The fastening grooves being mutually adapted that the part of cover plate carries out being stamped and formed out is fastenedly connected with fastening projection, described fastening grooves
Cell wall on be evenly equipped with several spacing sulculuses, described fastening projection is provided with spacing sulculus interference fit is spacing little convex
Rise, described base is provided with cambered surface rope approaching channel, on the notch of described cambered surface rope approaching channel relative to trough wall surface on symmetry set
It is equipped with the spacing preiection preventing rope from deviating from, in the groove of described cambered surface rope approaching channel, is covered with one layer of mute layer.
As preferably, described fastening grooves and fastening projection are circular trough and circular protrusions.
As preferably, the bottom land bore of described fastening grooves is more than notch footpath, the top outer bore that described fastening is protruding
More than bore outside root.
As preferably, described spacing preiection is provided with by root to end gradually towards the side outside cambered surface rope approaching channel groove
The rope approaching face that direction tilts in cambered surface rope approaching channel groove.
As preferably, described spacing preiection be provided with towards the side in cambered surface rope approaching channel groove by root to end by
The confined planes that gradually direction tilts in cambered surface rope approaching channel groove.
As preferably, the sidewall of described bearing outer ring is provided with locating slot, described base and cover plate are provided with embedding
Locating piece in locating slot.Said structure is not only beneficial to bearing location, and also ensures that bearing is connected more with between base and cover plate
Add firm.
As preferably, described locating slot is several that be arranged on bearing outer ring discontinuously.
As preferably, described locating slot is the ring recess arranged with coaxial bearing.
As preferably, described mute layer is nylon layer.
In sum, this utility model has the advantages that
1, the interference fit that the application is formed with cover plate by base so that both link together, arranges limit simultaneously again
Position sulculus and spacing little projection are to ensure more to stablize between base and cover plate, be firmly combined together, thus have reached nothing
The effect of rivet, and enhance the bonding strength of base plate and cover plate, decrease production process.
2, the application is also provided with spacing preiection so that even if there is relaxation cases, and rope also will not be easily from rope sheave
Abjection in the cambered surface rope approaching channel of main body, and rope the most easily pacifies in cambered surface rope approaching channel, effectively improve elevator rope pulley with
Elevator rope cooperation steadiness between the two.Nylon material specifically good performance muffler, the setting of nylon layer makes this reality
The noise produced when using in elevator landing door system by the Elevator roller of novel middle offer is little.
3, the application simple in construction, easy to process, low cost, noise are little, stability in use is good, uses safer.
