1 : Deep groove ball bearing 

Deep groove ball bearing is one of the most common types of rolling bearing.Basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel ball and a set of cage.

Deep groove ball bearing type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure, open without sealing structure refers to the bearing, seal type deep groove ball into dust seal and oil seal.

2. Flange ball bearing 

Flange bearing main use: Flange bearing from printers, fax machines to monitor, in the household goods used in daily life has a flange bearing products show the space of technology. In the size and accuracy requirement of the standard ABEC - level 1, the production of bearings, can satisfy the general use of products.

The advantages of the flange bearing: Ocean shipping with flange series of products, make the axial positioning easier; No longer need to bearing, become more economical. In order to get the bearing low friction torque, high rigidity, good rotation accuracy, use the small diameter of steel ball. The use of hollow shaft, ensure the lightweight and wiring of the space.

Flange bearing features: In ultra small aperture in the miniature bearing, can be divided into ZZ steel bearing dust cover series, RS rubber bearing sealing ring series, the series of teflon bearing sealing ring, flange series, stainless steel series, ceramic ball series, etc. Miniature ball bearings has extensive USES. Suitable for high speed rotation, low friction torque .

5.Coupling Features:

1. Simple structure, inspection, installation is convenient;
2. Both ends fixed end of hard aluminum alloy, the middle for polyurethane elastomer, compact connection without clearance
3. Oil resistance and electrical insulation;
4. Exactly the same clockwise and anticlockwise rotation characteristics;
5. Can absorb vibration, compensation Angle to the radial, and axial deviation;
6. Hold or stop screw fixed connection, can according to customer demand for machining keyway.Metric or inch size of aperture.

Three kinds of coupling

 6.Pulley:

Synchronous wheel is usually called a pulley.Synchronous wheel drive is from the inside of a surface with the spacing ring belt and have appropriate tooth of pulley, runtime, toothed with pulleys tooth meshing transfer movement and power, it is a combination of merits of a belt drive, chain transmission gear drive the new belt transmission.

Synchronous wheel specifications:
(1) trapezoidal tooth
(2) T synchronous belt wheel
(3) HTD (STD) synchronous belt wheel

Synchronous wheel transmission features:
(1) transmission accurately, non-slip at work, have a constant velocity ratio;
(2) is stable and has a buffer and damping capacity, low noise;
(3) the high transmission efficiency, can reach 0.98, energy-saving effect is obvious;
(4) maintenance convenience, without lubrication, low maintenance cost;
(5) the large range of speed ratio, generally can be up to 10, linear velocity can reach 50 m/s, has great power transmission range, can reach several to several hundred thousand watts;
(6) can be used in long distance transmission center distance can reach more than 10 m.
(7) no pollution, there is no pollution and can work in environment is relatively bad places

8.Heatbed/hotbed and hotend extruder

Connection: 12 v 1 a line, another thread after 2, 3, at the same time.
By this time the amount of two wires resistance value is 1.0 ~ 1.2 Ω, real power is 144 w.

24 v connection: a line 2, another thread after 3 (1 dangling don't pick up), two lines of resistance value is 4.0 Ω, actual power for 24 * 24/4 = 144 w.
The new circuit, whether meet the 12 v or 24 v, the power is stable in 144 w.
Tested, 144 w can make hot bed temperature of 130 °, and fully meet user requirements.

Features:
1, 12 v power supply 24 are compatible.
2, double panel, the other side without wiring, uniform heating, printing effect smooth.
Regardless of is negative 3, wiring, wiring at will.

Test report:
Pick up the 12 v
Current is 9.8 A, as the temperature increases, the current dropped to 8.8 A (as the temperature rises, the little knowledge of the physics: resistance)
After 24 v
The theory of maximum current is less than 5A

9.Sleeve bushing/spacer

  Copper sleeve Is on the high strength of brass substrate, enchase a high-performance solid lubrication graphite or MoS2 solid lubricant products. It broke through the general bearing on the limitations of the oil film lubrication. In use process, through the friction heat make solid lubricant and shaft friction, the excellent conditions of forming, powder and oil lubrication, both to protect shaft wear and tear, and the solid lubrication characteristics of eternity. It is twice as tall as general copper sleeve, wear-resisting performance is twice as high.
