Abstract
The utility model relates to a roller assembly with an integrated inner ring and for an elevator. An inner ring and a step shaft of the existing roller assembly are required to be machined respectively, and the machining is complex in procedure and time-consuming and wastes materials. The roller assembly comprises an outer ring, balls and the integrated inner ring. The large-diameter section on one side of the inner ring is matched with the outer ring to clamp the balls, and the small-diameter section on the other side forms a support connection portion. The bearing inner ring and the step shaft which are machined and installed in a split mode originally are changed to be machined simultaneously to form the integrated inner ring, the steps of single machining and installation of the step shaft are omitted to simplify the installation procedures, and the machining efficiency is further improved. In addition, due to the fact that the integrated inner ring is adopted, use quantity of raw materials is further reduced while structure strength is ensured.
Description
Technical field
The utility model relates to a kind of lift facility, is specifically related to a kind of roll wheel assembly.
Background technology
Door strap is one of critical component in the door system of vertical lift elevator, and is installed on roll wheel assembly on door strap its crucial subassembly especially.The roll wheel assembly using on existing door strap, generally, roll wheel assembly comprises bearing, is plugged on the Step Shaft in bearing, and in use, described bearing is generally deep groove ball bearing, comprises outer shroud, interior ring and is clamped in movably the ball in inner and outer ring.Bearing is realized with door strap and being connected by Step Shaft, and door strap is moved by roll wheel assembly.There is following defect in the roll wheel assembly of this structure: 1,, because Step Shaft needs processing separately, refill and be fitted in bearing, cause technological process relatively long, and when processing respectively each parts the more raw MAT'L of loss, workpiece work efficiency is low; When 2, Step Shaft and bearing are riveted assembling by pressure, have certain risk equipped not in place, and certainly exist accumulation Mismachining tolerance, while making roll wheel assembly real work, there is larger right alignment, run-out error in bearing.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of elevator roll wheel assembly with ring in integral type, bearing inner ring and Step Shaft is united two into one to reduce Mismachining tolerance, and save raw MAT'L.
The utility model is realized by following steps: a kind of elevator roll wheel assembly with ring in integral type, the ball that comprises outer shroud, is positioned at outer shroud inner side and distributes ringwise, described roll wheel assembly also comprises that one is ring in the columned integral type of reducing, the described interior ring one large footpath of side section is mated the described ball of clamping with described outer shroud, opposite side path section forms support and connection portion.The bearing inner ring that original separate machined is installed and Step Shaft are improved in the integral type being simultaneously processed to form and encircle, by saving the step of independent processing, installation step axle, simplify installation procedure, and then raising work efficiency, in addition, owing to adopting in integral type, encircle, when guaranteeing structural strength, also reduced raw-material use amount; Because bearing inner ring and Step Shaft are merged in integral type and encircled, thereby effectively avoid causing both to occur coaxiality error and run-out error because both process the accumulative total Mismachining tolerance occurring in installation process; Adopt after the interior ring of integral type, without independent processing step axle, effectively reduce its waste of raw materials amount in turning, grinding process; Described roll wheel assembly is planted and is fixed on door strap by the path section of encircling in integral type, and door strap is supported on described roll wheel assembly, and roll wheel assembly auxiliary door link plate moves.
As preferably, on the outside face of the large footpath of described interior ring section and described outer shroud madial wall, all have the chute with described ball outline, described outer shroud and interior ring are respectively by the described ball of chute coupling clamping on it.Chute had both played the effect of clamping holding ball, also played the effect of guiding ball moving, and guaranteed that interior ring, outer shroud and ball have larger area of contact, the application force that effectively disperses ball to bear.
As preferably, lightening hole is all offered at the two ends of described interior ring.By offering lightening hole, reduce the weight of encircling in integral type, in the situation that guaranteeing its structural strength, guarantee the movable alerting ability of interior ring.
As preferably, the large footpath section of described interior ring is connected with the intersegmental step surface that passes through of path, between described step surface edge and described ball, is provided with preset clearance.Interior ring is planted on the parts that are fixed on door strap or are connected with door strap by its path section, door strap or the parts that are connected with door strap form installation portion, installation portion is nested with in the path section of interior ring, and conflict on described step surface, guarantee installation portion and outer shroud preset clearance, while preventing that outer shroud from rotating and installation portion rub.
As preferably, the lateral wall of described outer shroud is provided with annular groove, and described annular groove bottom is provided with the vibration damping layer of polyurethane material.The vibration damping layer of annular groove bottom contacts with door strap, effectively reduces the vibration and the consequent noise that when both contact, produce.
The beneficial effects of the utility model: the bearing inner ring that original separate machined is installed and Step Shaft are improved in the integral type being simultaneously processed to form and encircle, by saving the step of independent processing, installation step axle, simplify installation procedure, and then raising work efficiency, effectively avoid causing both to occur coaxiality error and run-out error because both process the accumulative total Mismachining tolerance occurring in installation process, effectively reduce its waste of raw materials amount in turning, grinding process.
