Problems solved by technology

[0011] The water pump removal process described above is time consuming, expensive and sometimes results in damage to components during removal due to the use of inappropriate tools in the often very tight space within a car engine compartment
Also, in other systems that include pulleys, the procedure for removing them is similar to that described in step 2, however, there are specificities in each case
[0012] Until now, a pulley has not been developed that allows easy removal of internal combustion engine components, such as water pumps
Likewise, no convenient and inexpensive method has been developed for removing such a pulley with little or no damage to the system involved or its peripheral components

Embodiment Construction

[0032] According to the preferred embodiment and as figure 1 As shown, the present invention relates to a pulley, in particular a pulley for use in an internal combustion engine for transmitting rotational motion produced by the crankshaft of the engine, which is substantially cylindrical and has at least one first substantially circular main part 2 and At least one opening 7 for connection to at least one substantially rotatable shaft, these parts will be described in more detail below. The first main part 2 comprises at least one first hole 3 for positioning a protruding tool element.

[0033] An internal combustion engine is understood to be any engine providing a cyclic motion, for example an engine operating according to the Otto cycle, a diesel engine, a 2-stroke engine, a Wankel engine or even any other type of engine. Furthermore, there is no restriction on the use of the presently designed pulley 1 in other types of motors, such as electric motors, since this is tech...

Abstract

A pulley (1) is described, particularly used for the transmission of circular movements in internal combustion engines, featuring a set of additional orifices (3) to make possible the positioning of a tool (8) for its removal, as well as it also refers to a method to remove pulley (1) by means of a tool (8) with pins or similar projecting elements (8') and an internal combustion engine equipped with the pulley (1).

Description

technical field [0001] The invention relates to a pulley, in particular a pulley for transmitting circular motion in an internal combustion engine, which has a set of additional holes to make it possible to position a tool for the removal of the pulley, and the invention It also relates to a method of dismounting a pulley by means of a tool with a pin or similar protruding element, thereby allowing easy access and avoiding damage to the system located around the pulley, and an internal combustion engine equipped with the presently described pulley. Background technique [0002] Since it is difficult to use tools to perform the removal work of the water pump pulley belonging to the internal combustion engine cooling system of any automobile (or as another peripheral part of the alternator, air conditioning compressor, power steering hydraulic pump, etc.), when necessary Removal of this part can become expensive and time-consuming for maintenance work. Often, multiple tools a...
