Abstract
The utility model relates to an automatic centering support roll, which comprises a spring, a spring pocket, a connective filament axis with a lug boss, a sealed bearing box, and an arc-shaped supporting frame. The filament axis connected with the spring pocket is pinned through a locking bolt, and the filament axis can not be loosened through forward rotation and backward rotation. Because a cone-shaped bearing is sheathed on the filament axis, so the filament axis can receive uniform force. The bearing which has a long service life has an arc-shaped support frame, and has big capability, while the spring is uneasy to deform. The spring can be driven by the bearing box to rotate in forward and reverse directions, the automatic centering support roll has the automatic centering function, and a sealed ring-shaped supporting seat has the advantages of beautiful appearance, high safety, and reliable protection. The utility model has the advantages of easy installation, convenient maintenance, high safety, and long service life.
Description
The utility model relates to a kind of belt transporter carrying roller.
The Qian type three joint carrying roller operations of using at present are not steady, and friction ring is even, easy sideslip of belt and job-hopping, under impact load, belt and carrying roller destroy big, and No. 90215932.1, China's patent application is though be better than Qian type three joint carrying rollers, belt deviation and job-hopping problem have been solved, belt is operated steadily, but, can only unidirectionally rotate because adapter shaft is right-and-left threaded thru-bolt, can not contrarotation, adapter shaft is loosening easily, even comes off, and brings very big inconvenience for installation and use, and processed complex, two ball-bearing casings are installed on adapter shaft, the cost height, and because of stressed irregular, bearing load is little, and bearing is short service life.Qian type supporting hanger is neither attractive in appearance, can not play protective action again.Adopt the straight-bar supporting bracket, holding capacity is little.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, operate steadily and provide a kind of, sideslip is not job-hoped, auto-centering, the silk axle mounting is firm, and forward and reverse rotation all can not become flexible, and installs, use very convenient, adopt tapered shaft strength evenly reasonable, cost is low, the bearing long service life; Adopt the osed top round bearing, can protect effectively, and attractive in appearance; Adopt arc support, holding capacity is big, the on-deformable auto-centering carrying roller of spring.
The purpose of this utility model realizes by following approach: the osed top round bearing is housed on arc support, by bolted connection bearing seat and pedestal cap, there is hangers the bearing seat both sides, being mounted on the side opens in the dead front type round bearing of mouth hanging, be sleeved on the tapered bearing on the silk axle of boss, be encapsulated in the bearing seat, seal ring also is housed in the bearing seat, there is the silk axle of boss to be connected with spring housing, and it is fastening by clamp nut and spring washer, have on the silk axle of boss to have keyway, advance keyway tightening silk axle, do not become flexible when making the forward and reverse rotation of spring housing by the clamp screw latching that is contained on the spring housing.The spring spinning at one end outwards has on the spring housing of crochet and welding.The oil hole bolt is arranged on the pedestal cap, and the auto-centering carrying roller adopts the staggered installation of positive and reverse return rotation structure, cancels each other and auto-centering along the hand of spiral propelling thrust.
Auto-centering carrying roller of the present utility model, being sleeved on the silk axle has the tapered bearing of boss end and seal ring to be contained in the bearing seat, to prolong the service life of bearing.
Auto-centering carrying roller of the present utility model, spring housing are contained in the lower end to be had on the spring housing of outside crochet, and spring and firm welding are hooked in crochet.
The embodiment of the utility model in reference to the accompanying drawings is described in further detail.
Fig. 1 auto-centering carrying roller scheme drawing
Fig. 2 auto-centering carrying roller assembling scheme drawing
As Fig. 1, shown in Figure 2, auto-centering carrying roller of the present utility model, dead front type round bearing (3) is fixed on the arc support (12), round bearing (3) is gone up both sides and is had the mouth hanging (17) that mounts bearing seat (4), bearing seat (4) is connected by bolt (7) with pedestal cap (1), oil hole bolt (2) is installed on the pedestal cap (1), be sleeved on the tapered bearing (5) that the boss end is arranged on the silk axle (6), seal ring (15) is contained in the bearing seat (4), fastening with silk axle bonded assembly spring housing (10) by clamp nut (8) and spring washer (9), spinning is advanced positioning spline (14) anchoring filament axle (6) on the silk axle (6) at the binding bolt (13) on the spring housing (10) pin, and silk axle (6) can not become flexible when forward and reverse rotation.Hold and the spring (11) of drive belt is sleeved on the lower end and has on the spring housing (10) of outside crochet.Spring (11) and firm welding are hooked in crochet, and bearing seat (4) drives the forward and reverse staggered rotation of spring (11), makes the belt auto-centering.Hangers (16) on the bearing seat (4) is mounted on the mouth hanging (17) of side of round bearing (3).
The utility model has the following advantages compared to existing technology: silk axle firm and reliable connection, and forward and reverse rotation can not become flexible; Adopt tapered bearing, stressed evenly reasonable, the bearing long service life; Adopt arc support, holding capacity is big. Spring is not yielding; Bearing block drives the forward and reverse staggered rotation of spring, self-centering; The enclosed type round bearing, safety attractive in appearance, protection is reliable, installs, and easy to maintenance, safe and reliable, the life-span is long.
Claims (3)
1, a kind of auto-centering carrying roller, comprise spring (11), there is the bearing seat (4) of hangers (16) both sides, pedestal cap (1) with bearing seat (4) suit, be installed in the oil hole bolt (2) on the pedestal cap (1), clamp nut (8) and the spring washer (9) of spinning on silk axle (6), the bolt (7) of adapter shaft bearing (4) and pedestal cap (1), it is characterized in that also comprising the spring housing (10) that crochet is arranged with spring (11) bonded assembly lower end, an end that connects spring housing (10) have boss above have the silk axle (6) of positioning spline (14), be packed in spring housing (10) and go up the tight fixed bolt (13) of the positioning spline (14) on the pinning silk axle (6), be installed in seal ring (15) and tapered bearing (5) in the bearing seat (4).
