Description
Technical field
The invention belongs to technical field of lubricating grease, particularly relate to composition and the preparation method of electric hammer lubricating grease.
Background technology
Electric hammer is the class in electric drill, is mainly used to hole on concrete, floor, brick wall and stone material.Also have multifunctional electric hammer, be adjusted to appropriate location and mix suitable drill bit and can replace common electric drill, electric pick uses.
Electric hammer is made up of electric motor, gear reducer, crank connecting link beater mechanism, rotating drill rod mechanism, overload protection arrangement, power switch and power supply coupling unit part etc.
The rotary motion of electric motor, by gears meshing, is transferred to the rotating drill rod mechanism of eccentric link beater mechanism and straight bevel gear pair, respectively to obtain required ballistic work and torque.
Shock motion by gear driven eccentric rod gear, makes displacer reciprocating in cylinder sleeve by electric motor rotary motion, produces air cushion between displacer and impact piston simultaneously.Impact piston is hammering drilling rod afterbody with displacer synchronous reciprocating, thus makes to build work drilling holes.Due to the formation of air cushion, play again shock absorption during machine stress rebound.
Turn pricker motion by electric motor by gear driven a pair straight bevel gear, cylinder sleeve is rotated together with six square sets through overload protection arrangement, and transmitting torque is to drilling rod.Like this, define with beater mechanism the compound motion impacting and be with and rotate simultaneously.Impact is main, rotates to be auxiliary, hammers not only but also turn, thus makes to build the propelling of work brill, breaks into required circular hole gradually.
Electric hammer mechanical part fault is topmost is exactly do not impact and impact unable, and the main reason of not impacting is exactly that cushion rubber on piston and block stamp is aging, and insufficient lubrication also may impact unable, and these two kinds of fault modes are all closely related with the character of lubricating grease.
The present invention adds from base plinth oil ﹑ multiviscosisty agent ﹑ and adds agent ﹑ grease making process and physical and chemical index etc. and contrast, and the work characteristics in conjunction with electric hammer is that impact load, cylinder spot temperature are high.The present invention can reduce the senile abrasion of air cylinder of electric hammer O-ring seal, improves barrier propterty, can extend the life cycle of electric hammer simultaneously.Special product for equipment characteristic exploitation can improve lubricating efficiency, reduces unnecessary loss.
Summary of the invention
