Description

  There is no management method for the wear phenomenon of the groove due to aging of the V pulley, and there is no accurate measurement method at present because it is touched with a fingertip to judge the wear state of the groove.

  The wear of the V pulley groove is mainly due to deterioration over time. Various machines are operated 24 hours or on a timer. Machines that are stopped and operated every day have the largest torque during driving, so the slip phenomenon occurs and the situation of heat generation due to friction is repeated. At the same time, elongation occurs. If the V pulley is worn due to the deterioration of the V belt, the groove shape of the V pulley will be deformed even if it is replaced with a new V belt. Abnormal noise is generated, and abnormalities such as deterioration of the bearing, damage to the blades, and looseness of the mounting bolts occur. By continuing the operation, even if the V-belt is newly replaced, abnormal friction occurs on the contact surface of the non-uniform V pulley, causing a crack due to a rapid temperature rise and breakage of the V belt, resulting in an increase in power consumption in a short period of time. , CO2 emission accompanying the power consumption increases.

  The method for inspecting the wear of the V pulley groove is mainly performed by a tentacle with a fingertip, and judgment by an experienced skilled worker is required, and the numerical value cannot be measured accurately.

Transmission V-pulleys are frequently used in air-conditioning equipment such as buildings, buildings, and factories, and are essential mechanical parts for ventilation and air-conditioning. The V pulley gradually wears away due to friction with the V belt depending on the time and conditions of use, and the groove of the V pulley differs from the designed dimensions. Then, the looseness of the V-belt also progresses, and the slip phenomenon of the V-pulley and V-belt occurs, and changes such as the air volume, static pressure, and rotation speed of the equipment used for ventilation such as air conditioning equipment, contrary to power saving and energy saving. Occurs and power consumption increases. According to the V pulley groove wear measurement sheet according to the present invention, it is possible to contribute to CO2 reduction such as power saving and energy saving effect by appropriately managing the wear state of the groove of the V pulley.

  V pulleys and V belts are often used in building buildings, buildings, plant factories, hydroelectric power plants, thermal power plants, nuclear power plants, public facilities, etc., and ventilation and air conditioning equipment such as air supply, exhaust, air conditioning, and air conditioning It is widely used as a torque transmission method from a power source. Management of the V pulley groove wear status is one of the important inspection items related to energy saving measures, and it contributes to power saving, energy saving effects, and CO2 reduction, so the industrial applicability is very high. .

A fixed portion to be used, a writing space provided within the range of the convex portion to fill in the worn position of the groove and a measured value, a building used for the equipment in which the V pulley is used, a purpose of use, a system name to be used, Provided in a series of sheets that are cut out into a shape opposite to the shape of the V pulley, and an entry field specifying information including the type of the V pulley and the date of inspection.
The measuring rod is a non-painted tip portion inserted into a gap between the groove and the convex portion, a painted portion formed with the same thickness as the tip portion and color-coded for different sizes, and A grip portion provided at an end portion of the coating portion opposite to the tip portion,
The V pulley groove wear measurement sheet is fixed by bringing the fixing portions into contact with both side surfaces of the V pulley so that the convex portion is held in the groove of the V pulley to be measured.
By inserting a plurality of types of the measuring rods having different thicknesses into the gap formed between the groove and the convex portion in a state where the V pulley groove wear measurement sheet is fixed to the V pulley, Measure the worn position and the size of the gap,
Enter the measured position and the dimensions in the writing space;
Write the information in the entry field,
The V pulley groove wear measurement sheet is put in the V pulley to be measured and a construction photograph is taken for each machine as a recording photograph,
A method for managing the wear state of the groove of the V pulley, comprising managing a history of the progress of wear of the groove.
