Description
Technical field
The present invention relates to a kind of bearing that is specifically designed to the dismounting bearing and draw horse, refer more particularly to a kind of screw bearing and draw horse.
Background technology
Draw horse to be also referred to as thruster, be widely used in dismantling axles such as various shaft couplings, gear, bearing, belt pulley and go up fastenings.By its pushing tow mode, be divided into screw usually and draw horse and jack type to draw horse.Present screw draws horse; Its structure comprises: thrust beam be located in the pushing tow screw rod in the thrust beam through screw thread and be movably hinged (or fixed connection) one group of hook (two pawl formula or three-pawl type) together with thrust beam; The top of pushing tow screw rod is provided with rotary drive mechanism, and the bottom of pushing tow screw rod is provided with the pushing tow head.When using this general screw to draw Malaysia dismounting bearing; If the position of hook and thrust beam is improper; The clamping part of hook will with the outer ring of bearing between form line and contact, the cross section shape that receives force direction and bearing of bearing in an angle, thereby to spool carrying out in the process of pushing tow in the bearing; Cause bearing deformation, influence the normal use of bearing.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of can be so that the outer ring formation face contact of the clamping part of hook and bearing and the consistent screw bearing of the cross section that receives force direction and bearing of bearing draw horse.
For solving above-mentioned technical problem; The technical scheme that the present invention adopted is: a kind of screw bearing draws horse; Comprise: thrust beam, pushing tow screw rod and a pair of hook; The central authorities of thrust beam are provided with the pushing tow screwed hole that matches with the pushing tow screw rod, and the top of pushing tow screw rod is provided with rotary drive mechanism, and the bottom of pushing tow screw rod is provided with the pushing tow head; The top of said hook offers the locating hole that matches with thrust beam; The clamping part of the bottom of hook for matching with the outer ring of bearing, one of them hook is offering a pair of locking through hole that is parallel to each other near nip, and another hook is offering a pair of locking screw pit that is parallel to each other near nip.
Described hook is being respectively arranged with jut near its nip to both sides, and the jut of both sides forms installation portion with the connecting portion that is connected two side projecture parts, and described locking through hole and locking screw pit are arranged on the installation portion of corresponding hook.
Described rotary drive mechanism comprises: be arranged on the driving cap at pushing tow screw rod top, drive on the cap and offer the whippletree through hole that is used to wear whippletree, be equipped with whippletree in the whippletree through hole.
The invention has the beneficial effects as follows:, make the clamping part of hook contact with bearing maintenance face all the time, thereby the cross section that receives force direction and bearing that has guaranteed bearing is consistent because hook can translation on thrust beam; And; Through two clamping screws a pair of hook is tightened up on the outer ring of bearing, the pushing tow screw rod makes the stressed balanced more of bearing between two clamping screws; Thereby guaranteed that bearing can not be out of shape in the process of the axle in the pushing tow bearing.In addition; Hook is respectively arranged with jut near its nip to both sides at hook; Thereby can use this jut and offer locking through hole or locking screw pit; So just can be so that the body of hook is narrow, not only make and wholely draw horse lighter, but also reduced material cost.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1; Screw bearing of the present invention draws horse, comprising: thrust beam 1, hook 3 and 4, be located in the pushing tow screw rod 2 in the thrust beam 1 through screw thread, the central authorities of thrust beam 1 are provided with the pushing tow screwed hole that matches with pushing tow screw rod 2; The top of pushing tow screw rod 2 is provided with rotary drive mechanism; Its concrete structure comprises: be arranged on the driving cap 21 at pushing tow screw rod 2 tops, drive on the cap 21 and offer the whippletree through hole that is used to wear whippletree 6, be equipped with whippletree 6 in the whippletree through hole; The bottom of pushing tow screw rod 2 is provided with pushing tow head 22, and the top of said hook 3 offers the locating hole that matches with a side of thrust beam 1, and the top of said hook 4 offers the locating hole that matches with the opposite side of thrust beam 1; Here; The geomery of thrust beam 1 both sides is the same, and therefore, hook 3 and 4 can be set in any side of thrust beam 1 with exchanging; The clamping part 32 and 42 of the bottom of hook 3,4 for matching with the outer ring of bearing; One of them hook 3 is offering a pair of locking through hole that is parallel to each other near clamping part 32 places, another hook 4 is offering a pair of locking screw pit that is parallel to each other near clamping part 42 places, and; The central lines of corresponding locking through hole and locking screw pit; These two center lines are in a plane, and are and vertical with the center line of pushing tow screw rod 2, and a pair of clamping screw 5 passes two locking through holes of hook 3 one sides respectively; Be located in through screw thread in the corresponding locking screw pit of hook 4 one sides, described pushing tow screw rod 2 passes between this a pair of clamping screw 5.In the present embodiment; Described hook 3 is being respectively arranged with jut 31 near its clamping part 32 places to both sides; The jut 31 of both sides forms locking through hole installation portion with the connecting portion that is connected two side projecture parts 31; Described locking through hole is opened on the locking through hole installation portion; Described hook 4 is being respectively arranged with jut 41 near its nip 42 to both sides, and the jut 41 of both sides forms locking screw pit installation portion with the connecting portion that is connected two side projecture parts 41, and described locking screw pit is opened on the locking screw pit installation portion; During actual fabrication, a pair of locking through hole is opened in respectively on two juts 31 of hook 3, and a pair of locking screw pit is opened in respectively on two juts 41 of hook 4; Such structure; Can reduce the width of hook 3 and 4 bodies, alleviate and draw horse weight, reduce material cost.
During actual the use,, make hook 3 contact with the outer ring maintenance face of bearing all the time with 42 with 4 clamping part 32 with hook 3 and 4 translations on thrust beam 1; Then; Through a pair of clamping screw 5 hook 3 and 4 is tightened up on the outer ring of bearing,, make the stressed balanced more of bearing because pushing tow screw rod 2 is between these two clamping screws 5; Thereby guaranteed that bearing can not be out of shape in the process of the axle in the pushing tow bearing.
