Abstract
The utility model relates to coupler structure, in particular to a spherical roller coupler used for a winding drum used in crane industry. The spherical roller coupler comprises a half coupler and anouter sleeve sleeved at the outer periphery of the half coupler, the boundary line of the half coupler and the outer sleeve is distributed with a plurality of through holes, a spherical roller passesthrough the through hole, the front end and the back end of the through hole are respectively provided with a pressing ring which is fixed at the half coupler, the external diameter dimension of thepressing ring only can shade one part of the through hole, the outer sides of the two pressing rings are respectively provided with end covers which are connected with the end surface of the outer sleeve, the inner side of the end cover is provided with a concave cavity which is communicated with through hole. The spherical roller coupler used for the winding drum has stable running, low noise, less wearing, long service-life, and convenient installing and adjusting.
Description
Technical field
The utility model relates to a kind of coupler structure, specifically is a kind of reel that is used for lifting industry spherical roller coupling.
Background technique
Existing spherical roller coupling is normally as the disclosed structure of standard JB/T 7009-93 (as shown in Figure 1), it comprises half-coupling 11 with interior mounting hole and the overcoat with adpting flange 12 that is enclosed within the half-coupling periphery, a plurality of through holes 13 distribute on the boundary line of half-coupling and overcoat, in through hole, penetrate spherical roller 14, the through hole two ends are by end cap 15 sealings of annular, and the gap before and after the spherical roller constitutes oil storage chamber.When the coupling of this structure is used for the lifting mechanism of crane gear reel, because the particularity of its load-carrying and safety has outstanding more requirement to its usability.And the spherical roller coupling of existing structure has the following disadvantages:
1, the state fully freely that axially is in of spherical roller in use can produce bigger axial float, makes the stressed not in same plane of each roller, is easy to generate vibration;
2, the oil storage chamber before and after the spherical roller is too little, is not easy to store oil, has strengthened the difficulty of safeguarding, has quickened the wearing and tearing of coupling, has reduced the working life of coupling;
3, nose balance is less.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of stable, noise is little, wearing and tearing less, long service life, installation and reel easy to adjust spherical roller coupling.
Spherical roller coupling of the present utility model comprises the overcoat that has half-coupling and be enclosed within the half-coupling periphery, a plurality of through holes distribute on the boundary line of half-coupling and overcoat, in through hole, penetrate spherical roller, the forward and backward existing two ends of through hole respectively are provided with a pressure ring that is fixed on the half-coupling, the outside dimension of pressure ring makes it only can shelter from the part of through hole, the outside of two pressure rings is respectively arranged with the end cap that is connected on the overcoat end face, and the inboard of end cap is provided with the cavity that communicates with above-mentioned through hole.
Described pressure ring is by being stuck in jump ring location and installation on the half-coupling outer wall on half-coupling.
The utility model is compared with conventional construction, has increased the pressure ring that can carry out axial limiting to spherical roller, has limited the axially large-scale play of spherical roller, has guaranteed the suffered power of each spherical roller in same plane, has guaranteed the steady of operation; Because the end cap inboard is provided with cavity, form the bigger oil storage chamber in space, be convenient to store a large amount of lubricant oil, it is lubricated fully to guarantee that spherical roller obtains, and has reduced wearing and tearing and noise, has prolonged working life; Because internal cavities increases, and makes the coupling axial adjustment more flexible, be convenient to install and adjust.
Description of drawings
Fig. 1 is the structural representation of existing structure spherical roller coupling;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, this spherical roller coupling comprises half-coupling 21 with interior mounting hole and the overcoat with adpting flange 22 that is enclosed within the half-coupling periphery, a plurality of through holes 23 distribute on the boundary line of half-coupling and overcoat, in through hole, penetrate spherical roller 24, before the through hole 23, back two ends respectively are provided with a pressure ring 26 that is fixed on the half-coupling, the outside dimension of pressure ring makes it only can shelter from the part of through hole, form semi-enclosed structure, the outside of two pressure rings is respectively arranged with the end cap 25 that is connected on overcoat 22 end faces, the inboard of end cap is provided with the cavity 251 that communicates with semi-enclosed through hole 23, as oil storage chamber.Pressure ring 26 is by being stuck in jump ring 27 location and installation on the half-coupling outer wall on half-coupling 21.
Claims (2)
1, a kind of reel spherical roller coupling, include half-coupling (21) and be enclosed within the overcoat (22) of half-coupling periphery, a plurality of through holes (23) distribute on the boundary line of half-coupling and overcoat, in through hole, penetrate spherical roller (24), it is characterized in that: before the through hole (23), back two ends respectively are provided with a pressure ring (26) that is fixed on the half-coupling, the outside dimension of pressure ring makes it only can shelter from the part of through hole, form semi-enclosed structure, the outside of two pressure rings is respectively arranged with the end cap (25) that is connected on overcoat (22) end face, and the inboard of end cap is provided with the cavity (251) that communicates with semi-enclosed through hole (23).
2, reel according to claim 1 spherical roller coupling is characterized in that: pressure ring (26) is by being stuck in jump ring (27) location and installation on the half-coupling outer wall on half-coupling (21).
