Abstract
The utility model relates to chain transmission cases, in particular to a chain transmission case lubricating and pre-heating device. The technical scheme includes that the device is formed by a heater, a transmission case and oil pump outlets. A hole is arranged between the two oil pump outlets on the lower portion of the transmission case, the heater is installed inside the hole, a flange plate is fixed outside the hole, the outer end of the heater is fixed via a bolt, and the inner end of the heater is arranged inside lubricating oil. The device has the advantages that the lubricating oil of the transmission case is pre-heated by a temperature control system, and when a device runs normally for a period of time and temperature and pressure are normal, the temperature control system automatically disconnects, thereby not only preventing premature deterioration of the lubricating oil due to over heating, but also guaranteeing normal viscosity of the lubricating oil.
Description
One, technical field:
The utility model relates to a kind of chain transmission case, and particularly a kind of chain transmission case lubricates Preheating unit.
Two, background technique:
The chain transmission case is the linkage in the drilling equipment; the sprocket shaft bearing of transmission case inside, chain, tooth cover all are the oil lubrication that relies on the gear oil pump pumping; belong to force-feed lubrication system; the residing lubricated working environment of internal operations parts is basic identical; lubricant oil is pressed to lubricated surface with viscosity preferably during proper functioning; form oil film in relative motion surface, movement parts is played a protective role.But winter, sharply descended the working life of movement parts because the effect of lubricant oil solidifying point (being generally-5 ℃～-20 ℃) causes lubricating oil viscosity to increase, and mobile performance descends, and relative motion surface can not get effectively lubricating, forms dry friction.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of chain transmission case to lubricate Preheating unit, by thermostatically control, has guaranteed the reliable greasy property of lubricant oil, thereby has guaranteed the safe operation of chain transmission case.
Its technological scheme is: mainly be made up of heater, transmission case and oil pump filler opening, between two oil pump filler openings of transmission case bottom, open a hole, heater is installed, in the hole at hole outer fixing flange plate, by the outer end of bolt heater, the inner of heater is located in the lubricant oil.
The outer end of above-mentioned heater connects anti-explosion terminal box.
The beneficial effects of the utility model are: by temperature control system transmission case lubricant oil is carried out preheating, when the temperature control system automatic disconnection just often of equipment normal operation a period of time temperature, pressure, both prevented that superheating from causing the rotten too early of lubricant oil, guaranteed the normal viscosity of lubricant oil again.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is circuit diagram of temperature control system of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
The utility model mainly is made up of heater 2, transmission case 3 and oil pump filler opening 4, between two oil pump filler openings 4 of transmission case 3 bottoms, open a hole, heater 2 is installed in the hole, at hole outer fixing flange plate, by the outer end of bolt heater 2, the inner of heater 2 is located in the lubricant oil.
The outer end of heater 2 connects anti-explosion terminal box 1, and anti-explosion terminal box 1 connects temperature control system, and specifically with reference to accompanying drawing 2: wherein SB1 is a stop button, and SB2 is a start button, and KM is a main contactor, and Q is the power supply insertion switch.SCR is a solid-state relay.In this control wiring, its temperature control part divides the temp controller that adopts band PID to regulate to control.On lubricating pipe, install a temperature transducer in addition additional, monitor the temperature of lubricant oil in real time, and the current signal that temperature signal changes into 4～20mA is transferred to temp controller, temp controller is according to the control of setting temperature (being generally 10-20 degree centigrade) utilization to solid-state relay on the main line, come the on/off of control heater, thereby can control the temperature of lubricant oil accurately.
When entering winter construction, connect power supply to heater, by temperature control system transmission case lubricant oil is carried out preheating, when the temperature control system automatic disconnection just often of equipment normal operation a period of time temperature, pressure, both prevented that superheating from causing the rotten too early of lubricant oil, guaranteed the normal viscosity of lubricant oil again.The utility model has improved the functional reliability of chain-driven in winter equipment greatly, should as winter working specification a job treat, only make lubricant oil keep good lubricating property, could reduce the generation of accidents such as transmission case excessively heated axle, chain rupture bar, enhance productivity.
