Abstract
The utility model provides a three-wedge-claw bearing detaching device, which is characterized in that the bearing plate of the detaching device is provided with a center hole, a pulling lever is arranged in the center hole, a positioning sleeve and a locking nut are screwed at the rear end of the pulling lever; a blocking board and a fastening supported on the cover are arranged at the front end of the pulling lever; a ring shape ''T'' groove is arranged at the front end of the bearing plate; three ''T'' groove bolts are arranged in the ring shape ''T'' groove; three wedge claws are arranged at the front end face of the bearing plate through ''T'' bolts; a ring-shaped sleeve is arranged at the circumference of the center hole at the front end of the bearing plate; a locking bolt which can move the wedge claw into the position between the bearing and the blocking shoulder of the cover is arranged on the ring-shaped sleeve; under the pulling force of the pulling lever, the bearing can be disengaged from the cover, the problem that the bearing is detached from the cover is solved. In addition, the utility model has the advantages of simple structure, easy manufacturing, low cost, convenient operation.
Description
Technical field
The utility model relates to a kind of shaft bearing replacer that is used for the lathe overhaul, especially a kind of three wedge pawl shaft bearing replacers.
Background technology
In lathe assembling and overhaul process, can run into the problem of dismounting bearing.A lot of from the method for axle dismounting bearing, as: with three pull bar stripping attachments, bearing induction heater, withdrawal sleeve, oil pressure method etc.But do not have the special dismounting device at present from housing dismounting bearing, generally only when design and installation, on the shoulder block of housing, set in advance several places otch or eject the screwed hole of screw, so that use during dismounting.Yet, because the restriction of shell structure, bearing on a lot of housings is installed and otch can not be set or be provided for the screwed hole that screw ejects, therefore very difficult from housing dismounting bearing, especially for the lathe of overhaul, through use for many years, very closely (also may produce vacuum phenomenon) that the dead eye inner surface of outer race and housing is fitted so just more can't be dismantled.
Summary of the invention
The utility model provides a kind of three wedge pawl shaft bearing replacers simple in structure, effectively for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Three wedge pawl shaft bearing replacers, comprise that discoidal center has the carrier in hole, uniform three the wedge pawls that have acute angle on the carrier front end face that are installed in, the two ends that are installed in the carrier centre bore have the pull bar of nut and are installed in pull bar upper pulling force baffle plate, it is characterized in that: described carrier front end face is shaped on annular T type groove, three T type grooved screws that the wedge pawl is installed are installed in annular T type groove, be shaped on microscler adjustment hole on the wedge pawl with T type grooved screw coupling, carrier front end centre bore periphery is shaped on ring set, and three jackscrews that promote the reach of wedge pawl are installed on the sidewall of ring set.
The utility model can also adopt following technical measures:
Also be shaped on counterbore on the centre bore of described carrier rear end, assembly has the positioning sleeve that is connected with pull rod screw in the counterbore.
Advantage and the good effect that the utlity model has are: because three wedge pawls that front end has acute angle are installed on the front end face of carrier, in the carrier centre bore, pull bar is installed, the pull bar other end is equipped with the baffle plate that is supported in housing, jackscrew promotion wedge pawl by carrier is wedged bearing face gradually between the housing shoulder block, under the pulling of pull bar, make bearing break away from housing, and do not damage housing and bearing, solved the problem that bearing is dismantled from housing, the utility model also has simple in structure in addition.The advantage of be easy to make, cost is low, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, housing; 2, wedge pawl; 3, nut; 4, carrier; 5, T type grooved screw; 6, jackscrew; 7, positioning disk; 8, nut; 9, pull bar; 10, bearing; 11 baffle plates; 12, nut; 13, annular T type groove; 14, microscler adjustment hole; 15, acute angle; 16, ring set.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, discoidal carrier 4 is shaped on centre bore and counterbore, pull bar 9 is installed in the carrier centre bore, and the rear end screw thread of pull bar is equipped with positioning sleeve 7 and the locking nut 8 that embeds counterbore, and the front end of pull bar is equipped with baffle plate 11 and the clamp nut 12 that is supported in shell ends.The front end of carrier 4 is shaped on annular T type groove 13, and three T type grooved screws 5 and nut 3 thereof are installed in the annular T type groove.At the carrier front end three wedge pawls 2 are installed by T type grooved screw, are shaped on the microscler adjustment hole 14 that mates with T type grooved screw on the wedge pawl, the front end of wedge pawl is shaped on the acute angle 15 between the shoulder block of wedging bearing 10 and housing 1.Carrier front end centre bore periphery is shaped on ring set 16, and three jackscrews 6 that promote each wedge pawl are installed on the sidewall of ring set, by jackscrew the wedge pawl is wedged between bearing and the housing shoulder block like this, under the pulling force effect of pull bar, makes bearing break away from housing.
Claims (2)
