INDUSTRIAL GEAR OIL
 

The gear lubrication oil is a machine component of particular significance for the transmission. During operation, the lubricants come into contact with most of the other machine elements of a transmission. Apart from the important function of lubricating the sliding rolling contacts, the oil also fulfils the task of cooling and removing the friction heat generated in the sliding rolling contacts.

A comparison of the expenses and cost relating to the production or manufacture of the machine elements of the transmission such as the roller bearings, toothed wheels, shaft, seals or  earboxes , show that, in general, the lubricant is a transmission components which can be relatively simply produced at low cost. However, in order to ensure the reliable and long term operation of a transmission, the selection of the lubricants in comparison to the selection of the other machine components, is of decisive significance

During the transmission construction. For eg. a new unlubricated ball - bearing used in vehicle’s generator reached a service life of four minutes. A ball – bearing of the same type used under the same operating conditions reached a service life of several hours after application of approx. of 2ml oil on to the bearing’s tracks.

Various types of lubricants are used in the lubrication of transmission, where by a transmission lubricating oil mainly consists of a base – oil and an additive adjusted to the base oil and the application.

Oil LUBRICATIONS

Oil is generally considered to be more effective lubricant, and is to be preferred if the sealing arrangements are adequate, especially where the operating temperature or surface speed of the balls or rollers is high. Oils having viscosities ranging from that of the thinnest spindle oil to that of a heavy steam-cylinder oil are used. The viscosity required for any given set of conditions depends on size speed, load, and temperature of the bearing. Mineral oils of high quality should be chosen, because of their resistance to form resinous products, or acids which might damage the highly polished working surfaces of the bearing.

The method used to apply the oil depends mainly on the running speed of the bearing. Use of proper method is especially important with high-speed bearings, which are liable to overheat through churning of the oil if it is not correctly applied. The following means of application are suitable :
  • Oil bath and splash systems - low and medium speeds.
  • Circulating systems - medium speeds.
  • Spray or mist - high speeds.
Ball and roller bearings may be lubricated by oil or grease, the choice of lubricant usually being decided by operating conditions and bearing design.
 

LUBOL GAROCHEM

GEAROCHEM is extreme pressure gear lubricant blended from high viscosity index, solvent refined high quality base oils. It contains sulphur / phosphorous additives which provides very good antiwear and anti corrision property.

RANGE :

VG: 46, 68, 100, 150, 220, 320, 460, 680, 1000
Non ISO VG grades can also be made available for critical applications provided quantities required are commercially feasible to blend and market.

APPLICATION:
  • All types of enclosed high performance industrial gear drives encountered with extreme load / speed conditions.
  • Suitable for worm gear applications.
  • Also suitable for circulating and splash lubricated systems and also in oil mist applications.

BENEFITS :

  • Satisfy the lubricants requirement of a wide variety of gears.
  • Outstanding oxidation and thermal stability which serves to extend oil service life even at high bulk oil temperature.
  • Provide good protection against corrosion.
  • Provide protection against wear due to good EP additives.

Very slow foaming tendency leading to reliable lubrication even at high speeds.
