinding wheel 6, is fitted is formed into an annular body 10 made of a material with a low thermal expansion coefficient smaller than that of the holder 7. Therefore, even if heat generated during grinding, oil temperature, and room temperature rise, thermal expansion that would damage the grindstone 6 does not occur in the annular body 10.
従つて、スリーブ本体と砥石の内周面との嵌合
クリアランスを極小とし、砥石交換時の振れを最
小とすることができ、また、温度上昇による砥石
破損の恐れがない等の効果を有する。 Therefore, the fitting clearance between the sleeve body and the inner circumferential surface of the grinding wheel can be minimized, the vibration when replacing the grinding wheel can be minimized, and there is no risk of damage to the grinding wheel due to temperature rise.
