Description

Structure at slabber sawing certain applications pairing angular contact ball bearing

Technical field

The present invention relates to a kind of slabber technology, particularly relate to the slabber sawing split bearing configuring technical of cutting wood-based plate and second veneer.

Background technology

Slabber is one of Important Auxiliary equipment on wood-based plate and the second veneer production line, and the sheet material that its effect will suppress or paste face exactly cuts by certain specification.Sawing partly is the core of slabber, and the quality of its structural design directly has influence on the sawing quality and the qualification rate of production board.In sawing split bearing configuration in the past, bearings at both ends all adopts deep groove ball bearing in the bearing block, because the end-play of intrinsic be about in deep groove ball bearing inside 0.18mm～0.30mm, make that the saw blade of rotation produces axial float when sawing sheet material at a high speed, cause the edges of boards after the sawing corrugated lines to occur, collapse angle and the burnt phenomenon of sticking with paste, had a strong impact on the presentation quality and the product percent of pass of production board.

Summary of the invention

In order to overcome the deficiencies in the prior art, must solve saw blade axial float problem, this is to improve the presentation quality of production board and the key of product percent of pass, and it also is purpose of the present invention that a kind of technology at slabber sawing certain applications pairing angular contact ball bearing is provided.Technical scheme of the present invention is by the bearing in the reasonable disposition slabber sawing part, select for use the bearing of very little end-play to achieve the goal, the present invention comes the specific implementation technical scheme by following technical measures: a kind of method and technology at slabber sawing certain applications pairing angular contact ball bearing, comprise bolt, back-up ring, belt wheel, saturating bonnet bolt, spacer, left bearing, bearing block, main shaft, oil scraper ring, right saturating lid, saw blade, clamp nut, outer plate, in pressing plate, flat key, pad, right bearing, the sawing part that saturating lid in a left side and belt wheel flat key are formed is characterized in that:

1) the bearing configuration of described sawing part adopts the supporting of fix-moving about, and the end left bearing that moves about is selected deep groove ball bearing for use; The stiff end right bearing is selected the pairing angular contact ball bearing for use, select for use reason be utilize its only little end-play (0.022～0.03mm), solve saw blade axial float problem, reach the presentation quality that improves production board and the purpose of product percent of pass;

2) described outer plate, saw blade and in the clamp nut of pressing plate by spindle nose closely compress, the thread rotary orientation of clamp nut is opposite with the saw blade direction of rotation, in the saw blade sawing process, clamp nut is locked naturally, and revolves tighter and tighter, and is safe and reliable:

3) oil scraper ring in the described bearing block is installed between the main shaft shaft shoulder and the right bearing, adopts the Q235A material to make, and is the sealing of thread groove form.

Good effect of the present invention is: by the application of pairing angular contact ball bearing on slabber sawing part, effectively solved saw blade axial float problem, the corrugated lines occurs, collapse problems such as angle and burnt paste phenomenon thereby solved the edges of boards that the coping saw blade axial float caused, improved the presentation quality and the product percent of pass of production board greatly.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples:

Embodiments of the invention are wood-based plate slabbers that the pairing angular contact ball bearing is installed in sawing split bearing stiff end, and its sawing part is formed (seeing accompanying drawing) by bolt 101, back-up ring 102, belt wheel 103, saturating bonnet bolt 104, spacer 105, left bearing 106, bearing block 107, main shaft 108, oil scraper ring 109, right saturating lid 110, saw blade 111, clamp nut 112, outer plate 113, lining pressing plate 114, flat key 115, pad 116, right bearing 117, the saturating lid 118 in a left side and belt wheel flat key 119.Require to assemble according to diagram, wherein: the material of main shaft 108 is 45# steel, modifier treatment, and hardness is HB240～280, and the left end diameter of axle of main shaft 108 is φ 25mm, and the right-hand member diameter of axle is φ 35mm; The material of bearing block 107 is that 20# steel, endoporus are stairstepping, and bearing is installed at two ends in the hole: it is the SKF6305-2RS1 deep groove ball bearing that the left bearing 106 of the end that moves about is selected model for use; It is SKF7207BECBP pairing angular contact ball bearing that the right bearing 117 of stiff end is selected model for use; Saturating lid 118 each the saturating bonnet bolt 104 with four M8 * 25 in a right saturating lid 110 and a left side are installed in the outside, bearing block 107 two ends, and adjust the gap of right bearing with pad 116; The material of oil scraper ring 109 is Q235A, adopts the sealing of thread groove form; Plate-like, pressing plate 114 and outer plate 113 and middle saw blade 111 are compressed by clamp nut 112 in the 45# steel is made, the thread rotary orientation of clamp nut 112 is opposite with the saw blade direction of rotation, reaches nature locking, makes slabber security of operation, reliably.
