A planetary rolling bearing. A bearing main body comprises an inner ring, an outer ring, a ball track, main rollers and auxiliary rollers. The inner ring and the outer ring are sleeved together in a way of coincided central axes; the outer side of the inner ring and the inner side of the outer ring form the ball track; rollers in the ball track comprise a main roller group and an auxiliary roller group; the rollers are arranged in a planetary shape, namely axes of every three rollers form an isosceles triangle in the ball track; and each roller body is tangent to another along an axis direction, as well as tangent to the ball track wall. When the bearing works, only rolling friction exists between the main rollers and the auxiliary rollers, and between the main rollers, the auxiliary rollers and the outer ring and the inner ring; and original sliding friction and collision friction between the rollers and a holder do not exist. Compared with the prior art, the invention has beneficial effect that the holder is cancelled to reduce collision friction between the holder and the rollers, effectively reduce high temperature of the bearing and oil loss time, thereby prolonging the service life of the bearing.

The invention is suitable for the technical field of radiators, and provides a radiator protection device, which comprises a first protective cover and a second protective cover which are connected through bolts. First protection structures are arranged at the upper end and the lower end in the first protection cover correspondingly. A second protective structure is arranged on one side of the interior of the first protective cover, and a third protective structure is arranged outside the first protective cover and right faces the water outlet hole; a second protective structure is also arranged in the second protective cover, and a third protective structure is also arranged outside the second protective cover and is opposite to the water inlet hole. Therefore, shaking of a radiator bodycan be effectively buffered, damping is achieved, collision damage to the radiator is avoided, the quality of the radiator is improved, the service life of the radiator is prolonged, and the maintenance cost is reduced.

The invention belongs to the technical field of sensors, specifically a heat-sensitive sensor, comprising a shell with an X-shaped cross section, arc-shaped grooves for fixing cylindrical electric cores are provided on both sides of the shell; a hole is opened in the shell, There is a sensor body in the No. 1 hole, and the end of the sensor body close to the bottom of the No. 1 hole is fixedly connected to the probe through an elastic rod; the No. The hole is in contact with the surface of the battery core; the invention uses the shell with an X-shaped cross-section to effectively isolate and fix the adjacent battery cores while serving as a fixing frame for the sensor, reducing the volume occupied by the special bracket, and at the same time Adjacent batteries are isolated to maintain a good heat dissipation gap, reduce collision friction between adjacent batteries, and further extend the service life of batteries.

The utility model relates to a centrifugal device for sorting round balls, which is used for sorting ceramic balls to obtain round ceramic balls. The connector receptacle may include a tongue. The tongue may be formed using a printed circuit board. The invention includes a sorting disc, a sorting body, a rotating shaft and a power device. The circular opening of the sorting disc is upward, and the bottom surface of the sorting disc is sunken downward to form a hollow separation cavity. The sorting body is installed in the separation cavity. The body is a pyramidal structure, the busbar of the sorting body is a single-leaf hyperbola, the rotating shaft is fixed on the lower bottom of the sorting body, the central axis of the rotating shaft is in line with the central axis of the sorting disc, and the output end of the power device is connected to the rotating shaft , the rotating shaft is connected to the sorting disc through the reduction gear; the application has simple structure and good sorting effect.

The invention discloses a high-efficiency refining processing method for Mount Huangshan Mee tea. The high-efficiency refining processing method for the Mount Huangshan Mee tea adopts a three-dimensional semi-automatic processing system which is mainly based on mechanical coupling and artificially supplemented. The three-dimensional semi-automatic processing system comprises a first plane-surface round sifter for carrying out first round sieving on primary tea; and the three-dimensional semi-automatic processing system further comprises an upper-stage tea production line, a mid-stage tea production line and a lower-stage tea production line which are relatively connected to the first plane-surface round sifter. The upper-stage tea production line, the mid-stage tea production line and the lower-stage tea production line are integrated in one processing system according to characteristics of the primary tea of different specifications in the high-efficiency refining processing method for the Mount Huangshan Mee tea. The tea on the sifter is heated so as to carry out second drying, and then, winnowed by shaking the sifter; split-rolling and further sifter-shaking are carried out on the head No. 4 only; sifter-shaking, stalk-picking and winnowing are performed on the sieved tea so as to screen fixed blanks; and heating, second drying and grading are carried out on the fixed blanks. The high-efficiency refining processing method for the Mount Huangshan Mee tea has the advantages of high production efficiency, low broken tea rate, rational arrangement and small floor area. Productive practices have proven that daily output of the Mount Huangshan Mee tea by adopting the system can be up to 10000 kilograms, so that the production efficiency is greatly improved.

The invention discloses a fixed connection structure of a car navigation host and a control panel. The fixed connection structure comprises a control panel; a jack is formed in the control panel for installation of a socket; the socket is inlaid in the jack; and limiting blocks are arranged at the two sides of the jack and are in contact with the sides of the socket, thereby preventing plugging ofthe socket from the jack. With the flexible and detachable limiting blocks, the socket is limited, so that the service life of the socket is prolonged.
