Description

Technical field

The utility model relates to adapters for starters of internal combustion engines and can be used in the construction of gear type starters for engines of trucks and agricultural machinery.

State of the art

When installing starters of various models on various types of internal combustion engines, there is a design compatibility problem associated with the different arrangement of the mounting holes of the elements to be connected, as well as with the use of transmission gears of different sizes.

One solution to this problem is the use of adapters for starters.

The closest analogue of the claimed utility model is the adapter for the starter, disclosed in US patent US 5163335, 11.17.1992. This adapter is an overlay on the starter, in which a hole is made for the starter shaft, holes for connecting to the starter in various angular positions, lying on the first circle, and holes for connecting to the engine, lying on the second circle. Moreover, the first and second circles have a center that coincides with the Central hole for the shaft, and the diameter of the second circle is greater than the diameter of the first circle. This design provides the ability to connect the starter with engines having different locations of the mounting holes. However, this analogue still does not have a sufficient level of versatility, since when it is used in gear type starters, the problem of combining the starter gear with the engine drive gear is not solved, because the main and transmission shafts are mounted on the starter housing.

Utility Model Disclosure

The objective of the claimed utility model is to eliminate the disadvantages of analogues.

The technical result of the utility model consists in the possibility of constructively combining various models of the starter with various types of engines, i.e. in the universalization of the starter assembly.

The specified technical result is achieved due to the fact that the adapter for connecting the gear type starter to the internal combustion engine contains a housing in which holes are made for connecting the adapter to the starter in various angular positions, lying on the first circle, holes for connecting the adapter to the engine, lying on the second circle, the first and second circles having a common center, and the diameter of the second circle is larger than the diameter of the first circle, and a transmission shaft is installed in the housing l with the first gear placed on it for transmitting torque to the transmission shaft from the starter gear and the second removable gear (9) for engagement with the engine drive gear.

In addition, there are private options for implementing the utility model, according to which:

- the transmission shaft is mounted in bearings mounted in the adapter housing.

- a third hollow gear is mounted in the housing around the transmission shaft for engagement with the starter gear, while the transmission shaft with gears placed on it is made with the possibility of translational axial movement to ensure engagement or disengagement of the first gear with the inner surface of the third hollow gear and the second gear with the engine gear .

Due to the design of the adapter housing with holes for mounting to the starter housing and the engine, it is possible to install the adapter in various angular positions, which allows you to choose the necessary position for installing the starter in a confined space, as well as for mounting the adapter to the engine housing, which can have various layout options mounting holes.

In this case, unlike the closest analogue, a reducer shaft with gears is also installed in the adapter housing for transmitting torque from the starter to the engine. This makes it possible to adapt it for various types of gears of the engine drive when installing the adapter, since the gear of the adapter, which is engaged with it, is removable.

Thus, the entire set of features of the utility model is aimed at achieving a single technical result, which consists in the possibility of constructive combination of various models of starters and engines.

in FIG. 1 shows a General view of the claimed adapter from the side,

in FIG. 2 shows a General view of the claimed adapter in front,

in FIG. 3 shows a sectional view of an adapter mounted on a starter,

Utility Model Implementation

The claimed adapter includes a housing (1) having holes (2) for mounting to the starter housing (3), as well as holes (4) for mounting to the engine housing (not shown in the drawings). The holes (2) and (4) are respectively located on the first and second circles with a common center, and the diameter of the second circle is larger than the first. At the same time, at least three holes (2) are made in the housing (1) for fastening to the starter and at least two holes (4) for fastening to the engine. Preferably, the adapter comprises six holes (2) symmetrically distributed along the first circumference at intervals of 60 ° to allow the starter (3) to be mounted in various angular positions.

A central hole (coinciding with the center of the first and second circles) is also made in the adapter housing (1), in which a drive unit (5) is installed, including a transmission shaft (6) located in bearings (7) installed in the housing (1). Two gears (8) and (9) are rigidly fixed to the shaft (6), extending beyond the dimensions of the housing (1) from its different sides. The first gear (8) transmits torque to the transmission shaft (6) from the starter gear (10) (Fig. 4) mounted on the starter shaft, which is parallel to the transmission shaft (6) and is the starter armature shaft (11). A second removable gear (9) engages with a motor drive gear (not shown). Moreover, to ensure gear engagement, the adapter design provides for the third hollow gear (12) installed in the housing (1) around the transmission shaft (6), having teeth on the inner surface for engagement with the first gear (8) and being engaged with external teeth with starter gear (10). In this case, the transmission shaft (6) together with gears (8) and (9) has the possibility of translational axial movement under the action of the lever (13) of the starter relay.

The device operates as follows.

Depending on the engine model, the necessary type of adapter is selected, having a suitable location of the holes (4) and their distance to the center (one type of adapter covers a number of engine models). A gear (9) suitable for the engine is also installed on the adapter (a set of gears is included). Using bolts, the adapter is connected to the starter housing (3) through the holes (2) in the required angular position. When connecting, the third gear (12) of the adapter engages with the gear (10) of the starter. Through the holes (4) the adapter is also attached to the motor housing. When the starter relay is turned on, the lever (13) moves the transmission shaft (6) towards the engine (in Fig. 2 to the left), together with gears (8) and (9), due to which the first gear (8) engages with the internal teeth of the third gear (12) (the gear 12 itself is stationary along the shaft axis), and the second gear (9) is engaged with the engine drive gear (not shown). Next, the torque from the armature (11), through the gear (10), gear (12), shaft (6) and gear (9) is transmitted to the engine drive gear.

The claimed adapter design provides its versatility for various models of starters and engines, as well as reducing the dimensions of the starter assembly and increasing the efficiency of its installation on the engine.
