Abstract
The utility model relates to an oil tube type temperature sensor for locomotive electric machine shaft, formed by combining an oil tube (1) and a temperature sensor (2), wherein, the oil tube (1) is provided with a flow nipple (11) and a mounting hole; the temperature sensor (2) is fixed on the oil tube (1) and is arranged inside the oil tube (1) through the mounting hole; in addition, the temperature sensing head (4) of the temperature sensor (2) is arranged inside the intracavity of the oil tube (1). The utility model provides people with an oil tube type temperature sensor for locomotive electric machine shaft with simple and compact structure, low cost, small space usage, convenient installation, maintenance and disassembly, high sensitivity and ideal reliability and being suitable to be installed at high-speed rotary parts such as electric machine shaft.
Description
The utility model belongs to sensor field, specifically is a kind of locomotive engine shafting oil tubular type temperature sensor.
Along with improving constantly of China's train running speed, to locomotive operation safety, reliability is had higher requirement.In order to prevent to press at high speed rotating part position mounting temperature sensors such as wheel shaft, axle suspension bearing box, motor shafts, its temperature is monitored because of lacking the generation that lubricated wet goods causes major accidents such as the too high even seize of axle temperature.Yet, when design locomotive engine axle temperature degree sensor, while owing to be that motor is a gear case on the locomotive, the two spacing is only about 40mm, if adopt common temperature sensor, must on the motor shaft bearing cap, process a temperature sensor mounting hole by correct position.Carry out the processing of mounting hole and the installation of temperature sensor after when this just can only repair gear case being pulled down in locomotive.The back is installed just can carries out after needing maintenance and also must pulling down gear case when changing if sensor breaks down.More than, just proposed to design an urgent demand of the temperature sensor of a suitable above-mentioned particular surroundings to people.
The purpose of this utility model is exactly in order to satisfy above-mentioned requirements, for people provide a kind of simple and compact for structure, cost is low, can be installed in high speed rotating part position such as motor shaft, the locomotive engine shafting oil tubular type temperature sensor of little, the installation and maintenance convenient disassembly of taking up room, highly sensitive, good reliability.
The purpose of this utility model realizes by following technical proposals.
Locomotive engine shafting oil tubular type temperature sensor of the present utility model, combine by oil pipe (1) and temperature sensor (2), oil pipe (1) is provided with oil nozzle (11), oil pipe has mounting hole on (1), temperature sensor (2) is fixed on oil pipe (1) and goes up and insert from mounting hole in the oil pipe (1), and the temperature-sensitive head (4) of temperature sensor (2) places the inner chamber of oil pipe (1).
In the such scheme, the structure of described oil pipe (1) does not have strict restriction, and the function that has motor bearings filling lubricant grease gets final product.Oil pipe (1) is installed on the motor shaft, and the detected temperature of sensor (2) is the temperature of motor bearings.
In the such scheme, described temperature sensor (2) can be the temperature sensor of various structures.
In the such scheme, the mounting hole that described oil pipe (1) go up to insert temperature sensor is located at the side of oil pipe or top for well.
In the such scheme, described temperature sensor (2) is fixed on the oil pipe (1), and its fixed form can design arbitrarily.
The utility model is the designer sums up the science of coming out in long-term practice a design proposal, it has utilized the utilized space of existing equipment dexterously, solved the difficulty of the insufficient space that existing equipment stays, the oil pipe used of filling lubricant grease on temperature sensor and the original motor axle is scientifically combined, design a kind of simple and compact for structure, cost is low, can be installed in high speed rotating part position such as motor shaft, the locomotive engine shafting oil tubular type temperature sensor of little, the installation and maintenance convenient disassembly of taking up room, highly sensitive, good reliability.The utility model except that have the motor axle temperature monitored, still has function to motor bearings filling lubricant grease, only need during installation the oil pipe that filling lubricant grease on the original motor axle is used pulled down and change new oil pipe formula temperature sensor and get final product, do not need the disengage gear case, so the installation and maintenance convenient disassembly.
Further describe the utility model below by embodiment, the utility model is not limited only to described embodiment.
Accompanying drawing 1 is an one-piece construction synoptic diagram of the present utility model.
Accompanying drawing 2 is the cut-open view of snap ring, plug and oil pipe connecting portion in the accompanying drawing 1.
Accompanying drawing 3 is the left view of snap ring, plug and oil pipe connecting portion in the accompanying drawing 1.
Among the figure: 1, oil pipe; 2, temperature sensor; 3, screen pack: 4, temperature sense head; 5, left snap ring; 6, right snap ring; 7, plug; 8, screw; 9, sealing gasket; 10, attachment screw; 11, oil nozzle.
Shown in Fig. 1～3: locomotive engine shafting oil tubular type temperature sensor, combine by oil pipe 1 and temperature sensor 2, oil pipe 1 is provided with oil nozzle 11, have mounting hole on the oil pipe 1, temperature sensor 2 is fixed on inserts on the oil pipe 1 and from mounting hole in the oil pipe 1, and the temperature-sensitive head 4 of temperature sensor 2 places the inner chamber of oil pipe 1.
In this example, the mounting hole that inserts temperature sensor on the described oil pipe 1 is located at the side of oil pipe.
The fixed form that this routine described temperature sensor 2 is fixed on the oil pipe 1 is: the perforate section that snap ring 5,6 usefulness attachment screws 10 in the left and right sides is fixed in oil pipe 1.With screw 8 left snap ring 5 is fixed together with aviation plug 7.Plug 7 links to each other with the upper end of inserting the temperature sensor 2 of oil pipe 1 inner chamber from oil pipe 1 mounting hole by a side of snap ring 5, is provided with sealing gasket 9 at snap ring 5, temperature sensor 2 with the joint portion of oil pipe 1 mounting hole.
The bottom of oil pipe 1 is that the lower end of temperature-sensitive head 4 is provided with screen pack 3 in this example, also can not establish this screen pack.
