An engaging device of a linear sliding rail includes a sliding rail and a sliding block. The sliding block comprises a sliding base body, a supporting body and two connecting bodies. The front and rear ends of the sliding base body have a positioning plate respectively. The two locking pieces each comprises hooks. The hook locks the two connecting bodies at the front and rear ends of the sliding base body. The hook abuts against one end of the abutting piece. The other end of the abutting piece abuts against front and rear end faces of the supporting body respectively. Via this arrangement, when the locking piece locks the two connecting bodies at both ends of the sliding base body, it also generating a pre-pressure to press the supporting body, thereby assembling the supporting body and the two connecting bodies on the sliding base body tightly and firmly.

A friction applying apparatus and a linear guide apparatus having the same, according to the present invention can uniformly contact allover contacting faces of sliding members to the contacted members so as to reduce abrasion in the sliding members and the contacted members, and may maintain appropriate frictional force and precision. In the friction applying apparatus forcing the sliding members moving along guide rails for generating friction, the sliding member is made of a material having elastic modulus being 5000 MPa or less and Vickers hardness being 400 or more.

A slide is mounted on a slideway with a pair of tongue and groove interconnections. The slideway has a pair of engagement rails or tongues provided on a pair of cantilevered arms. The rails are spring biased within a pair of grooves formed in the slideway. An adjustment screw drives the arms apart to adjustably spring bias the rails into the grooves.

The linear guide apparatus includes a guide rail 3 including a rolling body rolling groove 8 and a friction apply unit 6 assembled to the guide rail 3. The friction apply unit 6 includes a unit main body 15, a brake member 16, an oil pressure cylinder 17 and a plate spring 32. The brake member 16 is disposed so as to face the side surface 3a of the guide rail 3 and can be contacted with the other portions of the side surface 3a than the rolling body rolling groove 8 thereof. The oil pressure cylinder 17 includes a piston member 20 which is structured to be driven in a positive direction to thereby press the brake member 16 against the side surface 3a of the guide rail 3 and also the piston member 20 can be driven in the opposite direction to thereby remove the pressure of the brake member 16 from the side surface 3a.

A traveler comprises a track with two lateral side grooves and a top surface, and a car slideably held on the track. The car has first and second lateral side portions, with bearing means in each portion for engaging respective of the track side grooves. The car further has thrust bearings removably held in a race in a car center portion for engaging the track top surface when the car may be tilted towards one or the other lateral sides, as may occur when the car is under a load from that lateral side.

A slider slidably mounted on a guide rail has a recess formed in the lower surface of the slider, and a pressure vessel made of elastic material is accommodated in the recess. A friction plate is attached to the lower surface of the pressure vessel to abut against the upper surface of the guide rail. Hydraulic pressure is exerted on the upper surface of the guide rail through the friction plate by the pressure vessel and is adjustable by a pressure control valve so as to vary the frictional resistance between the slider and the guide rail.

A clamping device for a sliding mount, particularly a dove-tail mount, in which a guide projecting from a slide clock is slidably mounted in a guide groove of a guide body. The clamping device includes a slot in the guide body extending parallel to the guide groove and defining a clamping part between the slot and the groove which can be pressed against the guide. A cavity, in which a bolt is located, is provided in the guide body such that the upper end of the bolt is within the unslotted part of the guide body and the lower end of the bolt is adjacent said clamping part. A clamping screw extends within a threaded bore in the body and is arranged to displace the bolt such that the lower end of the bolt presses against the clamping part whereby the slide block is clamped relative to the groove.
