1. the settlement of micro bearing temperature
(1) method of filling grease
(2) oil Cup
(3) pressure grease method
(4) method of centralized grease 2. micro bearing heating considerations
We often choose micro bearing there will always be a number of questions, and will think is a mess, now small in here for everyone to choose micro bearing some of the elements are summarized, for your reference.
According to the headset or loose beads (rotational structure) in the head tube of the frame parts for: built-in headset, an external headset, semi built-in headset.
Most dead flies are 34mm external headset. Headset parts: upper cover, Sun flowers, Bowl cover, front fork clamp, Palin, upper bowl, Bowl, under Palin, the end of block.
1. performance requirements for bearing parts:
(1) high hardened and hardenability to ensure evenly on the surface, high hardness, thus ensuring its wear resistance;
(2) high fatigue strength and compressive strength in order to ensure a long service life;
2. the heat treatment process of thin-walled bearing:
(1) the main cause of heat treatment deformation
(2) the heat treatment process
Castor is a generic term, including activities and fixed casters casters. Activity is what we call universal wheel casters, its structure allows for 360 degree rotation fixed casters also known as directional casters, it has no rotating structure, can't move. Usually two castors in General is with the use of, such as the structure of the cart is in front of two directional wheels, near the drive is two Hooke′s joints of the arm in the back round.
At the time of choosing the right wheel bearing many factors have to be considered, such as quantity, using the State of the ground, special environment, rotational flexibility, temperature limit this is a factor we have to consider.
1. the number of
2. using the site
3. special circumstances
4. turn the flexibility 5. temperature limits
Castor's origins date back casters of the history is a very difficult thing, in after people invent the wheel, though, handling and moving objects becomes a lot easier, but the wheels can only be run in a straight line, for handling significant objects to the change of direction is still very difficult, people invent the wheel with steering structure, which is what we call the casters and caster. Castor appeared to people handling moving objects in particular have brought epoch-making revolution, not only makes it easy to carry, you can move in any direction, greatly improving efficiency.
In front tube diameter at through Qian fork of Qian fork straight tube, and Qian fork straight tube its wear out front tube of top Department put reset with its bottom Xia pressure front tube and Qian fork straight tube between of car head Bowl and is located in Qian fork straight tube bottom and front tube bottom between of got off head bowl of handles straight tube, and the front Bowl within has bearing, and front tube relative Yu the front bowl of bearing at set reset axis body, and the reset axis body is through relative Yu the front bowl of bearing end margin and set of oblique to reset margin positioning bearing. Both ends of the front tube diameter relative to reset the axle body with chimeric slots SAG, while shaft is provided with corresponding to the chimeric slots projecting chimeric. Characterized, front of the bowl of the pipe relative to the head bearing set reset shaft, and each shaft is by relative to the front of the bowl of the inclined to reset the margins for the bearing edge to bearing. Through the structure, the stable positioning of the bearing, and the composition and maintenance is very convenient.
