Description

BOX. FROM DRIVE GEARS TO STRAIGHT NGLES Field of the Invention This invention relates to a gearbox for transmitting movement from a first axis to a second axis, the second axis that is spaced from the first axis and that extends perpendicularly in another way to the first axis. More particularly, this invention relates to a gearbox of the preceding character, which is intended to be used only intermittently and only to transmit low levels of torque from the first axis to the second axis.

Background of the Invention The U.S. patent application Serial No. 08 / 854,042, which is assigned to the assignee of this application, discloses an article transfer device, which is usually referred to as an annealing tunnel loader or stacker, which is intended to transfer a plurality of containers. of glass formed recently, in a linear array, and Ref.031283 at the same time, transversely from a conveyor apparatus carrying the containers to a heat treatment device, which is usually called an annealing tunnel. The U.S. Patent No. 5,044,488 (Bolin), the description of which is incorporated herein for reference, discloses an alternative version of an annealing tunnel loader or stacker and describes the required three-axis movement that an eradust rod of the tunnel loader or stacker of annealing must suffer during each cycle of transfer of the containers. An annealing tunnel feeder for glass containers "of the type described, is provided with service by a feed conveyor, usually called a transverse conveyor, whose upper conveying path must be carefully placed in elevation to be capable of presenting the container for the appropriate transfer to an annealing tunnel conveyor by the annealing tunnel loader This requirement can be met by providing the transverse conveyor apparatus with a plurality of drive gear boxes at right angles, many of which they are placed in relatively inaccessible locations, and in any case in a relatively high temperature environment due to the proximity of the transverse conveyor with respect to the annealing tunnel and the latent heat of the containers at the entrance to the annealing tunnel. of impulse gears Res to right angles only need to be used intermittently, however, prior to a change in the position of the lift of the conveyor in one or more locations, and they are only used to transfer fairly low levels of torque, being operated typically manually. Therefore, these right-angled drive gearboxes do not need to be massive or robust, and a fairly simple and relatively inexpensive gearbox is usually more than adequate for this service. However, it is important that such a gearbox be easy to remove for maintenance and lubrication and that it be closed during operation to keep dust and foreign particles out of the gears, and to keep the lubricant in contact therewith.

Brief Description of the Invention In accordance with the present invention, an enclosed, right-angled driving gearbox is provided which is suitable for intermittent use to transmit low levels of torque. The gearbox of the present invention comprises upper and lower housing elements that are fixed or secured uncoupling from each other to define a space, and first and second axes, each of which has a gear that is keyed or fixed to another way to them and placed within a space defined by the upper and lower housing elements. The first and second axes are spaced apart from each other and the gears carried by the first and second axes engage in a driven manner with each other at a location within the space defined by the upper and lower housing elements. When the first and second axes rotate only intermittently, the housing does not need to be provided with separate bearings or bushings to accommodate the rotation of the shafts, it being sufficient that the upper and lower housing elements each be provided with complementary half-cylindrical recesses to form cylindrical openings that rotatably couple the first and second ones. axes Accordingly, it is an object of the present invention to provide a relatively inexpensive, relatively enclosed, straight-angle driving gearbox for transmitting movement from a first axis to a second axis that is spaced from the second axis and extending from another way generally perpendicular with respect to it. It is a further object of the present invention to provide a gearbox of the preceding character that does not require separate bearings or bushings to accommodate the rotational movements of the first and second axes.

Brief Description of the Drawings Figure 1 is a fragmentary plan view of a combination of annealing tunnel and annealing tunnel of the glass containers, in which a transverse conveyor placed between the annealing tunnel loader and the annealing tunnel, is provided with a plurality of driving gear boxes at right angles according to a preferred embodiment of the present invention; Figure 2 is a perspective view on an enlarged scale of a gearbox of the type shown in Figure 1; and Figure 3 is an exploded perspective view, on a scale of Figure 2, of the gearbox of Figures 1 and 2.

