Ngwakọta hydraulic - eriri ọkọlọtọ abụọ

I. Nhazi nke eri

A na-ekewa 1 eri n'ụdị abụọ nke eriri ime na eriri nke mpụga;

2. Dị ka eze nwere ike kewaa n'ime :1) eri triangle 2) eri trapezoidal 3) eri akụkụ anọ 4) serrated thread;

3. Otu eriri na otutu eri dika ọnụọgụ nke eriri;

4. E nwere ụdị abụọ nke ekpe ịghasa eri na nri ịghasa eri dị ka ntụziaka nke ịghasa ntinye. Ejighị eri nke skru nke aka nri akara, a na-agbakwunye LH maka eriri ịghasa aka ekpe, dị ka M24×1.5LH;

5. Dị ka ojiji dị iche iche si dị, a na-ekewa ya na: metric common thread, threaded sealed pipe thread, non-threaded sealed tube thread, 60° taper pipe thread, metric taper thread, etc.

Metric nkịtị eri

1. Metric nkịtị eri na-anọchi anya isi obodo M, eze profaịlụ Angle 2α = 60 ° (α na-anọchi anya eze profaịlụ ọkara Angle);

2. Enwere ike kewaa eri nkịtị metric ka ọ bụrụ eri nkịtị na eri nkịtị dị mma dịka pitch;

2.1. A naghị egosikarị pitch n'akara nke eri siri ike. Dịka ọmụmaatụ, M20 na-egosi eri siri ike. Akara eriri dị mma ga-egosi ọkwa ọkwa, dị ka M30×1.5 maka eri ọma, ebe pitch bụ 1.5.

2.2. A na-eji eriri a na-ahụkarị maka ijikọ na ijikọ n'etiti akụkụ igwe. Njikọ eriri a na-ejikarị na-eji eri siri ike, na ezigbo eri nwere ike dị ntakịrị elu yana ịrụ ọrụ mkpọchi onwe ka mma karịa eri siri ike nwere otu dayameta aha aha.

3. Mark of metric common thread: M20-6H, M20×1.5LH-6G-40, ebe M na-anọchi anya metric nkịtị eri, 20 na-anọchi anya nominal dayameta nke eri 20mm, 1.5 na-anọchi anya pitch, LH na-anọchi anya ekpe adiana, 6H na 6G na-anọchi anya ịghasa. akara nkenke, yana koodu nkenke nkenke nke ukwu na-anọchi anya eri dị n'ime. Koodu akara nkenke obere obere na-anọchi anya eri dị n'èzí, 40 na-anọchi anya ogologo screwing;

3.1. Ngwunye nke eri na-adịghị ahụkebe na sistemu metric bụ nke a (dayameta nke oghere eriri ala: carbon steelφ = dayameta ọnụ -p; Cast ironφ = dayameta ọnụ -1.05-1.1p; Dayameta nke nhazi eriri mpụga anya rodφ= ọnụ ala dayameta -0.13p ): 

Tebụl 1 Dayameta/pitch nke eri na-enweghị isi na sistemu metric

Dayameta aha aha Pitch P nkedo ígwè ala oghere Carbon steel oghere oghere mpụga eriri carbon nchara oghere oghere mpụ
