RU193111U1 - Skewers rotation mechanism - Google Patents

Abstract

The mechanism of rotation of the skewers consists of a gearbox, motor, axis of rotation, on which the motor is mounted. The gearbox is made of gears, each of which is made with an axial hole, while the rotation axis is installed in one of the gears. The use of a gear reducer made of gears, which are made of steel by laser cutting, increases the reliability of this mechanism, and the axial holes of the gears in which the square seats are installed securely fix the skewers of various shapes inserted into them.

Description

The utility model relates to equipment for the thermal preparation of food products over an open fire and can be used for the preparation of barbecue and large-sized products from meat, fish, game, poultry and vegetables.

A technical solution is known, patented as (19) RU (11) 141000 (13) U1 - “MECHANISM OF ROTATION OF SHAMPOOS” IPC A47J 37/04 (2006.01), which describes a device containing removable food product holders in the form of skewers, a number of gears by quantity skewers, each of the gears is made with an axial hole, which is a seat for installing skewers, a removable motor for rotation, while one of the gears is made with the possibility of connection with the motor, characterized in that it contains a gear housing with gears for skewers and holes placed therein the darker part of the gearbox connected to the gearbox housing using tie rods; gears are made of cast aluminum; gear teeth are made in a straight form.

The disadvantage of this device is that the gears made of aluminum have low mechanical strength and break quickly, while the production of aluminum products is very expensive for small-scale production, because quite energy-intensive and requires special equipment.

The objective of the proposed technical solution is to create a mechanism for the rotation of skewers for barbecue, where the gears of the gearbox are made of steel.

The technical result consists in the manufacture of another mechanism, namely a more reliable mechanism for the rotation of skewers, where its reliability is higher than the reliability of the analogue due to the steel gears, rather than aluminum, using a technology more suitable for the manufacture of small-scale products. Compared to aluminum, steel gears made using laser cutting technology are more reliable, have a longer service life, and their production is cheaper. In seats that have a square section, skewers of various shapes are securely inserted. The gears of the gearbox can be made as solid (without cutouts, but heavier), so some of them, or all of them, with cutouts that reduce the weight of these gears, which allows to reduce the total weight of this mechanism and thereby increase the battery life leading to in motion the motor.

The claimed technical solution is illustrated by drawings, where:

in FIG. 1 - image of the rotation mechanism of the skewers with a short axis, top view,

in FIG. 2 - image of the rotation mechanism of the skewers with a long axis, top view,

in FIG. 3 - connection of gears of a reducer.

The positions in the drawings indicate:

1 - gear

2 - continuous gears,

3 - gears of the gearbox with cutouts,

4 - axial hole in the gear,

5 - sleeve with a seat,

6 - motor

7 - axis of rotation,

Description of the claimed technical solution

The inventive mechanism of rotation of the skewers includes a gear 1, a motor 6, an axis of rotation 7, on which the motor is mounted, where the gear 1 is made of gears (2 and / or 3), each of which is made with a circular axial hole 4, into which the sleeve is inserted square section 5, while in one of the gears the axis of rotation 7 of the motor is installed.

The axis of rotation 7 of the motor can be installed in the sleeve with a seat 5 both from the side of the installation of skewers, and from the opposite side in any of the gears.

When installing the motor on one side with skewers, the motor axis separately occupies the sleeve with a seat 5.

When installing the motor on the side opposite the skewers, the axis of the motor takes place in the bushing along with one of the skewers and is located towards this skewer.

Gear 1 (see Fig. 3) can have both continuous gears 2 (without side holes), and gears with side holes 3, or both.

The gears of the gearbox are made of steel by laser cutting.

The axis of rotation 7, if it is located on the opposite side to the location of the skewers, can have a length of 5 ÷ 25 mm, if it is located on the side of the location of the skewers - 350 ÷ 500 mm (comparable in length to the skewers). When this axis of rotation of the motor is mounted on a support for skewers 8.

Advantageously, the gearbox 1 consists of an odd number of gears (so that the load on the gears is uniform) and then the axis of rotation 7 of the motor 6 is located in the middle of the gearbox 1, but it is also possible to arrange the axis of rotation 7 with the edge, then the number of gears can be any.

The teeth of the gears are predominantly straight.

The seat in the gears is made rectangular, which allows you to insert skewers of various shapes into them.

Examples

For the rotation mechanism of skewers rotating only five skewers, all gears are solid, for the rotating seven skewers, three gears are solid, the rest with cutouts or all with cutouts, for rotating nine, eleven, etc. skewers - all gears with cutouts.

If the axis of rotation 7 of the motor and, accordingly, the motor 6 are installed in the center of the gearbox 1 from the side opposite to the installation of the skewers, axis 7 is inserted into the sleeve 5 on one side, and there is still a seat for the skewer on the opposite side. In the remaining gears of the gearbox, the seats 5 are intended only for skewers.

If the motor 6 is installed on the installation side of the skewers, only the long axis of rotation 7, on which the motor 6 is mounted, is installed in the central gear of the gearbox 1. The remaining gear seats are intended only for skewers. The axis of rotation 7 rests on a support for skewers 8.

The gears are made of steel by laser cutting, while the gear connected to the axis of rotation 7, to which the motor 6 is connected, is made solid 2, and the remaining gears can be cut out 3; all gears can be without cutouts 2; all gears can be cut 3.

In the inventive device, the gearbox may contain from 5 or more gears.

The gearbox is enclosed externally. The teeth of the gears are made in a straight form, which provides a small point of engagement of the gears with each other, and, thereby, ease of rotation. The seat for skewers in gears has a square shape - this makes it possible to use skewers of a wide range of cross-sectional options: square, in the shape of a corner, rectangular, etc.

The selected center distance between the gears of about 7 cm corresponds to the most optimal size of the product placed on the skewers - sufficient to accommodate pieces of medium-sized meat and, thereby, to reduce the effort and time for cutting meat.

The rotation of the gears of the gearbox allows you to evenly rotate the skewer with pieces of meat, fish, poultry, vegetables, etc. mounted on them.