Detailed Description of the Preferred Modality Figure 1 illustrates an annealing tunnel installation of the glass containers, in which an annealing tunnel L has a conveyor apparatus C, for example, an endless wire mesh conveyor, for transporting the glass containers B formed recently, on a transverse conveyor device X through the annealing tunnel L, to relieve the residual formation stresses in the containers B. The containers B are transferred at the same time from the transverse conveyor X to the conveyor C by a bar push P from a loader-to a three-axis annealing tunnel stacker, which can be of conventional construction, the B-vessels that pass through a series of hearths of the hearth D on its path or route from the conveyor apparatus X up to the conveyor apparatus C. From time to time it is necessary or desirable to be able to adjust the elevation of a superior trajectory of the conveyor X, for example, so that it is capable of aligning the level of the conveyor apparatus X with the level of the upper path of the conveyor apparatus C, and for this purpose a plurality of manually operated adjustment mechanisms are provided, each one involving a gear box 10 impellers at right angles. As shown in Figure 2, a gearbox 10 has a housing 12 in the shape of a parallelepiped, and the housing 12 is composed of upper and lower housing elements 14, 16. The housing 12, which has a cavity or inner space, encloses a driving gear 18, which is keyed or otherwise fixed to a driving shaft 20, and a driving gear 22, which is keyed or otherwise fixed to a driving shaft 24 and is coupled to The driving shaft 18. The longitudinal central axis of the drive shaft 24 is spaced from the longitudinal central axis of the drive shaft 20, and extends otherwise perpendicularly thereto. The lower housing element 16 has a lower wall, not shown, a first identical pair, spaced apart, opposite, with vertical side walls 26, 28, and a second identical, spaced-apart pair of vertical side walls 30, 32, the first side walls 26, 28 extending a substantially greater distance from the lower wall of the lower housing member 16 than the second side walls 30, 32. Similarly, the upper housing element 14 has an upper wall 34 , a first identical pair, spaced apart, opposite, of side walls, only one of which, the side wall 36, is shown, and a second identical pair, spaced away, opposite, of side walls 38, 40, the second walls laterals 38, 40 extending a substantially greater distance from the upper wall 34 than the first lateral wall 36. Each of the first side walls 26, 28 of the housing element lower housing 16, has a semi-cylindrical recess 42 in a free edge thereof, and each of the second side walls of the lower housing element 16, including the side wall 30, has a semi-cylindrical recess 44 on a free edge thereof. Similarly, each of the first side walls of the upper housing element 14, including the side wall 36, has a semi-cylindrical recess 46 in a free edge thereof, and each of the second side walls 38, 40 of the wall element. upper housing 14 has a semi-cylindrical recess 48 in a free edge thereof. Accordingly, when the housing elements 14, 16 are removably joined together, the fasteners or threaded fasteners 50, 52 are provided to serve for this purpose, the opposite recesses 42 of the lower housing element 16 are disposed complementary to each other. the opposite recesses 46 of the upper housing element 14 to form cylindrical openings to rotatably support the drive shaft 24, at locations on opposite sides of the drive gear 22. Similarly, when the housing elements 14, 16 are joined together, the opposite recesses 44 of the lower housing element 14 are disposed in complementarity with respect to the opposite recesses 48 of the upper housing element 14 to form cylindrical openings, to rotatably support the drive shaft 20 on opposite sides of the drive gear 18. In this regard, because of the gear box 10 is proposed to be operated only intermittently and only under low levels of torque therein, the cylindrical openings defined by the recesses 42, 46 and 44, 48, need not be provided with separate bearings or bushings, and this eliminates the elements that could otherwise materially increase the cost of the gearbox 10. It was also noted that the upper housing element 14 can be easily removed from the lower housing element 16, to inspect or replace the gears 18, 22 or to repair the housing 12, for example, and this can be done simply by removing the fasteners or threaded fasteners 50, 52, as described so far. Accordingly, the gearbox 10 is not only relatively inexpensive, because it does not have or require separate bearings or bushings to rotatably support the shafts 20, 24, as described heretofore, but it is also very simple to disassemble for purposes of repair or replacement of any of its constituent elements that are subject to wear or damage to the operation. Indeed, the fact that separate bushings or bearings are not used, facilitates the disassembly of the housing 12. Also, the fact that the gearbox 10 completely encloses the gears 18, 22, because it must ensure that the recesses 42, 46 and 44, 48 are additionally arranged to define the cylindrical openings, as described hitherto, ensuring that dirt and other foreign particles can be kept out of the contaminating contact with the gears 18, 22, and that a suitable lubricant, such as like a viscous fat, it can be kept in mesh with them. Although the best mode contemplated by the inventor for carrying out the present invention at the date of presentation thereof has been shown and described here, it will be apparent to those skilled in the art that suitable modifications, variations and equivalents can be made without departing from the scope of the invention, such scope is limited only by the terms of the following claims and the legal equivalents thereof.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it refers.

Having described the invention as above, property is claimed as contained in the following
