In use, by positive stop strip 33 and being embedded into limiting slot 34, this makes it possible to play a positioning work
With the installation process of entire first mounting plate 28 has a guiding role, prevents it from shifting during the installation process.
By the way that the second mounting groove 36 is arranged on sliding shoe 4, second mounting plate 37, ball rack are installed in the second mounting groove 36
Ball 35 in 38 exposes from through-hole 40, is contacted with idler wheel 26, and material is thus formed a bidirectional rolling frictions, simultaneously
If idler wheel 26 leans on too close in use, rotation axis 30 is easy to shift, and leads to card wheel, therefore idler wheel 26 is suitble to set
It sets in outer diameter, and ball 35 will not then fail because of lean on too close, if ball 35 is apart from too far instead, transmission work can not had
With, therefore ball 35 is arranged on sliding shoe 4, ball 35 and 35 point of ball can be enabled to play effective transmission in this way,
Especially the spacing of ball 35 and ball 35 is arranged to for single idler wheel 26 being embedded between the gap of two balls 35, in this way
It can play the effect of a pre-determined bit, the stabilization of scale of guarantee, meanwhile, it is further reduced coefficient of friction, ensure that
Its service life.
During installation, it is only necessary to by the mounting hole 42 and the second mounting plate 37 in the fixed plate 41 on ball rack 38
The alignment of three threaded holes 43, the installation and fixation of ball rack 38 can be realized by being screwed into bolt, and this mounting means, structure is simple,
Easily operated and processing.
By in use, being provided with the groove 44 for being embedded in ball 35 on idler wheel 26, this makes it possible to make
During relative displacement, idler wheel 26 and ball 35 mutually play a position-limiting action, ensure that sliding shoe 4 will not occur partially
It moves.
