  High Durability Two batteries power tools drill Principle: The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and work operation, and the operating device is driven by the transmission mechanism to drive the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. Application: 1. Construction and Industry It is widely used in the reinforcement of building beams, slabs, columns, walls, etc., decoration, wall installation, brackets, railings, billboards, air conditioner outdoor units, guide rails, satellite receiver elevators, steel structure workshops, etc. 2. Medical applications (1) Dental: At the beginning of the 20th century, a wall-mounted three-bend dental drill appeared, with a speed of 4000 r/min, and some even reached 10,000 r/min. The rope wheel-driven three-bend dental drill that we are still widely used is its derivative. thing. (2) Otology: Julius Lempert, the father of modern otology, pioneered the use of electric drills for ear surgery in New York in 1938 to treat chronic ear diseases and reduce the incidence of facial nerve damage. But the electric drills of the time were difficult to control and were very noisy. Modern electric and air drills greatly increase the rotational speed and enhance the cutting capacity. The use of fast cutting drills, diamond drills and irrigation-suction systems enables otologists to quickly complete accurate surgical dissections and greatly reduce operating time. 3. Marine flexible rod drill The utility model relates to a new type of marine drilling equipment, which is mainly used for coring and sampling of the bottom layer of the seabed, and exploration of marine geology and minerals. First, it was successfully developed by the F

• High quality 23122 spherical roller bearing

  2022 / 08 / 18

  A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment.Typically these bearings support a rotating shaft in the [bore] of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply,Spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape,But have a profile that makes them appear like cylinders that have been slightly over-inflated. Spherical roller bearing used in countless industrial applications, where there are heavy loads, moderate speedsand possibly misalignment.
