Which parts of the punch need to be lubricated

According to the operating instructions, three zones must be lubricated in the hammer drill. This will extend the life of the device and equipment, and facilitate the operation of the tool. Let’s see what exactly needs lubrication and why.

Working equipment

Working equipment (drills and crowns), inserted into the cartridge, are under enormous strain. They receive from 1000 to 5000 beats per minute, transmitted to solid material, so that the tool easily passes stone, concrete screed, brick and other obstacles.

The operating manual instructs you to lubricate the shank of the drill before each use. If working with a hammer drill is carried out during the day, then the operator is required to periodically remove the drill and check for grease on the shank. Without lubrication, the assembly will quickly overheat and break, which will require not only the purchase of new equipment, but also the repair of a cartridge.

Lubricant for drill punch is applied to the grooves (two or five, depending on the type), which are fixed with locking wedges. It is first required to wipe the outside with a cloth to remove any dust and dirt. The product is usually squeezed out of a tube. Enough 1 g for uniform application. When changing the drill, chisel and other equipment, it is necessary to lubricate each time. After removing the drill or other device, you need to wipe the end face with a napkin so that it does not stain the suitcase and surrounding objects during storage.

Proper lubrication of the drill punch.

Lubricant for drills reduces friction in the fixing system and extends the life of the drill shank (if this section "converges", then even with the whole breakdown part with a winning nozzle, the inventory will not be suitable for work). Also, the punch lubricant protects against the ingress of dust, holding it on itself. Small particles of a crushed wall and other debris do not penetrate the instrument.

Cartridge

When buying a new hammer drill, its cartridge is dry. The user needs to lubricate the entry point of the snap-in, since the greatest friction occurs here. This action will protect the unit from excessive wear and dust penetration deep into.

Gearbox

This unit is responsible for transmitting torque from the electric motor to the cartridge. Internal parts here are subject to increased friction when operating at high speeds and elevated temperatures. Another mechanism is gradually clogged with debris, dust and dirt. To reduce wear, manufacturers provide it with a special coating, but this is not enough for everyday work, therefore, after a long period of operation, it is necessary to disassemble the housing and apply grease to the gearbox. If you do not know how to do this, then the tool must be taken to the service, where the wizard will perform this work.

The gearbox can be of two types:

1. With separate performance from the strike group. Here, the reciprocating mechanism for striking is made separately. It consists of a crankshaft and piston group, creating a force transmitted to the cartridge. The system has its own lubrication. The gearbox is only responsible for the rotation of the snap.

Separate rotary hammer reducer from shock group.

2. With a single ratchet type implementation. In this case, the gearbox also includes the shock mechanism (“drunken bearing”). The lubrication for the gearbox of the punch and hammer assembly is common here and is applied by the operator according to the schedule, depending on the frequency of operation of the device.

Gearbox with shock mechanism.

The gearbox itself consists of two gears. They can have straight or oblique teeth. The latter are designed for increased load.

There is a new type of gearboxes with planetary gear including more than two gears. Thanks to this mechanism, the gear ratio can be changed. the rotor of the engine rotates quickly, and the cartridge slowly. This gives increased power (rotation power) at a low number of revolutions. The equipment heats less, but does not wedge, but confidently drills solid material.

Planetary reductor.

In the ratchet mechanism, in addition to the friction of the gears against each other, longitudinal movement is also carried out. The small gear is equipped with a movable mechanism that moves back and forth up to 2000-4000 times per minute. This whole mechanism should be sufficiently lubricated, otherwise the assembly will quickly wear out and loose.

The shafts themselves are also installed in bearings, which may have their own lubrication (bearings of a closed type) or common with a gearbox (bearings of an open type). Without proper lubrication, the balls in them will be erased, which will lead to backlash and runout of the cartridge, as well as increased volume during the operation of the punch.

Varieties of tools and lubricant requirements for rotary hammers

It is important to remember that the lubricant for the drill and gearbox is not the same thing! For example, the manufacturer Makita, these substances have a completely different composition. Therefore, when choosing a lubricant, you always need to pay attention to its purpose, otherwise you can spoil the tool.

Lubricant for drill punchers

However, the lubricant must be suitable for use on rotary hammers with certain characteristics (power, number of revolutions and impacts), then it is logical that the properties of such a lubricant will be similar. Some lubricant manufacturers indicate

If you use a hammer drill for many hours a day, then buy a special grease, designed to work at high temperatures. For imported tools, it is better to purchase imported lubricants.

Lubricant for rotary hammer gearboxes

Hammers are sold ready to use, so initially in its gearbox there is enough lubrication for the first time. But subsequently, it will need to be disassembled and re-lubricated.

Attention. There are universal greases (nigrol, lithol, salidol, etc.) used to lubricate household appliances, rubbing car parts, electrical appliances. But for perforators (household and professional) it is better not to use them.

It requires a specialized substance, designed specifically for hard work in conditions of increased heating (because the rotational speed of the rotor of the washing machine is much lower than that of a perforator). Close in composition is a means for refueling in a CV joint of a car, but not everything is so smooth here. The gearbox has specific processes (sharp extrusion of the lubricant upon impact with a frequency of 4000 per minute), which requires unique properties from the lubricant. Therefore, general greases are not applicable here. But to purchase only the grease of the same brand as the tool is not necessary.

Here are the properties that a lubricant must have for a rotary hammer gearbox:

  • Corrosion protection. The gear housing is made of aluminum and its alloys, as well as alloy steel. The ductile substance should help protect against rust or plaque on both types of metals.
  • High adhesion. The tool should adhere so much to the details that, despite the impact of shock and high speed, it will retain a thin film over the entire surface.
  • Delay and removal of garbage. Construction dust can get into the gear housing. A high-quality lubricant collects abrasive particles on itself, binds them and displays them on the inner walls. This prevents settling inside the gears.
  • Water resistance. After cooling, a reduced pressure is formed in the gearbox, which helps to draw in air. If its humidity is high, then it can condense on the surface of the mechanism. The lubricant must protect the parts from water and do not form an emulsion during whipping.
  • High temperature drop formation. The gears become very hot from friction and when rotating at high speed, they discard the lubricant. The thicker the composition and the longer it liquefies before dropping, the more reliably the gearbox is protected.
  • Property recovery. After cyclic heating and cooling, the properties of the lubricant must be restored, otherwise it will cease to fulfill its functions, despite a sufficient amount.
