Definitions
- the invention relates to a measuring system that is installed stationary on machine housings in order to permanently detect the machine vibrations (structure-borne noise) and / or the temperature in order to indicate changes or faults in the machine system at an early stage.
- measuring systems In order to constantly monitor the machine status, in particular the status of the rolling bearings in machines, measuring systems (vibration monitors) are arranged stationary on machines. For this purpose, these vibration monitors are screwed into the lubrication hole in roller bearing housings in order to detect the machine vibrations in the immediate vicinity of the roller bearing. To enable relubrication of the rolling bearings without disassembling the vibration monitor, the vibration monitor has a hollow mounting pin.
- the essence of the invention is that the vibration sensor is connected directly to the machine housing via a metal sleeve, which is arranged outside the mounting pin.
- the circuit boards are mounted in a housing that is arranged around the mounting pin via damping elements.
- the housing is connected to the metal sleeve.
- the vibration sensor housing freely around the assembly pin.
- the housing can be aligned when screwing in, so that cable connections or optical display devices may point in a certain direction. The machine operator or maintenance personnel can read these display elements directly.
- the assembly pin is tightened (in the end position)
- the metal sleeve is pressed against the vibration sensor housing and thus contacts the vibration sensor with the metal sleeve. This is a direct connection for structure-borne noise between the machine housing, Metal sleeve and vibration sensor created.
- the housing of the measuring system is non-positively and non-rotatably fixed in the end position.
- the vibration monitor or the measuring system 1 is shown in FIG.
- the mounting pin 2 is screwed with its thread 4 into the lubrication hole opening 16 of the receiving machine housing 15.
- the mounting pin 2 is screwed in with a wrench size 4a.
- the assembly pin is screwed in, the housing 5, 5a and the vibration sensor housing 7 can be rotated about the latter.
- the metal sleeve 6 is then pressed against the vibration sensor housing 7 until it comes into contact with the projection 8 of the mounting pin 2.
- the metal sleeve 6 is also directly connected to the lower housing part 5 of the measuring system 1 in a rotationally fixed manner.
- the lower part of the housing 5 is non-positively and non-rotatably fixed on the machine housing.
- the upper housing part 5a is screwed to the lower housing part 5 and thus also fixed.
- the damping elements in the housing are designated by the reference number 13 and lie on the one hand between the two housing parts 5, 5a and on the other hand between the upper housing part 5a and the mounting pin 2.
- Another possibility is the arrangement of a damping element 13a (O-ring) between Printed circuit board 9 and housing 5.
- the printed circuit board with the electronic components 9 is arranged within the lower housing part 5 and, in this example, is rotationally symmetrical to the mounting pin 2.
- the circuit board is held by the lower housing part 5 and has no direct connection to the mounting pin 2.
- a battery 11 is provided on the circuit board 9, which enables this measuring unit to be operated without a cable connection.
- an opening 12 is provided in the lower housing part 5, through which a power supply via cable would also be possible.
- a temperature sensor 10 is provided, which is pressed outside the circuit board against the mounting pin.
- the battery 11 on the printed circuit board 9 can be replaced by unscrewing the upper housing part 5a.
- the operating state of the machine system is indicated to the operator or the maintenance personnel via light-emitting diodes 14 which are arranged on the printed circuit board 9.
- the upper housing part 5a is made of a transparent plastic.
- the housing 5, 5a can be rotated relative to the mounting pin during tightening, it can be oriented in such a way that the cables 12 or the light-emitting diodes 14 lie in such a way that they can be easily recognized.
- the lubricating grease can get into the rolling bearing housing from the outside without having to dismantle the measuring system.
- the housing 5, 5a of the measuring system 1, the vibration sensor housing 7, the printed circuit board 9 and the metal sleeve 6 are designed to be rotationally symmetrical about the assembly pin.
