Detailed description of the invention
With reference to Fig. 1-Fig. 3, embodiment for the frock of unloading power anti-rotation in this utility model is described further.
It is used for rotating class wheel body as it is shown in figure 1, the present embodiment is one, installs and tighten spacing fixing self-unloading during fixing bolt
The device of power, more specifically, is a kind of for the spacing anti-rotation self-dischanging force device to electric tightening VVT bolt of timing gear.
This device includes keyset 1, internal-gear type position-arresting disk 2 and fixed support 3, in the inner ring of above-mentioned internal-gear type position-arresting disk is provided with
Tooth, internal tooth is meshed with the tooth being screwed on bearing up pulley, plays above-mentioned position-arresting disk and the effect being screwed bearing up pulley and carrying out locking, at this
Having 5 step bolts hole 21 on the circumference of internal-gear type position-arresting disk, keyset 1 is the most disc-shaped, and is arranged concentrically on above-mentioned
The lower section of internal-gear type position-arresting disk, offers 5 installing hole (not shown)s thereon, and each installing hole is all correspondingly arranged at
The underface of one step bolt hole 21, every a pair installing hole and step bolt hole 21 are all equipped with one first
Bolt 4, for internal-gear type position-arresting disk and keyset being fixed together, the first bolt is preferably hexagon socket head cap screw, the head of bolt
Portion is embedded in step bolt hole and installing hole, thus avoids treating in use and tightens part and cause and collide with, scratches part
Surface.
Central authorities at keyset offer a diameter and are about the centre bore 11 of 30mm, the spiral shell to be tightened being screwed on bearing up pulley
Bolt 5 is positioned at the underface of described centre bore, and bolt head diameter to be tighted a bolt is less than 30mm.Keyset is the four of centre bore
It is machined with hole 12, four first location, a diameter of 9mm in the first hole, location week.
Fixed support 3 in the present embodiment is made by steel plate bending, and as shown in Figures 2 and 3, this fixes concrete shape
Support include orthogonal transverse slat 31 and side plate 32, transverse slat and side plate to be that monoblock steel plate is one-body molded make.Side plate reclines
