Abstract
The utility model relates to a novel crosshead shoe structure of a slide block type universal spindle, which can efficiently solve the problem of metal engagement on a sliding plane, greatly prolong the service life of a universal shaft, and save manufacturing cost. The crosshead shoe structure comprises a crosshead shoe and is characterized in that holes are formed on four working faces of the crosshead shoe; and antifriction pieces are embedded n the holes.
Description
(1) technical field
The utility model relates to the application of antifriction material, is specially a kind of novel slide block type universal-joint spindle crosshead shoe.
(2) background technique
Because crosshead shoe universal-joint spindle physical dimension compactness, transmitting torque is big, also can be used for the occasion in different axle center, so the occasion that extensively should need be changed in the transmission center.If but just there is sliding friction pair in the words in slider typed universal joint spindle different axle center of connected two rotors in driving torque, this sliding friction pair produces the phenomenon of working surface metal interlock easily under the bad situation of lubricating condition, thereby reduces transmission efficiency.
(3) model utility content
At the problems referred to above, the utility model provides a kind of novel slide block type universal-joint spindle crosshead shoe, and the interlock problem that it can effectively solve the slip surface metal has prolonged working life of cardan shaft greatly, has saved cost of production.
Its technological scheme is such: it comprises crosshead shoe, it is characterized in that: perforate on four working surfaces of described crosshead shoe, described hole is embedded in the antifriction sheet.
It is further characterized in that: described antifriction sheet is made by teflon.
The utility model structure crosshead shoe, it has adopted the teflon with good lubrication performance, thereby has reduced sliding friction pair, also just reduce slip surface metal scuffing, guaranteed transmission efficiency, improved the working life of cardan shaft, reduce corrective maintenance time, save production cost.
(4) description of drawings
Fig. 1 is the utility model crosshead shoe master TV structure schematic representation;
Fig. 2 is the utility model crosshead shoe plan structure schematic representation;
Fig. 3 is the slider typed universal joint spindle erection drawing.
(5) embodiment
See Fig. 1, Fig. 2, four working surfaces of crosshead shoe described in the utility model 3 evenly bore the hole 8 of respective numbers, hole 8 dark 5mm, diameter 15mm, and hole 8 is embedded in antifriction sheet 9, antifriction sheet 9 is lathed the disk of the thick diameter 15mm of 5.2mm by polytetrafluoroethylsteel steel bar, and raps in the hand-hole 8 with wooden mallet.
Slider typed universal joint spindle assembly process once is described below: a left side connects cover 1 and is connected with crosshead shoe 3, connecting pin 2 is as middle turning joint, indirect axle 5 two ends are connected with crosshead shoe 6 with cross sliding 3 respectively, connecting pin 4 is as middle hinge, crosshead shoe 6 and the right side connect cover 7 catenation principles and a crosshead shoe 3 and a left side connect overlap be connected identical.Assembling back transferring power is passed to crosshead shoe 6 from right joint-shaft 7 inputs, and crosshead shoe 6 is passed to indirect axle 5 again, and the indirect axle is passed to crosshead shoe 3 again, and crosshead shoe 3 is passed to a left side again and connect cover 1, finishes the transmission of moment of torsion.
If a left side connects cover 1 and connects cover 7 not on same axis with the right side, connecing cover when cardan shaft rotates so just is rotation angle in center with the middle hinge with slide block, crosshead shoe this moment four working surface A, B, C, D just have relative sliding phenomenon, because A, B, C, D working surface have had antifriction material, the friction factor of slide relative is half when not having antifriction material, frictional force with regard to little half, significantly reduced the interlock chance of A, B, C, D working surface, definitely transmission efficiency, also reduced corrective maintenance time.
Claims (2)
1, a kind of crosshead shoe structure of novel slide block type universal-joint spindle, it comprises crosshead shoe, it is characterized in that: perforate on four working surfaces of described crosshead shoe, described hole is embedded in the antifriction sheet.
2, the crosshead shoe structure of a kind of novel slide block type universal-joint spindle according to claim 1 is characterized in that: described antifriction sheet is made by teflon.
